Encoding-related deficits. Regions showing group differences during the encoding phase of working memory (WM). Precise coordinates are listed in the top panel of table 2. All foci shown were identified within the WM-related areas constrained space using the assumed hemodynamic response function (HRF) analysis (see Methods). Time courses were extracted for each region using an unassumed HRF approach to facilitate visual inspection of group differences across trial epochs. The approximate relevant encoding period of the time course is marked using the gray box. Time courses for control subjects are shown using circles whereas time courses for patients are shown using triangles.
