Full textLocated within the spinal cord, the locomotor central pattern generators (CPGs) organize the rhythmical activation of limb muscles according to specific gait pattern requirements. These CPGs are under the control of supraspinal centers that are involved in the motivational aspect of locomotor behavior, and their activity is constantly modulated by sensory inputs to adapt the locomotor activities to environmental changes. The aim of my doctoral work was to further understand the dynamic interactions between (1) the supraspinal centers, (2) the CPGs and (3) the sensory inputs in both healthy and spinalized newborn rats. Using the isolated brainstem / spinal cord preparation as an in vitro experimental model, we first showed that manipulating the periodicity and the relative durations of left and right descending reticulospinal commands at the brainstem level is efficient to set the locomotor speed and sustain directional changes. We next established the interaction between the descending serotonergic pathways and sensory feedback to shape the spinal locomotor outputs during the first postnatal week. Finally, by combining behavioral, neurochemical and electrophysiological techniques, we showed different but complementary effects of monoaminergic neuromodulators (serotonin, dopamine and norepinephrine) in the expression of locomotor behavior after a spinal cord injury. Our work brings additional data to better understand the afferent control of locomotor spinal CPGs in healthy and spinalized newborn rats

Full textIdentification of the cellular mechanisms underlying the generation of the locomotor rhythm is of longstanding interest to physiologists. Hindlimb locomotor movements are generated by lumbar neuronal networks, referred to as central pattern generators (CPG). Although rhythm generation mechanisms within the CNS can vary, the activation of a subthreshold depolarizing conductance is always needed to start the firing of individual neurons. Among various subthreshold membrane conductances, the persistent sodium current (INaP) is involved in rhythmic activity of numerous supraspinal neurons such as those involved in the generation of masticatory and respiratory rhythm. The thesis was aimed at identifying and characterizing INaP in the neonatal rodent locomotor CPG, determining its importance in shaping neuronal firing properties and its role in the operation of the locomotor circuitry. Using electrophysiological studies the thesis has characterized INaP for the first time in the locomotor CPG. This current is essential to the generation of the locomotor rhythm and plays a fundamental role in the emergence of pacemaker activity within the CPG. These pacemaker activities emerge in a physiological context in which fluctuations in the ionic composition of the extracellular environment occur during locomotion. This study provides evidence that INaP generates pacemaker activities in CPG interneurons and new insights into the operation of the locomotor network with a critical implication of INaP in stabilizing the locomotor pattern

Full textOur group investigates the lumbar locomotor network using the isolated neonatal rat spinal cord as a model. When appropriately activated, this preparation expresses fictive locomotion (without movement) recorded from the motor ventral roots. In this work, we have shown (1) the powerfull capabilities of dopamine and its D1 receptor agonist, SKF-81297, to generate and/or modulate fictive locomotion and (2) that neuropeptides, poorly studied in our preparation, are modulators that shape the locomotor pattern. Finally, we have studied the activity-dependant plasticity and metaplasticity of the sensorimotor transmission by analyzing the different effects of serotonine, dopamine and noradrenaline. Our preliminary data indicate that the action of these drugs are different depending on the type of plasticity

Full textMaturation of inhibitory postsynaptic transmission onto motoneurons in the rat occurs during the perinatal period, a time window during which pathways arising from the brainstem reach the lumbar enlargement of the spinal cord. There is a developmental switch in miniature IPSCs (mIPSCs) from predominantly long-duration GABAergic to short-duration glycinergic events. We investigated the effects of a complete neonatal [postnatal day 0 (P0)] spinal cord transection (SCT) on the expression of Glycine and GABAA receptor subunits (GlyR and GABAAR subunits) in lumbar motoneurons. In P7 animals with neonatal SCT (SCT-P7), the GlyR densities were unchanged compared with controls of the same age, while the developmental down regulation of GABAAR was prevented. After spinal cord injury, the disruption of flexion/extension and left-right alternations is largely attributed to a deterioration of the inhibitory circuitry below the lesion, but most of the cellular mechanisms are still unknown. Our aim of this was to measure the alteration of the GABA and glycinergic synaptic transmission on lumbar motoneurons (Mns) after spinal cord transection (SCT) in the adult rat, and evaluate the benefit of manual training and stepping recovery on the inhibitory networks. All in all our results show that, the presynaptic and postsynaptic components of the glycinergic synapses are relatively preserved on lumbar Mns. We developed a manual training procedure, based on daily alternate phases of imposed stepping and free walking in enriched environment. Pharmacological treatment with 5-HT2 receptor agonists allowed a standing recovery and alternate stepping

