Previous research with both brain-damaged and neurologically intact individuals suggests that the right cerebral hemisphere (RH) is superior to the left cerebral hemisphere (LH) at detecting anomalies in objects. The current research assesses whether experience with a category is necessary for this RH advantage to emerge. Participants were taught the diagnostic criteria necessary to categorize ...

The aim of our study was to test for lateralization of magnetic compass orientation in pigeons. Having shown that pigeons are capable of learning magnetic compass directions in an operant task, we wanted to know whether the brain hemispheres contribute differently and how the lateralization pattern relates to findings in other avian species. Birds that had learnt to locate food in an operant ch...

background: as both oral and verbal apraxia are related  to vocal orofacial musculature, this study aimed at identifying brain regions impaired in cases with oral and verbal apraxia. methods:   in  this non-experimental  study,  46  left  brain damaged subjects (17 females)  aged  23–84  years,  were examined  by oral and  verbal apraxia tasks.  impaired  and spared broca’s area, insula, and mi...

This review highlights the importance of right hemisphere language functions for successful social communication and advances the hypothesis that the core deficit in psychosis is a failure of segregation of right from left hemisphere functions. Lesion studies of stroke patients and dichotic listening and functional imaging studies of healthy people have shown that some language functions are me...

short-term visual retrieving processes were investigated in three groups, of schizophernics (n=10), right hemisphere brain damaged (n=10) and a normal grou (n=10) . all of subjects were men and right handed. the study utilized wais (verbal subtests), meaningless syllabuses, retrieve and recall tests and non-verbal patternes retrieve and recall tests. data were analyzed by three factor repeated ...

 Thin-walled energy absorbers are used to reduce accident induced damages. In this study, thin-walled stainless steel structures in quasi-hemisphere geometry were subjected under quasi-static loading with Santam 150KN apparatus. Experimental results were compared with results of numerical simulations by LS-DYNA and it was shown that there is a good agreement between experimental and numerical r...
