Background and purpose. The aim of this study was to determine if brain lesions located in the parieto-temporo-occipital area (PTO) are associated with such disorders of body scheme as autotopagnosia, finger agnosia and right-left disorientation, if these disorders result from damage to the left or right brain hemisphere, and if other cognitive disorders may be influencing test results in studi...

Introduction :Today there is general awareness of the potential damage to the heart in left- sided (more than in rightsided) breast cancer radiotherapy.     Material & Method: Historical changes in tumor and heart doses are presented here along with the impact of different RT techniques and volumes. Results: Individual and pharm...

The hemi-inattention syndrome was studied in 15 right-handed adults, 12 men and 3 women. One patient had a pontic-mesencephalic lesion, 3 had right hemisphere damage, 7 had left-hemisphere lesion and 4 had bilateral lesions. All lesions were confirmed by CT-scan. Different criteria of hemi-inattention were used. All patients presented extinction, inattention and in 13 visuomotor akinesia; 5 of ...

a b s t r a c t introduction:we investigated differential role of cortical and subcortical regions in verbal and non-verbal sound processing in ten patients who were native speakers of persian with unilateral cortical and/or unilateral and bilateral subcortical lesions and 40 normal speakers as control subjects. methods: the verbal tasks included monosyllabic, disyllabic dichotic and diotic tas...

We studied a patient with right parietal damage for whom tactile stimuli on the right/ipsilesional hand (projecting to the intact left hemisphere) were extinguished from awareness during double simultaneous stimulation, when his right hand was positioned in the left/contralesional space. This demonstrates the role of an egocentric spatial reference frame in attention that can determine awarenes...

Depression is characterized by the functional insufficiency of both left and right hemispheres. Patients who respond to antidepressants are characterized by a relatively higher left hemisphere activity in comparison to non-responders, and successful treatment with antidepressants increases left hemisphere activity. Left hemisphere is responsible for the goal-oriented behavior that includes sear...

Right hemisphere dominance in face processing is well established and unilateral right inferior temporo-occipital damage can result in prosopagnosia. Here, we describe a 21-year-old right-handed woman with acute impairment in face recognition that selectively concerned unfamiliar faces, following a focal left lateral temporo-occipital venous infarct. She was severely impaired in discerning that...

We investigated (1) how focal brain-injured patients describe causal events (causal verb like “push” and the instrument of the action like “the stick”) in speech and co-speech gestures and (2) whether gestures compensate for their impaired verbalization. 16 left hemisphere damaged (LHD), 16 right hemisphere damaged (RHD) and 14 controls were asked to describe causal events (22 video clips). The...

In three experiments, healthy young participants listened to stories promoting inferences and named inference-related test words presented to the right visual field-Left Hemisphere (rvf-LH) or to the left visual field-Right Hemisphere (lvf-RH). Participants showed priming for predictive inferences only for target words presented to the lvf-RH; in contrast, they showed priming for coherence infe...
