Abstract:
Hemispheric differences in the recognition and manipulation of meaning may be based on distinctions in size, composition, or organization of the right and left semantic networks The present study describes these features of pictorially based semantic networks in 3 subjects with complete forebrain commissurotomy Stimuli were presented for prolonged viewing to the left and right visual hemifields For each trial, the subjects chose from a 20-choice array all pictures that were associated with a target, then indicated the member of each pair of chosen associates that was more closely related to the target The hemispheres' networks were found to be of similar size and composition, but were organized differently The right hemisphere more often produced linear rankings of semantic associates to a target than did the left, and rankings by the two hemispheres were not strongly correlated Hemispheric differences in semantic organization mirror differences in perceptual organization, with the right hemisphere specialized for conventional meaning and the left hemisphere specialized for detecting and processing deviations from standard meaning

Abstract:
Background: Investigating various postnatal parameters of cerebral hemispheres is of great practical value.Objective: To study gender differences in hemispheric parameters and interhemispheric interactions in preadolescent children.Materials and methods: The retrospective study assessed archived brain magnetic resonance images of 60 eight-year-old boys and 60 eight-year-old girls. The analyzed parameters were as follows: 1) hemispheric length; 2) hemispheric width; 3) hemispheric height; 4) width-longitudinal index of a hemisphere; 5) altitude-longitudinal index of a hemisphere; 6) length of frontal lobes; 7) length of parietal lobes; 8) length of occipital lobes; 9) length of temporal lobes. Quantitative indicators were assessed for normal distribution using the Kolmogorov–Smirnov test. Source data were accumulated and arranged in Microsoft Excel 2016 spreadsheets. Statistica 10.0 was used for the statistical analysis. The results were considered statistically significant with P < 0.05.Results: The analysis of cephalometric indicators suggests sex-related variation in the cerebral hemispheres. Based on the obtained data we can identify morphometric parameters of interhemispheric variability that may act as one of the morphometric criteria for the brain asymmetry. The study results can be widely used for neuroimaging.Conclusions: We determined cephalometric reference values for various cerebral hemispheres parts in preadolescent children.

Abstract:
The article presents data on the effect of Mexicor in patients who underwent cardioembolic stroke. Thus, Mexicor improves cerebral hemodynamics in Posterior cerebral circulation and causes a reorganization of the structure of brain bioelectrical activity and the type of frequency-amplitude reorganization is determined by the hemispheric localization of the stroke, which may be due to different hemispheres connection with regulating mesencephalic structures and synchronizing diencephalic structures of the brain. In patients with localization of ischemic lesion in the right hemisphere, Mexicor statistically significantly increases the power in the range of α1-, α2-rhythms in the affected and intact hemispheres, which indicates the active influence of the drug on the synchronizing diencephalo-talamic structures of the brain. In patients with localization of ischemic lesion in the left hemisphere, Mexicor predominantly reduces power in the range of slow rhythms and in the range of β2 rhythms in the two hemispheres, which is caused by increased metabolic and functional activity of the mesencephalic stem brain structures. In patients undergoing cardioembolic stroke, Mexicor has a harmonizing effect on the bioelectrical activity of the brain, and improves cerebral hemodynamics, which gives grounds to recommend the use of Mexicor for the rehabilitation of patients who have undergone cardioembolic stroke.

Abstract:
Background: We aimed to identif y any differences in the structural covariance network based on structural volume and those in the functional network based on cerebral blood flow between the ipsilateral and contralateral hemispheres of pain in patients with episodic migraine without aura.Methods: We prospectively enrolled 27 patients with migraine without aura, all of whom had unilateral migraine pain. We defined the ipsilateral hemisphere as the side of migraine pain. We measured structural volumes on three-dimensional T1-weighted images and cerebral blood flow using arterial spin labeling magnetic resonance imaging. We then analyzed the structural covariance network based on structural volume and the functional network based on cerebral blood flow using graph theory. Results: There were no significant differences in structural volume or cerebral blood flow between the ipsilateral and contralateral hemispheres. However, there were significant differences between the hemispheres in the structural covariance network and the functional network. In the structural covariance network, the betweenness centrality of the thalamus was lower in the ipsilateral hemisphere than in the contralateral hemisphere. In the functional network, the betweenness centrality of the anterior cingulate and paracingulate gyrus was lower in the ipsilateral hemisphere than in the contralateral hemisphere, while that of the opercular part of the inferior frontal gyrus was higher in the former hemisphere.Conclusions: The present findings indicate that there are significant differences in the structural covariance network and the functional network between the ipsilateral and contralateral hemispheres of pain in patients with episodic migraine without aura.

