Research Summary:

Prof. Petrides's research interests lie in the area of neuropsychology/cognitive neuroscience and involve the analysis of the functions of the frontal, temporal, and parietal neocortex and related subcortical neural structures. This is pursued by investigations of the cognitive impairments observed in patients with focal brain lesions, by the analysis of the behavioral effects of lesions in animals, and functional neuroimaging studies with PET and EMRI.
