Donald J. Weisz, PhD

Before joining the faculty at Mount Sinai in 1992, Dr. Weisz was an Assistant Professor in the Department of Psychology at Yale University (1981-1988) and an Associate Professor in the Departments of Behavioral Neuroscience and Neurosurgery at the University of Pittsburgh (1988-1992). At Pittsburgh he served for two years as Assistant Chairman of the Department of Behavioral Neuroscience. Since coming to Mount Sinai in 1992, Dr. Weisz has been Director of  Intraoperative Monitoring in the Department of Neurosurgery. He has been the principal or co-investigator on grants since 1977. Presently, he is co-investigator on an NIH grant, "Cerebral Function after Hypothermic Circulatory Arrest."

Dr. Weisz and his staff monitor neurophysiological activity of patients undergoing surgeries of the brain and spine that place the nervous system at risk. Responses are elicited in the nervous system by stimulation of both motor and sensory systems. In addition, Dr. Weisz monitors the activity of single cells in the brain during surgeries for the implantation of deep-brain stimulating electrodes in patients with movement disorders. The single cell recordings are made near and in the target structures to aid the neurosurgeon in refining the site of implantation.