Abstract:
200 hemispheres of the brain of people who died from diseases not related to brain pathology were studied. Morphometric method was used and statistical analysis was completed. It was found out that the width of the right and left hemispheres of the brain in both men and women of brachycranial skull type is slightly greater than of mesocranial and dolichocranial ones. Men and women with dolichocranial skull type have the width of the left hemisphere greater than the right one. Men have the width of the left and right hemispheres greater than women. The limits of individual variability of brain hemispheres’ and occipital lobes’ width have been determined taking into account the type of skull and sex. The largest indicators of the cerebral hemispheres’ width are the next: men of the brachycranial skull type have the right hemisphere’s width of the 70.6•10^-3 m, left one of the 71.4•10^3 m width; the women of the brachycranial skull type have the right hemispheres’ width of the 63.4•10^-3 m and the left one of the 63.8•10^3 m, the women of the mesocranial skull type have the left hemisphere’s width of 63.7•10^3 m. The smallest indicators of the cerebral hemispheres’ width are: men of the dolichocranial skull type have the width of the right hemisphere 44•10^3 m, of the left one of the dolichocranial skull type and of the brachycranial skull type have the width 43.8•10^3 m; women of the dolichocranial skull type have the width of the right hemisphere 38.5•10^3 m, left one of 42.5•10^-3. The largest indicators of the occipital lobes’ width are: men of the brachycranial skull type have the width of the right hemisphere 56•10^3 m, men of the mesocranial skull type have the width of the left hemisphere 65•10^3 m; women of the dolichocranial skull type have the right hemispheres’ width 58•10^-3 m, of mesocranial skull type have the left one is of 63•10^-3 m and of dolichocranial it is of 62.5•10^3 m. The smallest indicators of the occipital lobes’ width are: men of the dolichocranial skull type have the width of the right lobe 41•10^3 m, of mesocranial and brachycranial types it is 42•10^3 m, the width of the left lobe in men with dolichocranial skull type of 38•10^3 m; women of the mesocranial skull type have the right lobe’s width of 36•10^3 m, the left one of dolichocranial skull type it is of 34•10^-3 m. Keywords: endbrain, occipital lobe, individual anatomical variability.

Abstract:
Registration of electroencephalogram (EEG) in the right-handed students during an exam revealed weakening of alpha rhythm in all areas of right and left cerebral hemispheres as well as increased beta rhythm in parietal and end-lobes of the right hemisphere. Simultaneously regular delta waves in the frontal leads ofboth hemispheres and theta waves in right frontal, occipitalis and temporal leads were marked. Offset of EEG slow wave activity in the right hemisphere in partial right-handers was marked in more noticeable way than in that of the true right-handers. The obtained data suggest that the distribution of EEG rhythms in condition of mental and emotional stress in right-handers depends on the type and severity of functional hemispheric asymmetry.

Abstract:
One version of an orthodox rationale for psychological studies of functional hemispheric asymmetry is sketched out. This rationale emphasizes the significance of asymmetry for a psychological taxonomy. An alternative rationale is then presented. This is that the arrangement of the hemispheres with their commissures permits mapping between hemispheres. This mapping may underlie human capacities such as abstraction.

Abstract:
Readers construct at least two interrelated representations when they comprehend a text: (a) a propositional representation containing the individual ideas that are derived from each sentence and the relations among them and (b) a discourse model, a representation of the context or situation to which the text refers. We used a paradigm called “item priming in recognition” to examine how these representations are stored in the cerebral hemispheres. In Experiment 1, the priming paradigm was used in combination with a lateralized visual field (VF) procedure. We found evidence that readers' representations were structured according to propositional relations, but only in the left hemisphere. Item recognition was facilitated when a concept was preceded by another concept from the same proposition when targets were presented to the left, but not to the right, hemisphere. We found priming in both hemispheres, however, when targets were context-appropriate senses of ambiguous words or topics of passages. In Experiment 2, we replicated the priming effects in three callosotomy patients. We argue that the distinction between a propositional representation and a discourse model is important with respect to how discourse is represented in the brain. The propositional representation appears to reside in the left hemisphere, whereas aspects of the discourse model appear to be represented in both hemispheres.

