Cortex Lesions (image) University of Iowa Health Care Caption The image shows the overlap of lesions for eight subjects superimposed on a template brain -- red indicates maximum overlap (seven subjects) and dark blue is minimum overlap (one subject). The patient group was selected for lesions that include frontopolar cortex, but the lesions almost invariably extended outside to other parts of anterior prefrontal cortex.
