AbstractThe present study investigated the ability of cerebrovascular accident (CVA) patients to perceive emotions portrayed by realistic stimuli. Statistical analyses demonstrated that CVA patients with damage to either the right or left cerebral hemisphere performed, on average, as well as controls did in perceiving emotions. However, a case study of one patient suggested that there may be a subset of CVA patients with right parieto-occipital damage who have deficits in the perception of negative emotions. The performance of this participant also indicated that deficits in emotion perception are ameliorated to some extent when patients are provided with realistic, complex stimuli that include a range of auditory and visual cues.

Unfamiliar Faces

Repetition priming (RP) is the ability to recognize a stimulus more rapidly as a result of prior exposure to the item. Recent research examining the neuroanatomical basis of this effect has demonstrated RP for familiar faces presented to the right but not to the left cerebral hemisphere. Extending this line of enquiry, the current research considered whether similar effects emerge when unfamiliar faces are the stimuli of interest. Using a divided-visual-field methodology, RP for unfamiliar faces in the left and the right hemispheres was assessed. The results revealed that RP: (i) only emerges in the right hemisphere; (ii) is evident regardless of whether the lateralized presentation of unfamiliar faces occurs at study or at test and (iii) occurs only when hair is cropped from the faces. The theoretical implications of these findings are considered.

Under conditions of monocular unihemispheric projection of word stimuli to the brain, 10 normal Ss uniformly showed superior word recognition ability of the left, as opposed to the right, cerebral hemisphere. Left-hemisphere recognitions were significantly more frequent than right-hemisphere recognitions for both eyes, but the extent of left-hemisphere superiority was significantly greater for the left eye. The results support the hypothesis that words projected to the right hemisphere traverse a less efficient route to the language centers of the left hemisphere.

ABSTRACT The role of the right cerebral hemisphere (RH) associated with semantic priming effects (SPEs) must be better understood, since the consequences of RH damage on SPE are not yet well established. Objective: The aim of this article was to investigate studies analyzing SPEs in patients affected by stroke in the RH through a systematic review, verifying whether there are deficits in SPEs, and whether performance varies depending on the type of semantic processing evaluated or stimulus in the task. Methods: A search was conducted on the LILACS, PUBMED and PSYCINFO databases. Results: Out of the initial 27 studies identified, 11 remained in the review. Difficulties in SPEs were shown in five studies. Performance does not seem to vary depending on the type of processing, but on the type of stimulus used. Conclusion: This ability should be evaluated in individuals that have suffered a stroke in the RH in order to provide treatments that will contribute to their recovery.

Stroke or cerbreovascular accidents are the leading cause of morbidity and mortality across the world.Infact the third leading cause after heart diseases and cancer.Strokes can be classied broadly as ischemic and hemorrhagic which accounts for 80% and 20% of the total cases.The prognosis of CVA depends on the type and its fast and appropriate management.A 50 year old male patient who is k/c/o type 2 diabetes mellitus,hypertension and hypercholistremia was admitted to the inpatient department of Sri Jayendra Saraswathi Ayurveda College and Hospital,Chennai on 20.01.2020 with the conrmed diagnosis of stroke(CVA) having both infarct and hemorrhage.The chief complaints were difculty in walking without support,reduced strength, stiffness and heaviness in the right hand and leg, difculty in speech, pain in right shoulder joint and knee joint since 4 months.This condition can be understood as Pakshaghata in Ayurveda.After proper evaluation of the avastha of the patient,Avarana chikitsa along with the Pakshaghata chikitsa was adopted in this case,Signicant improvements were observed on various subjective and objective parameters.The patient was discharged after 10 days of treatment with oral medications and advised for a follow up after 1 month.

The article deals with the concept of hypnotic metaphor in psychiatry and linguistics and explores its application in the situation of public teaching discourse. The right-hemisphere mechanisms of perception are considered in order to detect sensory images, represented in the universal object code, since the processes of mastering the facts, which are based on similarity, adjacency, imagery, take place in the right hemisphere. The connection of mirror neurons with metaphorical thinking is assumed. The classification of metaphor types in psychotherapeutic literature is given. The article analyzes the performance of modern speaker-coaches, given as lectures, trainings, conversations and designed to effectively change the emotional mood and categorical constructs of listeners. Otherwise, listeners simply will not buy tickets for these events. It is concluded that modern lecture trainings are a kind of group psychotherapy session. Information is fed in a ‘live stream’ of right-hemisphere mechanisms involving mirror neurons. Coach rhetoric is a system of metaphors that are archetypes of consciousness and are part of the basic layer of the conceptual framework.

Abstract Shapes

The purpose of the present study was to investigate the nature of the relationship between gross-motor, eye-hand coordination and hemispheric specialization in normal right-handed children. Participants were 30 children, 75–99 mo. 15 boys and 15 girls performed a gross-motor eye-hand coordination task (a controlled, continuous one-handed ball bounce) and a test of hemispheric specialization. A backscreen tachistoscopic projection system was used to present letters and abstract shapes to left and right visual hemifields. A multivariate analysis of variance yielded a significant main effect for eye-hand coordination but not for sex. Follow-up analyses indicated that speed and accuracy of responses to verbal and spatial stimuli presented to the left cerebral hemisphere were significantly related to proficiency of eye-hand coordination. Data suggest that certain aspects of hemispheric specialization may be important to gross-motor eye-hand coordination in young children. Since the left cerebral hemisphere is the major control center for movements of the right side, the hemisphere which controls movements of a particular side may also assume the major responsibility for processing information needed to regulate those movements.

Twelve patients with left cerebral hemisphere lesions and 12 with right hemisphere lesions chose, from among four alternatives, the word that was identical in spelling to a sample word (verbal or extraverbal components sufficient to perform task at this level), and chose a synonym of the sample word from among four alternatives (verbal component necessary). The words were presented in unimodal and cross-modal conditions. In the unimodal conditions sample words and alternatives were presented in the same modality (aural or visual); in the cross-modal conditions the sample word was presented in one modality (A or V) and the alternatives in the opposite modality (V or A). The subject responded by pushing a button when he perceived the correct choice. Patients with right-sided lesions had significantly greater response times, and more errors, than patients with left-sided lesions on those items in which the extraverbal component was crucial to successful performance. The converse was true on those items that called for greater facility with the verbal component of language. There were no significant differences between unimodal and cross-modal tasks.

The purpose of the study reported here is to examine the right/left cerebral hemisphere relationships between writing in the extensive mode and writing in the reflexive mode. Preliminary findings suggest that writing which is focused on communicating information already familiar and formulated by the writer, characteristics of extensive composing, is accompanied by greater relative engagement of the left cerebral hemisphere as indicated by lower relative EEG amplitude ratios measured from electrodes placed symmetrically over the left and right temporal areas. Writing which is focused upon discovering meanings, which is tentative and exploratory - characteristics of reflexive composing - is accompanied by greater relative engagement of the right cerebral hemisphere. Traditional instruction has failed because it is “half-brained,” addressing only one of these modes of composing.