Abstract:
The functional asymmetry of the human brain hemispheres (motor, sensory and mental) reflects the difference in the distribution of neuropsychological functions between its right and left hemispheres. Both hemispheres are involved in the implementation of any types of mental activity or regulation of vegetative physiological processes, but each of them provides different aspects of this activity and some processes domination. Persons with left-hemisphere and right-hemisphere thinking differ in the features of perception, analysis, and reproduction of information, which is important in the process of students' educational activities. That is why the aim of this investigation was to conduct a comparative analysis of the types of the brain hemispheres dominance in students of natural and humanities education who study at the biological and philosophical faculties of the Ivan Franko National University of Lviv and proposed methodological approaches for development and activation both (left and right) brain hemispheres. Methods used in the study: determining the coefficient of functional asymmetry of the brain; general scientific (analysis and synthesis), methods of theoretical research (from abstract to concrete). It was shown that most of the student are dominated by the left brain hemisphere but organizing of the educational process needs to use methods of educational activities aimed at the development and activation both (left and right) brain hemispheres.

Abstract:
The cerebral nuclei form the ventral division of the cerebral hemisphere and are thought to play an important role in neural systems controlling somatic movement and motivation. Network analysis was used to define global architectural features of intrinsic cerebral nuclei circuitry in one hemisphere (association connections) and between hemispheres (commissural connections). The analysis was based on more than 4,000 reports of histologically defined axonal connections involving all 45 gray matter regions of the rat cerebral nuclei and revealed the existence of four asymmetrically interconnected modules. The modules form four topographically distinct longitudinal columns that only partly correspond to previous interpretations of cerebral nuclei structure–function organization. The network of connections within and between modules in one hemisphere or the other is quite dense (about 40% of all possible connections), whereas the network of connections between hemispheres is weak and sparse (only about 5% of all possible connections). Particularly highly interconnected regions (rich club and hubs within it) form a topologically continuous band extending through two of the modules. Connection path lengths among numerous pairs of regions, and among some of the network’s modules, are relatively long, thus accounting for low global efficiency in network communication. These results provide a starting point for reexamining the connectional organization of the cerebral hemispheres as a whole (right and left cerebral cortex and cerebral nuclei together) and their relation to the rest of the nervous system.

Abstract:
Three experiments examined how humans make same-different judgments of simultaneously presented letter pairs using the entire English alphabet, in two tasks: a letter category task in which pairs of letters in different letter cases (instances) belonged to the same (e.g., "X x") or different (e.g., "X o") letter category; and a letter instance task in which pairs of letters in the same letter category belonged to the same (e.g., "X X") or different (e.g., "X x") letter instance. Three experiments used these two tasks to present letter pairs in different arrangements: Experiment 1, centrally to both cerebral hemispheres; Experiment 2, laterally to either the left or right cerebral hemisphere; Experiment 3, laterally to either different hemispheres or to the same hemisphere. The roles of nominal identity (letter names), orthographic identity (how letter graphemes correspond to letter phonemes), and abstract visual-form identity (letter categories) were investigated by examination of letter confusability. The results indicate that visual and not nominal identity is used to perform the letter category task. In addition, women (but not men) used orthographic identity to solve the letter category task during some conditions of all three Experiments. A new kind of analysis indicates that, across-sex, letter category predicts 82% of the variance in response latency to same-category judgments, but only 14% of the variance in response latency to same -instance judgments, functionally dissociating form-invariant (category) and form-variant (instance) visual information. Women (but not men) use form-invariant (category) information when making different-instance judgments--even when such information is insufficient for solving that task--and consequently, women's cerebral asymmetries are shifted and their interhemispheric communication of information is selectively impaired (relative to men) when this information conflicts with that necessary to solve the task. Thus, the kind of information, rather than the number of cognitive processes , determines how processing is lateralized and integrated across the cerebral hemispheres in letter matching tasks. Comparisons of presentations to both and single hemispheres indicate that hemispheric dominance is dissociated from hemispheric asymmetry as a function of sex-dependent attentional strategy and informational conflict in interhemispheric interaction.