Full textRegeneration after traumatic spinal cord injury generally fails due to a cascade of cellular and molecular events, including blood-spinal cord barrier breakdown,persistent and uncontrolled inflammation, and glial scarring and cavity formation combined with the presence of axon growth-inhibitory molecules. While efficient therapies are still lacking, recent progress in the design of implantable biomaterials may well open up new possibilites for their development. Chitosan hydrogels (hCh) seem particularly promising as their biological properties can be fine-tuned, notably by their degree of acetylation (DA). In the context of a rat dorsal spinal cord hemisection, I have tested different formulations of fragmented hCh for their ability to integrate into lesioned host tissue without creating additional inflammation, or excessive astrocytic reaction. Thus, I found that implantation of hCh particles of 4% DA allows for tissue reconstruction by attracting different cell types and recreating a functional vasculature. Importantly, it modulates the inflammatory response, favoring polarization of invading macrophages towards the M2 phenotype. In lesioned-implanted animals, the glial scar is less fibrous, astrocyte processes are mainly oriented towards the lesion and accompany a robust regrowth of fibers, whose origin was identified by axon tracing and immunohistochemistry. Many of these fibers are myelinated or ensheathed by Schwann cells, maintained at long term in the implant. Finally, this structural remodeling is associated with significant, long-lasting recovery of locomotor function, as I have shown by open-field and gait analysis

Full textRecent studies have shown the key role of the ventral midline thalamus (Reuniens and Rhomboid nuclei; ReRh) in spatial memory persistence in rats, which requires a hippocampo- prefrontal dialogue for consolidation at the systems-level. As enriched environment (EE) promotes the recovery of declarative-like memories after diencephalic (anterior thalamus) lesion, and enhances neuronal plasticity, we tested its impact on the effects of the ReRh lesion upon the consolidation/retrieval of a remote spatial memory in a Morris water maze (i.e. 25 post-acquisition days). For this purpose, we exposed rats for 40 days to an enriched environment beginning 2 weeks after fiber-sparing excitotoxic thalamic lesions. In addition, the expression of the immediate early gene, c-fos, was mapped by immunohistochemistry as a marker of functional activity in the dorsal hippocampus, the median prefrontal cortex (mPFC), the intralaminar thalamic nuclei and the amygdala. Enriched housing allows the recovery of spatial memory persistence capacities in ReRh rats, with additional beneficial effects on anxiety and habituation to a novel environment. Immunohistochemistry of the Fos protein showed a higher recruitment of the mPFC, concomitant with memory capacities recovery in enriched ReRh rats, while in standard ReRh rats, Fos expression in the mPFC was significantly decreased together with the alteration of memory performance. The lesion-induced amygdala hyperactivity in basal and memory conditions was significantly attenuated in the ReRh enriched group. We suggested that amygdala might be involved in the effect of ReRh lesion on memory persistence, and also in the functional recovery associated with the restoration of the mPFC activity during remote memory retrieval in enriched ReRh rats

