Abstract: The study aimed to determine age related changes in the brain of healthy domesticcats by MRI. The hypotheses of this study are that cats show dilatation of cerebralventricular system, brain atrophy and focal changes in the intensity of the brain signal asadvancing age. Multiplanar images on T1-weighted, T2-weighted, FLAIR, GRE T2 andpost-contrast T1-weighted sequences were obtained from 12 adult (1-6 years), 11 mature(7-11 years) and 10 geriatric cats (12 years or more) in an low-field MRI equipment. Theheight and the percentage of the right lateral ventricle volume in relation to theintracranial volume, as well as the width and the percentage of the third ventricle volumein relation to the intracranial volume, were significantly higher in geriatric compared tothe adult animals. The geriatric cats also demonstrated thickness of the interthalamicadhesion and percentage of cerebral parenchymal volume in relation to intracranialvolume significantly lower than those found in the adult group. The results of this studyconfirm the hypotheses related to ventricular dilatation, specifically of the right lateralventricle and third ventricle, and cerebral atrophy, as well as the interthalamic adhesion,with increasing age in cats. However, the results have not ratified the hypothesis relatedto the cerebellar atrophy and focal changes in the intensity of the brain signal in cats asadvancing age.

Individuals with autism present with a constellation of social, behavioral, and cognitive symptoms. A striking characteristic is the contrast between their language and visual processing abilities. The work in this thesis combines behavioral, functional MRI, and diffusion tensor imaging methods to examine the neurobiological basis of the discrepancy between linguistic and visuospatial skills in autistic cognition. A pictorial reasoning task, designed to manipulate the degree to which language vs. visuospatial abilities may be differentially engaged in solving picture puzzles, was administered under three conditions: visuospatial, semantic and a hybrid visuospatial-cum-semantic condition. Whereas participants with Asperger's syndrome and typically developing controls (CTRL) were found to exhibit similar performance profiles, high-functioning individuals with autism (HFA) differed from these two groups: they were least efficient on the semantic condition and appeared to benefit from and favor the use of visuospatial mediation in problem solving. Results from functional MRI revealed a pattern of decreased activation in fronto-temporal language areas, and an increased reliance on posterior brain regions in the parietal and ventral temporal lobes in HFA, supporting the earlier behavioral findings. Specifically, the inferior frontal gyrus appeared to play an important role in verbal mediation and semantic integration in CTRL, whereas HFA relied more extensively on inferior and ventral regions of the temporal lobe, in keeping with a cognitive preference for visual strategies.
(cont.) An examination of white matter integrity yielded a similar finding in the relationship between structural neuroanatomy and cognitive profile, such that connectivity patterns were related to the semantic mediation difficulties and visual processing preference in the HFA group: tracts relevant for semantic processing in CTRL were disrupted in HFA along the superior longitudinal fasciculus and in the frontal lobe, whereas parietal and inferior temporal white matter supporting visuospatial processing were intact in HFA The results suggest that performance in high functioning autism may be related to deficits in frontal cortex connectivity, in favor of visualization strategies in higher-level cognition. The findings appear to support the use of visuospatial vs. linguistic tasks to differentiate between potential subtypes on the autism spectrum.

