The present study examined the biological correlates of electrodermal activity in 63 patients with DSM-III diagnosed chronic schizophrenia. Subjects were administered a battery of neuropsychological tests sensitive to temporal lobe, frontal lobe, and overall brain functioning. Brain morphology was evaluated by calculating the size of the lateral ventricles, measuring the width of the third ventricle, and rating the extent to which cortical sulci were visible. Electrodermal hyporesponsiveness was associated with impaired performance on tests that assessed temporal lobe functioning. No association was found between the brain morphology indices and electrodermal activity.
