Is working memory (WM) a unitary construct or is it composed of separable sub-processes with distinct neuroanatomical bases? In line with this latter view, (i) psychiatric and neurological patients often display subtle deficits in specific aspects of WM, and (ii) neurophysiological evidence indicates that WM engages a wide network of regions throughout the brain.To address this question, we designed a WM battery that required participants to maintain the colors and locations of multiple discs over a brief memory delay and report the location of the cued disc. By varying the number of discs to