Pełny tekst źródłaLittle is known about the role that tachykinins, such as substance P and its receptor, the neurokinin-1 receptor, play in the generation of sympathetic nerve activity and the integration within the ventrolateral medulla (VLM) of many vital autonomic reflexes such as the baroreflex, chemoreflex, somato-sympathetic reflex, and the regulation of cerebral blood flow. The studies described in this thesis investigate these autonomic functions and the role of tachykinins through physiological (response to hypercapnoea, chapter 3), anatomical (neurokinin-1 receptor immunohistochemistry, chapter 4) and microinjection (neurokinin-1 receptor activation and blockade, chapters 5 and 6) experiments. In the first series of experiments (chapter 3) the effects of chemoreceptor activation with hyperoxic hypercapnoea (5%, 10% or 15% CO2 in O2) on splanchnic sympathetic nerve activity and sympathetic reflexes such as the baroreflex and somato-sympathetic reflex were examined in anaesthetized rats. Hypercapnoea resulted in sympatho-excitation in all groups and a small increase in arterial blood pressure in the 10 % CO2 group. Phrenic nerve amplitude and phrenic frequency were also increased, with the frequency adapting back to baseline during the CO2 exposure. Hypercapnoea selectively attenuated (5% CO2) or abolished (10% and 15% CO2) the somato-sympathetic reflex while leaving the baroreflex unaffected. This selective inhibition of the somato-sympathetic reflex while leaving the baroreflex unaffected was also seen following neurokinin-1 receptor activation in the rostral ventrolateral medulla (RVLM) (see below). Microinjection of substance P analogues into the RVLM results in a pressor response, however the anatomical basis for this response is unknown. In the second series of experiments (chapter 4), the distribution of the neurokinin-1 receptor in the RVLM was investigated in relation to catecholaminergic (putative sympatho-excitatory “C1”) and bulbospinal neurons. The neurokinin-1 receptor was demonstrated on a small percentage (5.3%) of C1 neurons, and a small percentage (4.7%) of RVLM C1 neurons also receive close appositions from neurokinin-1 receptor immunoreactive terminals. This provides a mechanism for the pressor response seen with RVLM microinjection of substance P analogues. Neurokinin-1 receptor immunoreactivity was also seen a region overlapping the preBötzinger complex (the putative respiratory rhythm generation region), however at this level a large percentage of these neurons are bulbospinal, contradicting previous work suggesting that the neurokinin-1 receptor is an exclusive anatomical marker for the propriobulbar rhythm generating neurons of the preBötzinger complex. The third series of experiments (chapter 5) investigated the effects of neurokinin-1 receptor activation and blockade in the RVLM on splanchnic sympathetic nerve activity, arterial blood pressure, and autonomic reflexes such as the baroreflex, somato-sympathetic reflex, and sympathetic chemoreflex. Activation of RVLM neurokinin-1 receptors resulted in sympatho-excitation, a pressor response, and abolition of phrenic nerve activity, all of which were blocked by RVLM pre-treatment with a neurokinin-1 receptor antagonist. As seen with hypercapnoea, RVLM neurokinin-1 receptor activation significantly attenuated the somato-sympathetic reflex but did not affect the sympathetic baroreflex. Further, blockade of RVLM neurokinin-1 receptors significantly attenuated the sympathetic chemoreflex, suggesting a role for RVLM substance P release in this pathway. The fourth series of experiments (chapter 6) investigated the role of neurokinin-1 receptors in the RVLM, caudal ventrolateral medulla (CVLM), and nucleus tractus solitarius (NTS) on regional cerebral blood flow (rCBF) and tail blood flow (TBF). Activation of RVLM neurokinin-1 receptors increased rCBF associated with a decrease in cerebral vascular resistance (CVR). Activation of CVLM neurokinin-1 receptors decreased rCBF, however no change in CVR was seen. In the NTS, activation of neurokinin-1 receptors resulted in a biphasic response in both arterial blood pressure and rCBF, but no significant change in CVR. These findings suggest that in the RVLM substance P and the neurokinin-1 receptor play a role in the regulation of cerebral blood flow, and that changes in rCBF evoked in the CVLM and NTS are most likely secondary to changes in arterial blood pressure. Substance P and neurokinin-1 receptors in the RVLM, CVLM and NTS do not appear to play a role in the brainstem regulation of tail blood flow. In the final chapter (chapter 7), a model is proposed for the role of tachykinins in the brainstem integration of the sympathetic baroreflex, sympathetic chemoreflex, cerebral vascular tone, and the sympatho-excitation seen following hypercapnoea. A further model for the somato-sympathetic reflex is proposed, providing a mechanism for the selective inhibition of this reflex seen with hypercapnoea (chapter 3) and RVLM neurokinin-1 receptor activation (chapter 5). In summary, the ventral medulla is essential for the generation of basal sympathetic tone and the integration of many vital autonomic reflexes such as the baroreflex, chemoreflex, somato-sympathetic reflex, and the regulation of cerebral blood flow. The tachykinin substance P, and its receptor, the neurokinin-1 receptor, have a role to play in many of these vital autonomic functions. This role is predominantly neuromodulatory.

Pełny tekst źródłaThe wide diversity of eye designs present in arthropods makes them a unique group for studying the diversity and evolution of the visual system. However, most of our knowledge on the development and the neural architecture of the visual system comes from few model organisms. My project aims to contribute to the study of the diversity and evolution of the arthropod visual system by studying the eye of the crustacean Parhyale hawaiensis; focusing on its development, neuroarchitecture and function. In particular, my work aims to characterize the structure of the visual system, to map the connections between photoreceptors (PR) and optic lobe (OL) and to understand the functional adaptations of the eye, in relation to the eyes of other arthropods.A description of the basic anatomy of the visual system was performed by means of electron microscopy, immunostainings and by generating transgenic reporter lines. I found that Parhyale has an apposition-type compound eye with 8 (in hatchlings) to 50 (in adults) ommatidia, each one formed by 5 PR cells (R1-R5).Two opsins were found in Parhyale, named Ph-Opsin1 and Ph-Opsin2, which are exclusively expressed in the retina. Using the genome sequence as a guide, I cloned upstream regulatory sequences from each opsin genes and generated transgenic reporters that recapitulate the expression patterns of Ph-Opsin1 and Ph-Opsin2. These reporters revealed that R1-R4 express Ph-Opsin1 while R5 expresses Ph-Opsin2.Immunostainings and live imaging of the two transgenic lines showed that PR cells send long projections from the retina to the OL, via an optic nerve. Three optic neuropils were identified: lamina, medulla and a deeper neuropil, possibly the lobula or lobula plate. Following the axonal projections of the PR into the brain, revealed that all PR project to the lamina. This differs from what has been shown in dipterans and crustaceans, where at least one PR per ommatidium projects to the medulla. Electron microscopy showed that the rhabdomeres of two pairs of PR, R1+R3 and R2+R4, are orthogonally aligned to each other in each ommatidium, and that the rhabdom does not rotate. These features render the PR intrinsically sensitive to specific directions of light polarisation. Therefore, I tried to understand whether and how Parhyale respond to polarised light. I developed two experimental setups to address whether Parhyale shows behavioural responses triggered by light polarisation. The data I have collected suggest that Parhyale are phototactic to dim white light but show no response to polarised light in these specific experimental assays. Potential problems with these behavioural assays are discussed.Finally I show that the eye of Parhyale quickly adapts to different conditions of light intensity. This is achieved by movement of the shielding pigment granules, located inside the PR cells and by morphological changes of the PR basal membrane.This project is pioneering the study of the visual system in Parhyale. It is the first time that genetic tools have been introduced to study the crustacean visual system. It establishes Parhyale as a powerful experimental system for in vivo studies of compound eye development and axonal targeting, a field currently dominated by studies in a single species of fruitfly

