Thalamic glutamate levels as a predictor of cortical response during executive functioning in subjects at high risk for psychosis.
CONTEXT: Alterations in glutamatergic neurotransmission and cerebral cortical dysfunction are thought to be central to the pathophysiology of psychosis, but the relationship between these 2 factors is unclear. OBJECTIVE: To investigate the relationship between brain glutamate levels and cortical response during executive functioning in people at high risk for psychosis (ie, with an at-risk mental state [ARMS]). DESIGN: Subjects were studied using functional magnetic resonance imaging while th...Expand abstract