Abstract:
Recent research into hemispheric differences in sentence comprehension has produced a puzzling disparity between the results from behavioral studies on neurologically normal individuals and studies utilizing other methods such as electrophysiology, neuroimaging and the investigation of neuropsychological patients. The former approach tends to produce results that indicate a restriction of the right hemisphere (RH) to lower-level processing mechanisms that are comparatively less sensitive to context than the left hemisphere (LH), while the combined findings of the latter approaches suggest that not only is the RH capable of processing language at a higher level, it is particularly sensitive to contextual information and, furthermore, this may form part of the special role of the RH in language tasks. Accordingly, the present series of studies employed a normal-behavioral approach to further investigate the underlying processing mechanisms of the RH during sentence comprehension tasks. In each of the four experiments, right-handed adult participants completed a computer-based lexical decision task where reaction time and error rates were recorded. Stimuli were always centrally-presented, followed by a laterally-presented target word or non-word. In the first experiment, the sensitivity of the RH to message-level meaning was investigated by assessing whether it benefits from additional contextual information in sentences that was not the result of simple word-level associations. The remaining experiments aimed to examine several current models of RH language processing; specifically, they examined the applicability of the coarse-coding hypothesis (Beeman, 1993) and the integrative processing model (Federmeier, 2007) to RH sentence processing. The combined results of the four experiments lead to several conclusions. Firstly, this series of investigation consistently demonstrated that the RH does display a sensitivity to message-level processing that appears to be at least equivalent to that of the LH. This conclusion is uncommon in the normal-behavioral literature, but is consistent with evidence produced by other methodologies. Secondly, the coarse-coding hypothesis is insufficient in explaining RH language processing at the sentential level. Although there is considerable evidence in support of the coarse-coding model of RH processing of individual words, the findings of the present investigations do not support its applicability beyond this level. Thirdly, the integrative/predictive distinction between RH/LH language processing also appears to have limited applicability beyond sentence fragments and may instead be reflective of higher-level processing differences (e.g., wherein the RH may utilize a para-linguistic situation-model processing method whereas the LH may rely purely on a linguistic mechanism). Based on these conclusions, the present series of investigations appears to have resolved the inconsistent finding previously prominent in normal-behavioral literature and goes some way in determining the applicability of current models of RH language processing.

Full text
Abstract:
This study investigated the effects of interference from a center stimulus on the recognition of faces presented in each visual half-field using the tachistoscoptic presentation. Based on prior studies, it was hypothesized that faces would be recognized nnre accurately based on outline features when presented to the Left visual field - Right hemisphere and on inner features for the Right visual field - Left hemisphere. It was also hypothesized that digits presented at center fixation would interfere most with the recognition of the inner details of faces presented to the right hemisphere, since recognizing both faces and digits requires high-frequency spectral analysis (Sergent, 1982b).Each stimulus was cinposed of either a number or a blank at center fixation and a face placed either to the left or right of fixation. The results indicated no performance differences due to the visual field of presentation. Recognition was most accurate when no center stimulus was present, and recognition of outer details was more accurate than recognition of inner details. Subjects tended to use top-to--bottan processing for faces in both visual fields.