Pełny tekst źródłaThe objective of this study is to describe the anatomical organization of the pineal gland of the Cebus apella monkey, analyzing its macrocospic and microscopical aspects, seen under the optics of the light microscopy, electronic microscopy of transmission and microanalysis by emission of X-Ray. In the development of this study 12 units of Cebus apella monkey, supplied by IBAMA ? MG, were used. For the macrocospic analysis we used 12 animals, which had been used for topography and related to pineal body related studies. From this group, seven specimens were used on the light microscopy, one specimen on electronic microscopy of transmission and one specimen on electronic microscopy of scanning. All the specimens were prepared according to histological techniques of routine. The pineal gland of the Cebus apella monkey presented itself as a small organ of variable forms and lengths, measuring 2,5mm to 4,0mm in length and 2,0mm to 3,5mm in width. It is caudally located to the esplenium of the calosus body, in relation to the pineal recess, being classified as subcalosus and type A according to Vollrath (1981). It is externally covered by a conjunctive tissue capsule, rich in collagen fibers, derived from the piamater. In the glandular parenchyma three types of cells are verified: pinealocytes, cells of the glia and mast cells. According to the morphologic characteristics of the cores, we identify pinealocytes of type I and pinealocytes of type II. Corpora arenaceae round and in morula shape are seen in the glandular parenchyma in which the microanalysis by emission of X-Ray showed two main components: the phosphorus and the aluminum

Pełny tekst źródłaThe knowledge of many aspects of Neuroanatomy of non-human primates - which is currently poor due to the lack of studies on the subject - is very important not only for the intrinsic significance of the knowledge itself but also because it contributes for a better understanding of the evolution of the group, which represents a relevant factor for its preservation and protection. The objective of this study is to perform morphological researches on the hypophysis of the Cebus apella monkey in order to understand this structure better and to provide basis for wider comparative analyses. Eleven animals were used on this study. Seven of them were properties of the research collection of the Federal University of Uberlândia and the other four were donated by the IBAMA-MG. The preparation of the anatomical parts was carefully done through dissection of the specimens, whose encephalus were removed from their skulls preserving all their structures. The hypophysis, after having their macroscopy registered, were submitted to histological methods of routine for observation in light microscopy and electronic microscopy of transmission. We could conclude from the obtained results that the hypophysis, on this particular animal, is a intracranial gland lodged in the sela turcica fixed to the base of the brain by the infundibulum which is very short. It has in dens shape and it presents itself as a single mass, because, macroscopically, it is only possible the identification of a discrete division in an anterior lobe and another posterior one besides the infundibulum. The histological analyses show this gland divided in three lobes: anterior (adenohypophysis), intermediary and posterior (neurohypophysis). Through the electronic microscopy of transmission it was possible to identify and classify four cellular types related to the adenohypophysis: types I, II, III and IV. The aspect of the cores of these cells, frequently showing deep invaginations of their membranes, confers to hypophysis of the Cebus apella monkey, peculiar characteristics, which instigates us to carry on performing new studies on the subject

