Distinct contributions by frontal and parietal cortices support working memory

Distinct contributions by frontal and parietal cortices support working memory

Abstract Although subregions of frontal and parietal cortex both contribute and coordinate to support working memory (WM) functions, their distinct contributions remain elusive. Here, we demonstrate that perturbations to topographically organized human frontal and parietal cortex during WM maintenan...
