Activation correlated with recognition memory by condition. The top row shows regional activation for the main effect of recognition relative to baseline (i.e, the NEW stimulus). Subsequent rows reveal regional activation during recognition of GO, NO-GO and Instructed (INS) stimulus items relative to a baseline. The most prominent and consistently activated region across conditions was the occipitoparietal region. Activation was also noted in varying degrees in dorsolateral and ventrolateral prefrontal cortex and posterior parietal regions. Linear increases in activation reflecting magnitude differences across conditions were also noted (Instructed > NO-GO > GO). The regional increases were centered in the precuneus, superior and inferior frontal gyrus and right superior parietal regions (results shown in panel A. at P < .001 and in panel B. at P < .000001). The insert shows bilateral increases in the posterior parahippocampus and hippocampus.
