Characterizing anterior cingulate activation in chronic schizophrenia: a group and single‐subject fMRI study

Objective:  Functional abnormalities of the dorsal anterior cingulate (dAC) region have been emphasized in schizophrenia, particularly in relation to cognitive deficits. In this study, we sought to further evaluate the notion of dAC hypofunction in chronic schizophrenia patients using a cognitive task specifically designed to activate this region, enabling both group and single‐subject level analyses.