Abstract:
This dissertation explores historical and contemporary occurrences of glossolalia or 'speaking in tongues', the production of a series of phonetically transcribable language-like but generally, non-cognitive sounds in a variety of (primarily religious; settings. The main issues are why some are susceptible to glossolalia, some may learn it, some crave the ability but cannot do so, and others are repelled. Divided into three parts, Part I of the dissertation considers the phenomenon of glossolalia itself and moves on to historical and cross-cultural contexts, relating glossolalia to that other realm often described as divine or mystical or supernatural or, as here, paranormal. While vocalizations of various kinds seem common to states of religious ecstasy cross-culturally, as a particular kind of vocalization (which need not occur in ecstasy) giossolaiia seems to be largely confined to, and has acquired a special significance in, Christianity. Further, it is regarded by modern Pentecosta1ists as a rite of passage known as a Baptism of the Holy Spirit which gives access to additional paranormal gifts: powers of wisdom, knowledge, prophecy, healing, exorcism. Part II examines theological, linguistic, and anthropological perspectives, and focuses on: the hostile attitudes of ecclesiastical orthodoxies towards glossolalia and the claims of glossolalists; the non-cognitive nature of glossolaliia despite the claims of Pentecostalists (albeit glossolalia may be a reiigious or 'praise' language) that glossolalia is cognitive and may be interpreted; the concept of taboo in its double sense of forbidden 'because dangerous/therefore attractive'; the validity of that basic assumption of social science, the psychic unity of mankind, in relation to intuitions of the dual nature of human personality and scientific knowledge of the nature and functions of the two hemispheres of the human brain. Giving particular attention to the cultural aetiology of glossolalia, especially in relation to authority, Part III analyses a series of interviews with, and C.L.E.M. tests of, glossolalists, would-be glossolalists and others, relating the results to present knowledge concerning the nature and functions of the Right and Left hemispheres of the human brain. While most people everywhere, responding to the requirements of their cultures, tend to activate their Left hemispheres, the research suggests that, in general, access to the paranormal, supernatural, or divine seems to be a function of the Right hemisphere, and in particular, that glossolalists tend to be Right hemisphere dominant.

Abstract:
AbstractObjective: Surgical revascularization for moyamoya disease (MMD) prevents cerebral ischemic attack by improving cerebral blood flow (CBF) and could also reduce the risk of re-bleeding in hemorrhagic-onset patients. We sought to clarify the cerebral hemodynamic changes in the acute stage after revascularization surgery for adult MMD.Materials and methods: The present study includes 54 consecutive adult patients with MMD (21–76 years old, 43.1 average), undergoing superficial temporal artery-middle cerebral artery anastomosis with indirect pial synangiosis on 65 affected hemispheres. We prospectively performed single-photon emission computed tomography (SPECT) at postoperative day (POD) 1 and 7 of 65 surgeries. Perioperative management was conducted with strict blood pressure control (100–130 mmHg) and minocycline hydrochloride administration.Results: The outcome of 65 surgeries was favorable except for one (1.5%), which manifested as delayed intracerebral hemorrhage due to local hyperperfusion. The postoperative SPECT revealed the characteristic CBF improvement pattern with transient local hyperperfusion (POD1) and subsequent distribution of CBF in wider vascular territory (POD7) on 37 hemispheres (56.9%, 37/65).Conclusion: The revascularization surgery is a safe and effective treatment for adult MMD, while transient local hyperperfusion should be strictly managed by intensive perioperative care.

Abstract:
In this paper, we propose a novel neural network model, called bi-hemispheres domain adversarial neural network (BiDANN), for EEG emotion recognition. BiDANN is motivated by the neuroscience findings, i.e., the emotional brain's asymmetries between left and right hemispheres. The basic idea of BiDANN is to map the EEG feature data of both left and right hemispheres into discriminative feature spaces separately, in which the data representations can be classified easily. For further precisely predicting the class labels of testing data, we narrow the distribution shift between training and testing data by using a global and two local domain discriminators, which work adversarially to the classifier to encourage domain-invariant data representations to emerge. After that, the learned classifier from labeled training data can be applied to unlabeled testing data naturally. We conduct two experiments to verify the performance of our BiDANN model on SEED database. The experimental results show that the proposed model achieves the state-of-the-art performance.

Full text
Abstract:
Evidence from studies requiring the recognition and discrimination of facial and letter stimuli suggests that the right and left cerebral hemispheres are more sensitive to low and high spatial frequencies, respectively. More direct tests requiring the detection of simple sinusoidal gratings have yielded inconclusive findings with some supporting hemispheric asymmetries and others failing to do so. These studies using sinusoidal gratings have used small n terms of 2 or 3, have not controlled eye movements, and in some cases have confounded hemiretina with hemispheric stimulation. Therefore, in the present study we investigated hemispheric and hemiretinal sensitivity to a low (0.8-cycle/deg) and a high (8.7-cycles/deg) spatial frequency grating in 8 observers. To minimize eye movements, the gratings were randomly presented for 100 ms, 1.4 deg from a central fixation in the right, left, upper, or lower visual fields. The right and left eye of each observer was tested during each of two sessions using a criterion-free spatial forced choice procedure. No evidence for asymmetric sensitivity to either spatial frequency was found between the right and left visual fields or for the nasal and temporal hemiretina.

