Background: Neuroimaging studies of schizophrenic subjects performing working memory
(WM) tasks have demonstrated a relative hypoactivity of prefrontal cortex compared with
normal subjects. Methods: Using functional magnetic resonance imaging (fMRI), we
compared dorsolateral prefrontal cortex (DLPFC) activation in 12 schizophrenic and 10
normal subjects during rewarded performance of a WM task. Subjects performed a modified
version of the Sternberg Item Recognition Paradigm (SIRP), a continuous performance …