Full textAlthough it is well admitted that the glutamatergic neurotransmission plays a pivotal role in the development and expression of behavioral sensitization to amphetamine, the specific role of glutamatergic structures that project to the ventral tegmental and/or the nucleus accumbens is less well studied. We showed that the dorsal hippocampus, the prelimbic part of the prefrontal cortex and the basolateral amygdala play a critical role in both acute (development of sensitization) and chronic (expression of sensitization) locomotor responses induced by amphetamine, suggesting that behavioral responses to amphetamine are mediated by circuitry of corticolimbic glutamatergic structures. Next, we investigated the role of glutamatergic NMDA receptors contained in the nucleus accumbens, which is seen as the key structure for the expression of sensitization, in the development of short term sensitization to amphetamine. Interestingly, we showed that, contrasting with the current dichotomous thinking that has attributed specialized functions to the ventral tegmental area and the nucleus accumbens, respectively in the development and the expression of behavioral sensitization, concomitant activation of certain types of NMDA and nicotinic receptors in the nucleus accumbens is also required for the development of short term sensitization. Furthermore, we showed that concomitant activation of these receptors sustained the amphetamine-induced dopamine release in the nucleus accumbens. All these data show that glutamatergic neurotransmission, and glutamatergic structures which project onto mésoaccumbens system, plays a major role in short-term behavioral sensitization to amphetamine

Full textLocomotion, as any other forms of physical activity, mobilizes the autonomic nervous system to match the increasing physiological demand. These autonomic responses mostly rely on the coupling between sympathetic and somatic motor activities. The propriospinal cholinergic system plays an important role in the control of locomotor networks, and several lines of evidences suggest that it may also activate sympathetic preganglionic neurons from the intermediolateral nucleus (IMLs). The aim of my doctoral thesis was to investigate the role of the cholinergic propriospinal system in the coordination between these two systems. Using the in vitro isolated spinal cord from new born rat, we showed that application of acetylcholine synchronized the locomotor and sympathetic networks, via the activation of muscarinic receptors. Indeed, the non-selective agonist oxotremorine induced slow rhythmic activity blocked by M1, M2, M3 and M4 muscarinic receptor antagonists. In addition, oxotremorine revealed endogenous rhythmogenic capabilities of the thoracic segments. This slow oscillatory activity propagated from thoracic ventral roots to lumbar ones, but not the reverse. We observed that thoracic MNs were rhythmically activated during both locomotorlike activity and oxotremorine-induced rhythm. In contrast, IMLs were rhythmically activated solely in the presence of oxotremorine. This study provides new light on the origin of the coupling between the somatic and the sympathetic systems. We propose that synchronizing mechanisms are achieved in part by an intraspinal network which may be activated under the control of the cholinergic propriospinal system

Full textLocomotion involves complex synergistic postural regulation requiring the integrated functioning of all the body musculature, including hind- and forelimb, trunk and neck muscles. Dynamic equilibrium during forward locomotion is preserved by internal process of coordination between neuronal that drive rhythmic contraction of this muscles. Although numerous studies have focused on understanding how the CNS controls hindlimb movements, very few studies has been devotes to understanding the functioning of neural networks that activate trunk muscles in coordination with limb movements. To answer approach these question three main approaches have been used. (1) a kinematic approach allowing to visualize from birth to weaning day, the rat movements in a 3-D environment ; (2) an electrophysiological approach on an in vitro isolated spinal cord preparation based on spinal neuronal networks responsible for motor activity in the newborn rat ; (3) an electromyographic approach to determine the pattern of activity of axial movements in human. Our results show that there is a rhythmic sequential change in trunk curvature during the step cycle. In rats, development modifies the amplitude an velocity of the motor output. The trunk bending could be related to the sequential propagation of the motor wave along the spinal cord. Our data suggest that the networks responsible for metachronal propagation of motor patterns during locomotion may correspond to those observed in vertebrates or lower vertebrates, and thus are highly conserved

Rat ultrasonic vocalizations of fundamental frequency in the 30-90khz range known as '50 khz' usvs, are related to appetitive contexts such as social interactions, reward and mating. However, how these vocalizations contribute to rat social behaviour is not completely understood. Previous data from our lab shows that these usvs are tightly synchronized with the locomotion of the emitting rat, thus raising the possibility that vocalizations could help rats track each other in the dark. We here tested this hypothesis by assessing how devocalizing one or both rats in a male-female pair affected their spatial interactions during mating behavior. Metrics of spatial correlation, such as average distance between the two animals and number and duration of chases were analyzed for each record. Preliminary results suggest that, although devocalization does not influence success of mating, it may specifically interfere with fast spatial interactions.