Pełny tekst źródłaThe investigation into the relationship between neural plasticity in the rat forebrain associated with opiate-induced behaviours yielded two major results. The major finding of the functional neuroanatomy of acute morphine dependence was that doses of naloxone that induced hyperalgesia following a brief exposure to morphine, in previously drug-naïve rats, caused a specific induction of the inducible transcription factor (itf) proteins c-Fos and zif268 in the extended amygdala. Moreover, doses of naloxone that caused a simple reversal in morphine analgesia failed to induce itf proteins in these same brain regions. This increase in itf proteins was specific to regions of the extended amygdala that receive and process nociceptive information relayed via the spino-parabrachio-amygdaloid pathway and was not observed in other regions that are involved in supraspinal pain modulation such as the rostral ventromedial medulla and the periaqueductal gray. We also found that acute morphine increased c-Fos protein in the basolateral amygdala and the major output nucleus of the central amygdala the medial subdivision. Acute morphine also up-regulated c-Fos protein in striatal, midbrain, and hypothalamic nuclei. A unique finding of the current study was that prolonged exposure to morphine was required to induce c-Fos in these brain regions, as the subsequent administration of naloxone 30-minutes after morphine either reversed or blocked this induction. These results indicate the potential role of the amygdala in analgesia following systemic morphine and in pain facilitation during acute morphine abstinence. Investigation into the neurons and circuitry that undergo long-term neuroplasticity in response to repeated morphine exposure revealed that network-level changes in the distribution of Fos protein in the nucleus accumbens and striatum predicted both tolerance to catalepsy and psychomotor sensitisation. Drug-naïve rats became profoundly cataleptic following morphine, an effect that rats with a drug-history became tolerant. Rats with a history of morphine exposure showed an increase in stereotyped behaviours compared to drug-naïve rats. The major finding of this study was that a shift in the induction of c-Fos protein from a matrix predominance in drug-naïve rats toward a patch predominance in drug-sensitised rats in the accumbens core predicted both tolerance to catalepsy and sensitisation of oral stereotyped behaviours. Acute injection of morphine in a drug-naïve rat induced catalepsy and increased the number of c-Fos-positive neurons in matrix striatopallidal projection neurons of the rostral accumbens core. An increase in activity of striatopallidal projection neurons, which give rise to the indirect pathway, could potentially increase inhibitory drive to the pedunculopontine nucleus (PPN). The PPN, long known as a site of termination for basal ganglia output, is thought to direct the outflow of incentive-motivational and sensorimotor information from the nucleus accumbens to pons, medullary, and spinal cord nuclei translating the incentive impact of the stimuli into appropriate motor, autonomic and emotive responses (Winn et al., 1997). Inhibition of this nucleus would cause the animal to be unable to initiate a movement and in effect lock up, which is precisely what cataleptic postures look like. In contrast c-Fos-positive neurons were decreased in the rostral matrix and increased in patch striatonigral projection neurons along the rostro-caudal extent of the accumbens core when morphine was administered to drug-sensitised rats. Striatonigral neurons located in the patch give rise to the direct pathway innervating the dopaminergic neurons in both substantia pars compacta and the dopamine rich islands in the substantia nigra pars reticulata (Berendse et al., 1992; Gerfen, 1992; Furuta et al., 2002). Activity of this pathway is thought to be involved in the initiation of movement (Gerfen, 1992; Gerfen and Wilson, 1996), however, when this pathway is overstimulated as is the case when morphine is injected in drug-sensitised rats this could potentially cause increased activity of PPN neurons leading to repetitive psychomotor behaviours or stereotypy. This data adds to the growing body of evidence that suggests that long-term neuroadaptations induced by drugs of abuse including morphine that lead to behavioural sensitisation involves the circuitry that includes the nucleus accumbens.

Pełny tekst źródłaComparative Anatomy of mammals has been a relevant theme of researches in the biomedical and biological areas with the objective of looking for more information that can aid for searching on the understanding of the unit-variety complex. Among the simians, Baboon and Rhesus have been particularly focused, although they are not from the New World. The monkey Cebus apella, animal of the forests of the South American continent, being geographically distributed for almost the whole Brazil, presents satisfactory adaptation to the captive life showing a great easiness of reproduction. Thus, we intended to study the monkey Cebus apella, analyzing the origin, the composition and the resulting nerves of its brachial plexus. The immediate objective of this study was to add information to the knowledge of its Anatomy, seeking the supply of subsidies for anatomo-functional interpretations of Cebus apella comparatively to humans and domestic animals. Further, we propose to establish the anatomical pattern of this animal, culminating with the elaboration of an Atlas - text on the Anatomy of the monkey Cebus apella. Twenty adult animals, 10 male and 10 female, belonging to the collection of anatomical pieces of the Anatomy Laboratory of the Federal University of Uberlândia were obtained and prepared through fixation and dissection. The major nerves originating from the brachial plexus were: the suprascapular, the subscapular, the musculo-cutaneous, the radial, the median, the ulnar, the axillary, the thoraco-dorsal, the pectoralis major and the pectoralis minor. In the dissected specimens, the brachial plexus of Cebus apella was constituted by the roots from C5 to T1 (55,00 ± 11,12%), from C5 to T2 (25,00 ± 9,68%), from C4 to T1 (15,00 ± 7,98%) and from C4 to T2 (5,00 ± 4,87%). The ventral plan of the brachial plexus contributed for the formation of the following nerves: the phrenic, the subclavius, the pectoralis major, and the pectoralis minor. The medium plan originated the musculo-cutaneous, the median, the ulnar, and the forearm medial cutaneous nerves, while the dorsal plan originated the suprascapular, the subscapular, the axillary, the radial, thoraco-dorsal and the long thoracic nerves. In addition, the occurrence of pre- and post- fixation of the plexus as well as its cranial and caudal displacement have been discussed. In conclusion, the brachial plexus of Cebus apella constituted by the roots from C5 to T1 is organized in a simpler ventral plan, a medium plan of intermediate complexity and a more complex dorsal plan.

