Brain activity during the working memory task. a, Brain areas showing main effect of the working memory task revealed by voxelwise ANOVA (corrected p < 0.01). To illustrate task-induced activation and deactivation, brain activities within these areas at the 3-back level are shown. b, Cognitive load modulated deactivation in the PCC/PCu region. (c) The PCC/PCu deactivation was significantly correlated with 3-back working memory task performance.