Abstract:
Brain Computer Interface (BCI) have developed applications to identify different degrees of cortical activation in different circumstances in humans. This study implemented a BCI system for the analysis of neurological biosignals for studies in Neuropsychology. The acquired information used OpenBCI hardware elements and software to visualize in real time the brain electrical activity set in voltage and frequency parameters. The web application developed allowed visual monitoring of the brain electrical activity of each electrode, the different frequency bands, the averages between cerebral hemispheres and the activation of a servomotor. The distribution of the channels made it possible to obtain the Theta, Alpha, Beta and Gamma brain rhythms in alert and relaxed states with eyes open as well as closed.

Abstract:
Introduction: Vascular diseases are the leading cause of death in the world. Although major advances in neuroimaging and stroke treatment have contributed to a decrease in mortality, strokes occupy second place in the list. Case report: A 75-year-old man is admitted to emergency with an altered neurological examination: right hemiplegia, Broca’s aphasia and dysphagia. Conscience was preserved. Computed tomography (CT) was performed, which showed the radiological finding of hyperdense MCA sign, confirming the diagnosis of ischemic stroke with involvement of the left middle cerebral artery branch. The treatment, in this case, was outside the criteria for thrombolytics. Discussion: Irrigation of the brain is done by Willis polygon. One of the essential branches is the medium cerebral artery (MCA), the most important termination of the internal carotid arteries, responsible for blood supply of the dorsolateral hemifacial of both cerebral hemispheres, irrigating the frontal, parietal and temporal lobes. The imaging exam in suspected cases of stroke focuses on confirming its diagnosis and etiology, location of the lesion, extent of ischemic evolution, therapeutic treatment and prognosis. CT is the main modality of neuroimaging for stroke and an important radiological finding is the hyperdense artery sign, which is more common in MCA and demonstrates an evolving or impending infarction and is secondary to a plunger housed in this vessel. Therefore, it is an important early tomographic sign of ischemic stroke found on non-contrast blood CT. Conclusion: Ischemic stroke is the most common etiology among strokes. The diagnosis must be based mainly on anamnesis and image exam, such as a CT scan. The CT performed helps to guide treatment, prognosis and clinical evolution. Finally, the recognition of the hyperdense MCA sign, found in the first 6 hours, is also extremely helpful for stroke classification.

Abstract:
Introduction: The investigation of hemorrhagic demyelinating cerebral lesions is challenging with diverse etiologies. We report a case of varicella zoster virus (VZV) infection with prominent hemorrhagic demyelinating component and systemic thrombosis. Objectives: Describe a case of hemorrhagic demyelinating lesions and systemic thrombosis secondary to varicella zoster central nervous system infection. Case report: A 45-year-old man presented with a one-week history of left leg strength loss associated with pyramidal liberation on the left side. Brain MRI showed two expansive hemorrhagic lesions, in the frontoparietal lobe and in the cingulate gyrus region. There were T2/FLAIR hypersignal in the subcortical area of both cerebral hemispheres and in the cervical cord, suggestive of demyelination. His arterial magnetic resonance imaging with vessel wall imaging showed focal tapering on the pial branches of the middle cerebral artery, but his digital angiography showed no abnormalities. The lumbar puncture had 8 cells, (lymphocyte predominance), 52 proteins/ dL, and 53 mg/dL of glucose. In two days, he developed a left side hemiplegia associated with seizures and pulmonary thromboembolism, demanding lung mechanical thrombectomy and anticoagulation. He had a positive lupus anticoagulant and a positive VZV IgG in the cerebrospinal fluid associated with positive oligoclonal bands. He received intravenous acyclovir with complete resolution of the symptoms. Conclusion: The clinical manifestations of VZV infection are wide, and we should suspect of this infection in patients with central nervous system demyelinating lesions, even without other skin lesions.
