- 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.

Physicians and scientists on the faculty of the Icahn School of Medicine at Mount Sinai often interact with pharmaceutical, device and biotechnology companies to improve patient care, develop new therapies and achieve scientific breakthroughs. In order to promote an ethical and transparent environment for conducting research, providing clinical care and teaching, Mount Sinai requires that salaried faculty inform the School of their relationships with such companies.
Dr. Weisz did not report having any of the following types of financial relationships with industry during 2012 and/or 2013: consulting, scientific advisory board, industry-sponsored lectures, service on Board of Directors, participation on industry-sponsored committees, equity ownership valued at greater than 5% of a publicly traded company or any value in a privately held company. Please note that this information may differ from information posted on corporate sites due to timing or classification differences.
Mount Sinai's faculty policies relating to faculty collaboration with industry are posted on our website at http://icahn.mssm.edu/about-us/services-and-resources/faculty-resources/handbooks-and-policies/faculty-handbook. Patients may wish to ask their physician about the activities they perform for companies.
