For each area, we tested the left and right hemispheres independently and compared these performances with the bilateral frontal lobe as well as the activity across all regions.
we examined the primary visual areas (left and right occipital lobe), speech and language processing areas (left temporal) and verbal memory (right temporal), sensory perception (left parietal) and integration (right parietal), language related movements (left frontal) and nonverbal functioning (right frontal).