For many years, it was considered a rather uncommon condition, caused by unconscious conflict, and somewhat resistant to treatment. In recent decades, however, it has emerged that OCD is a highly prevalent disorder, mediated by particular neuroanatomical circuits (e.g. striatal pathways) and neurochemical systems (e.g. the serotonin system), and responsive to treatment with serotonin reuptake inhibitors (SRIs) . Nevertheless, many questions remain; about the specificity of neuroanatomical findings to OCD, about the role of the multiple serotonin (5-HT) receptor subtypes (e.g. 5-HT10)' and about the appropriate pharmacotherapy for patients resistent to SRI treatment? In a series of studies, 1) the neuroanatomy of OCD was assessed by means of magnetic resonance imaging and neuropsychological testing, 2) the neurochemistry of OCD was assessed by means of functional brain imaging after administration of a 5-HT10 agonist, and 3) the pharmacotherapy of OCD was explored in a series of treatment-refractory OCD and OCD spectrum disorder patients using SRI augmentation with a dopamine blocker. Although no significant difference was found in the volume of the caudate in women with OCD and controls, there was a significant correlation between caudate volume and neuropsychological dysfunction in patients, consistent with evidence of striatal involvement in OCD. Functional imaging demonstrated behavioural heterogeneity, but brain-behaviour correlations were positive, consistent with preclinical evidence of a role for the 5-HTlD receptor in the mediation of OCD. Finally, preliminary treatment findings with dopamine blocker augmentation of a SRI were promising, consistent with preclinical understandings of the interactions between the dopamine and serotonin systems. Although oeD is a complex disorder, a number of future research avenues hold promise for providing a thorough delineation of its pathogenesis.
AFRIKAANSE OPSOMMING: Obsessief-kompulsiewe steuring (OKS) word gekenmerk deur indringende gedagtes (obsessies) en herhalende gedagtes of gedrag (kompulsies). Vir baie jare is dit beskou as 'n redelik seldsame toestand wat veroorsaak word deur onbewustelike konflik, en wat in 'n mate teen behandeling weerstandig is. Meer onlangs het dit egter na vore getree as 'n toestand wat baie dikwels voorkom, wat deur spesifieke neuroanatomiese siklusse (bv. striatale bane) en neurochemiese sisteme (bv. die serotonien-sisteem) teweeg gebring word, en wat op behandeling met serotonien heropname inhibeerders (SHIs) reageer. Nogtans is daar steeds baie vrae; oor die spesifisiteit van neuroanatomiese bevindinge vir OKS, oor die rol van die veelvuldige serotonien (5-HT) reseptor subtipes (bv. 5- HT1D), en oor die toepaslike farmakoterapie vir pasiënte wat weerstandig is vir SHI behandeling. In' n reeks van navorsingstudies, is 1.) die neuroanatomie van OKS deur middel van magnetiese resonans beelding en neurosielkundige toetse ondersoek, 2. ) die neurochemie van OKS deur middel van funksionele breinbeelding na toediening van 'n 5-HT1D agonis bepaal, en 3.) die farmakoterapie van OKS in 'n reeks van behandelingsweerstandige OKS en OKS-spektrum steuring pasiënte - waar gebruik gemaak is van SHI aanvulling met 'n dopamien-blokker - ondersoek. Alhoewel daar geen beduidende verskil in die volume van die caudata in vroue met OKS en kontroles gevind is nie, was daar 'n beduidende korrelasie tussen die caudata volume en neurosielkundige wanfunksionering in pasiënte, in ooreenstemming met striatale betrokkenheid in OKS. Funksionele beelding het positief, in demonstreer, maar ooreenstemming met brein-gedrag pre-kliniese heterogeneïteit korrelasies was in gedrag bewyse vir 'n rol vir die 5-HT1D reseptor in die bemiddeling van OKS. Ten laaste, voorlopige behandelingsbevindinge oor dopamienblokker aanvulling van 'n SHI is belowend, in ooreenstemming met v

Pełny tekst źródłaDevelopmental dyslexia is a specific disorder of reading acquisition that affects 3 to 7% of school-aged children. It is well established that dyslexia is partly caused by genetic variations whitch cause changes in brain development, whitch then have consequences at the cognitive level. This Ph.D thesis is based on morphometry analysis of three main sulci of the brain in three large databases of brain magnetic resonance images: 102 participants from France, 80 particpants from Poland and 70 participants from Germany, with, in each database, about half of participants were diagnosed with dyslexia and half of normal readers. I have studied the central sulcus, the Sylvian fissure and the superior temporal sulcus thanks to the automatic labelisation and measures tools in the BrainVISA software. I have measured some quantitative properties (surface and depth) as well as some qualitative ones (configuration) of each sulcus. I have shown a triple interaction between group, sex and hemisphere in the mean depth of the central sulcus. This result allows us to think that control and dyslexic participants may be different in terms of depth asymetry in this particular sulcus. Given that sulcation is an early process during brain development et that it seems to be less plastic than other brain measures (like, for example, grey matter volumes), this result may be an early marker of risk factors for dyslexia rather than a consequence of poor reading

