TITLE : A profile of cognitive function in Focal Brain lesion
VENUE : CVPR Unit (8th floor of Library Building
DATE : March 24, 2004.
TIME : 3 P.M.
In order to identify the underlying substrates of the attention, working memory, executive function and other memory functions, different patients with focal lesion at different sites of the brain have been studied employing neuro-imaging and neuro-psychological techniques. After identification of the lesion site with the CT-Scan or MRI, the test for the assessment of the nature and degree of impairment of cognitive function, have been employed in different focal lesion groups. The focal lesion involved the frontal, parietal, tempero parietal region of the brain and also the regions of the thalamus, basal ganglia and cerebellum. Lesion in both the right and left hemisphere for almost each of the lobe have been considered. Observation indicated the involvement of different substrates in
the operation of single function and also the dissociation of the related function due to involvement of different substrates.