Resumo: A locomoção representa um comportamento extremamente importante e primordial para a vida animal. Diante disso, torna-se notório que o restrito confinamento imposto aos animais de laboratório pode causar negativas implicações fisiológicas, uma vez que diversos comportamentos locomotores naturais são suprimidos. Baseado nessa problemática, desejamos verificar se animais alojados em gaiolas convencionais possuem piores indicadores de desempenho ao exercício, quando comparados a animais expostos a condições aumentadas de espaço físico. Além disso, buscamos analisar se a característica do espaço físico das gaiolas representa um fator mais relevante que a própria aplicação do exercício, haja vista que protocolos de treinamento físico em modelos animais não conseguem promover melhoras expressivas da capacidade aeróbia ao longo da idade. Em outra temática, a locomoção também se apresenta intimamente relacionada a aspectos genéticos, uma vez que marcantes diferenças individuais são distinguidas quando rodas de atividades são disponibilizadas para animais de laboratório. Entendendo que o aspecto genético é de suma importância nesse contexto, nós supomos que animais mais ativos na gaiola, exibiriam maiores vantagens metabólicas e genéticas para a prática de exercício quando comparados a animais mais inativos. Diante disso, buscamos explorar se as atividades espontâneas e voluntárias dos animais já refletem propensões para melhores desempenhos físicos. Embora pareçam similares, tais atividades são consideradas distintas pela literatura, e carecem de serem relacionadas com a capacidade aeróbia, e com respostas moleculares envolvidas com a performance. Tendo em vista todos os temas abordados, o objetivo geral do presente projeto baseia-se em verificar a influência do espaço físico da gaiola, bem como sua interação com as duas principais intervenções experimentais científicas (treinamento físico ou livre acesso à roda de atividade) sobre respostas fisiológicas e moleculares relacionadas com o metabolismo aeróbio e anaeróbio, composição corporal e estresse em ratos ao longo da idade (60, 90 e 150 dias). Além disso, verificar as relações entre a atividade espontânea e voluntária com parâmetros fisiológicos envolvidos com a performance no exercício
Abstract: Locomotion is extremely important and essential for animal life behavior. Thus, it becomes clear that the restricted confinement and therefore the suppression of many locomotors behaviors imposed to laboratory animals can cause negative physiological implications. Based on these problems, we verified if animals housed in conventional cages have worse exercise performance indicators when compared to animals exposed in increased housing space. Furthermore, we analyzed if the physical space of the cages is a more important factor than implementation of the exercise, given that physical training protocols in animal models fail to promote improvements in aerobic capacity over the age. On another topic, locomotion is closely related to genetic factors. We assumed that animals more active in the cage, exhibit higher metabolic and genetic advantages for the practice of exercise when compared to inactive animals. Therefore, we investigated whether the spontaneous and voluntary activities of animals already reflect propensities for better physical performance. Although they look similar, these activities are considered distinct in the literature. There is scarce information about the relationship of such with aerobic capacity and molecular responses involved with the performance. The overall goal of this project is based on checking the influence of the housing space of the cage as well as its interaction with the two main scientific experimental interventions (physical training or free access to activity wheel) on physiological and molecular responses related aerobic and anaerobic metabolism, body composition and stress in rats along age. In addition, to check the relationship between spontaneous and voluntary activity with physiological parameters involved with the exercise performance