Pełny tekst źródłaThe lateral habenula (LHb) inhibits mesencephalic dopamine neurons through a mesopontine GABAergic node, the rostromedial tegmental nucleus (RMTg). Both LHb and RMTg also project to the dorsal raphe nucleus (DR). The organization of LHb and RMTg projections to the DR was investigated using anterograde tracer injections into the LHb or RMTg and confirmed with retrograde tracer injections. To identify the neurochemical phenotype of RMTg-DR projections, we associated in situ hybridization for GAD67 mRNA with immunohistochemical detection of retrograde tracers deposited in the DR. DR target regions of RMTg projections were characterized using double-imunofluorescence techniques for the anterograde tracer deposited into the RMTg and either serotonin or the type 3 vesicular glutamate transporter. We detected a focal direct projection from the medial LHb division to the caudal DR. In contrast the RMTg emits robust GABAergic projections to a central DR subdivision rich in presumptive glutamatergic neurons.

The collared peccary (Pecari tajacu), a small-sized, omnivorous and diurnal animal, lives in groups of up to 20 animals in several areas of Brazil, the Brazilian northeast included. It is easily adapted to captive breeding and stands out in relation to cattle as an alternative protein source for human consumption, in addition to other commercial applications, posing less damage to the environment. Because there is a scarcity of studies addressing this animal, this work aimed to perform craniometry and morphometry of its cranium, as well as to describe the morphology of the encephalon and its arterial vascularization, in ventral view. We used 14 animals that died of natural causes. These had both their carotid arteries cannulated and fixation in 10% formaldehyde was then performed. From that total, ten animals were injected with latex solution, duly stained, in order to make the blood vessels evident. The skin, as well as the musculature, were rebounded. Craniometric measurements were performed. Subsequently, the encephalons were removed from the crania for measurement, dissection and description. Photographs were taken for demonstration of the structures and, after collection, the database was assembled. In the statistical analysis of the metric data, unpaired Student's t-test and Pearson’s correlation study were conducted. Thus, a significant difference was observed between the male and female collared peccaries, with regard to the Total Head Length, as well as to the face length, the cranium width, face width, and right cerebral hemisphere length, always with higher values for males. In females, the left cerebral hemisphere is wider than the right one. There was a positive correlation between the variable total head length and the right cerebral hemisphere width, in both males and females. The brain-to-body weight ratio of the collared peccaries was, on average, 0.42%. This is a gyrencephalic animal with a developed neocortex, although without evidence of sulci and gyri symmetry between the right and left cerebral hemispheres, nor between the different specimens. The arterial vascularization of the base of the encephalon is presented as a closed circuit, which is dependent on the carotid artery of the encephalon, both the antimeres, and the basilar artery, in all the analyzed specimens. The middle cerebral arteries ranged from one to three vessels, originating from the rostral branch of the cerebral carotid artery. The basilar artery results from the confluence of the vertebral arteries of both the antimeres and the ventral spinal artery. This species tends to fit into type II, of De Vriese's classification
O cateto (Pecari tajacu), animal de pequeno porte, onívoro e de hábitos diurnos, vive em grupos de até 20 animais em diversas áreas do Brasil, inclusive no nordeste brasileiro. É de fácil adaptação à criação em cativeiro e se destaca em relação ao gado como fonte alternativa de proteína na alimentação humana, além de outras aplicações comerciais, com menor dano ao meio ambiente, pois necessita de uma menor área para sua criação. Por tratar-se de um animal ainda pouco estudado, este trabalho objetivou realizar a craniometria e a morfometria de seu encéfalo, bem como descrever a morfologia encefálica e sua vascularização arterial, em vista ventral. Foram utilizados 14 animais que vieram a óbito por causas naturais. Estes tiveram ambas suas artérias carótidas canuladas e, em seguida, realizou-se a fixação em formaldeído a 10%. Deste total, dez animais foram injetados com solução de látex, devidamente corado, para evidenciação dos vasos sanguíneos. A pele foi rebatida, bem como a musculatura. Foram realizadas as medidas craniométricas. Posteriormente, os encéfalos foram retirados dos crânios para a sua medição, dissecação e descrição. Fotografias foram realizadas para demonstração das estruturas, bem como, após a coleta, montou-se o banco de dados. Na análise estatística dos dados métricos, foi realizado o Teste t de Student não-pareado e o estudo de correlação de Pearson. Dessa forma, observou-se que existe diferença significativa entre o comprimento total da cabeça dos catetos macho e fêmea, bem como no comprimento da face, largura do crânio, largura da face e comprimento do hemisfério cerebral direito, sempre com maiores valores para o macho. Nas fêmeas, o hemisfério cerebral esquerdo apresenta-se mais largo que o direito. Ficou evidenciada uma correlação positiva entre a variável comprimento total da cabeça e a largura do hemisfério cerebral direito, tanto nos machos como nas fêmeas. A relação peso do encéfalo/peso do corpo dos catetos foi, em média, de 0,42%. É um animal girencéfalo, com neocórtex desenvolvido, embora sem evidência de simetria dos sulcos e giros entre os hemisférios cerebrais direito e esquerdo, ou entre os diferentes espécimes. A vascularização arterial da base do encéfalo apresenta-se na forma de circuito fechado, sendo dependente da artéria carótida do encéfalo, de ambos os antímeros, e da artéria basilar, em todos os espécimes analisados. As artérias cerebrais médias variaram de um a três vasos, tendo origem a partir do ramo rostral da carótida do encéfalo. A artéria basilar resulta da confluência das artérias vertebrais de ambos os antímeros com a artéria espinal ventral. Esta espécie tende a enquadrar-se no tipo II, da classificação de De Vriese

