Event-Related Potentials in Patients with Brain Tumors and Traumatic Head Injuries

Research in cognitive psychophysiology has shown that event-related potentials (ERPs) reflect specific processes of human information processing (Gaillard and Ritter 1983). We have carried out ERP recording and neuropsychological testing in patients with brain tumors and traumatic head injuries in order to obtain some information about the neuroanatomical substrate of ERPs and about the utility of ERPs for the evaluation of cognitive impairment.