Pełny tekst źródłaWithin the field of brain mapping, we identified the need for a tool which is grounded in the detailed knowledge of individual variability of sulci. In this thesis, we develop a new brain mapping tool called NeuroLang, which utilises the spatial geometry of the brain.We approached this challenge with two perspectives: firstly, we grounded our theory firmly in classical neuroanatomy. Secondly, we designed and implemented methods for sulcus-specific queries in the domain-specific language, NeuroLang. We tested our method on 52 subjects and evaluated the performance of NeuroLang for population and subject-specific representations of neuroanatomy. Then, we present our novel, data-driven hierarchical organisation of sulcal stability.To conclude, we summarise the implication of our method within the current field, as well as our overall contribution to the field of brain mapping

Resumo: O presente estudo teve como objetivos determinar a prevalência de Desordens Crânio Cervicais em voluntários portadores de Desordens Temporomandibulares; correlacionar os sinais e sintomas envolvidos no acometimento das duas patologias, discutindo possíveis associações; avaliar a possibilidade de contribuição para a elaboração de uma base de dados para diagnóstico, mais ampla. Foram selecionados 200 voluntários do serviço de triagem da Faculdade de Odontologia de Piracicaba da Universidade Estadual de Campinas, os quais foram avaliados por meio da ficha clínica elaborada pelo Centro de Estudos e Tratamento das Alterações Funcionais do Sistema Estomatognático (CETASE) para o diagnóstico de DTM. Os voluntários que apresentavam sinais e sintomas positivos para as Desordens Temporomandibulares foram submetidos a um novo exame clínico para avaliação de Desordens Crânio Cervicais. Os resultados obtidos demonstraram uma prevalência de 69% de Desordens Crânio Cervicais em voluntários portadores de Desordens Temporomandibulares. Entre os principais sinais e sintomas correlacionados de DTM e DCC observamos resultados estatisticamente significantes para dor nas articulações temporomandibulares (p=0,0168), dor espontânea para o músculo temporal (p=0,0049) e, dor à palpação para os músculos temporal (p=0,0016), masseter (p=0,0052) e trapézio (p=0121). Os exames físicos realizados para o diagnóstico de DCC foram bastante específicos, de modo a caracterizar corretamente 95,45% da amostra estudada. Como conclusões pudemos demonstrar que houve uma prevalência de 69% entre a ocorrência de Desordem Crânio Cervical em pacientes portadores de Desordem Temporomandibular; os sintomas de Desordem Temporomandibular que apresentaram correlação com a Desordem Crânio Cervical foram: dor nas articulações temporomandibulares, dor nos músculos masseter espontânea e dor à palpação nos músculos temporais, masseteres e trapézio; o gênero feminino apresentou os maiores índices de Desordem Crânio Cervical em pacientes portadores de Desordem Temporomandibular, o mesmo ocorreu para a faixas etária de 41 a 60 anos e; os testes propostos para a avaliação da Desordem Crânio Cervical foram eficientes
Abstract: The aim of the present study was to determine the prevalence of Cranio SpineDisorders in volunteers presenting Temporomandibular Disorders; correlated signs and symptoms involved in the onset of both diseases, discussing possibilities of associations, assess the possibility of contributing to the develop a good database for diagnosis. 200 volunteers were selected from the screening service at the Piracicaba Dental School, University of Campinas, which were evaluated by the anamnesic questionnaire and clinical exams of the Center of Study and Treatment of the Stomatognathic System Disorders (CETASE) for TMD diagnosis. Volunteers who presented positive signs and symptoms for TMD underwent a new clinical examination for the investigation of the presence of CSD. Our results showed a prevalence of 69% of CSD in volunteers with TMD. Among the major signs and symptoms of TMD related to CSD, we observed statistically significant results for temporomandibular joint pain (p = 0.0168), spontaneous pain for the masseter (p = 0.0049) and pain on palpation to the temporal muscles (p = 0.0016), masseter (p = 0.0052) and trapezius (p = 0121). Physical examinations performed for diagnosis of CSDwere very specific in order to characterize correctly 95.45% of the sample. In conclusion we demonstrated that there was a prevalence of 69% between the occurrence of CSD in patients with TMD; the TMD symptoms that correlated with the CSD were pain in the temporomandibular joints, spontaneous pain in the masseter pain and tenderness in the temporalis muscles, masseter and trapezius muscles; the females had the highest rate of CSD in patients with TMD and the same occurred for the patient aged between 51 and 60 years and; the proposed tests for the evaluation CSD were quite effective

Pełny tekst źródłaMaternal aggression is critical to preserve the litters from male intruders, and the pheromonal cues from the males are important to drive such responses. The ventral premamillary nucleus (PMv) is one of the main targets of the medial amygdalar nucleus, and is critically involved in processing pheromonal information. In this regard, in the present study, we investigated whether the PMv would work as a putative interface between the pheromonal processing of the male intruder and the neural sites potentially involved in the expression of maternal aggression. First, we analyzed the pattern of Fos expression in dams expressing aggressive maternal behavior, and found a significant increase in Fos levels in the PMv, as well as, in most of its main targets, such as the posterior amygdalar nucleus, the posterodorsal part of the medial amygdalar nucleus, the tuberal nucleus of the lateral hypothalamic area, and the ventrolateral part of the ventromedial nucleus. Next, we examined how NMDA lesions bilaterally placed in the PMv would interfere in maternal aggression, and found that dams bearing those lesions presented a significant reduction in the expression of aggressive behavior, but showed no alterations on the maternal behavior responses. Moreover, we were able to see that PMv lesions resulted in significant drop in Fos expression in selected PMv targets, namely the tuberal nucleus of the lateral hypothalamic area and the ventrolateral part of the ventromedial nucleus, likely to be critically involved in the expression of the maternal aggression. Overall, the present results support the idea that the PMv is seemingly a key site in the network controlling maternal aggression; on one hand, the nucleus is likely to processes pheromonal cues from the intruder male, and, on the other, it conveys this information to sites critically related to the expression of maternal aggression.

Pełny tekst źródłaINTRODUCTION: the objective of this research was to measure, through endoscopy, the interventricular foramen choroid plexus and the third ventricle floor structures, as well the distance between the communicating posterior arteries and compare these variables. METHODS: an observational, prospective study was conducted in 37 brains of adult human cadavers, of both sexes at the Death Check Unit of the University of São Paulo, in April 2008 by means of the rigid neuroendoscope. The endoscopic images were recorded, corrected for distortion and measured. The macroscopic measure between the communicating posterior arteries was performed after the endoscopic study. RESULTS: The measures of the interventricular foramen choroid plexus, the latero-lateral distance of mammillary bodies, the distance from the infundibular recess to the mammillary bodies, safety triangle in the tuber cinereum were 1.71 mm (±0.77 mm), 2.23 mm (±0.74 mm), 3.22 mm (±0.82 mm), 3.69 mm2 (±2.09 mm2), respectively. The aspect of the third ventricle floor and the internal distance of the mammillary bodies was 84% opaque and 89% absent, respectively. The mean distance between the communicating posterior arteries was 12.5 mm (±2.3 mm). Associations between the translucent floor of the third ventricle with the following variables: latero-lateral distance and internal distance of the mammillary bodies, as well as age were identified. CONCLUSIONS: Up this research, there was no account on the measures of the interventricular foramen choroid plexus and the distance between communicating posterior arteries at the level of the mammillary bodies. The remaining variables were in greater number and in normal brains, as compared with the literature

This study investigated the relationships between lipopolysaccharide (LPS) -induced maternal sickness behavior during pregnancy and offspring development, behavior, neurochemistry, and neuroanatomy. Pregnant Wistar rats received LPS (100 µg / kg, i.p.) at the gestation day 9.5. Dam\'s sickness behavior was analyzed and at birth, the offspring number and weight were taken. The physical and behavioral development, general activity, play behavior, striatal, hypothalamus and frontal cortex monoamine levels, cerebral morphology, adult\'s social interaction, catalepsy and stereotypy were evaluated in male pups. Results showed that in relation to the control groups LPS treated dams presented a decreased open-field behavior, in food intake and weight gain, but no maternal fever was observed. In offspring: 1) the pups number and self-grooming were reduced and no alterations on physical patterns, behavioral development and exploratory activity were found; 2) striatal dopamine and metabolites levels were smaller in these animal, without differences in noradrenaline and serotonin levels and turnover; 3) play behavior and adult\'s social interaction parameters were reduced; no alterations on cerebral morphology, catalepsy and stereotypy were observed. It was suggested that these animals presented emotional and motivational deficits, but no motor alterations.
