Summary of Research Studies:
Studies in our laboratory are dedicated toward understanding the neural basis for spatial orientation in humans and animals, on Earth and in space. Techniques utilized include precise recordings of head, eye, body, and limb movements in three-dimensional space while humans and monkeys perform natural linear and circular locomotion. Also ongoing are behavioral (eye movement) studies on animals and humans utilizing multiaxis vestibular stimulators. Single unit recordings are done in the brainstem and cerebellum of animals performing behavioral tasks or in response to linear and angular acceleration. Multiunit recordings of muscle sympathetic nerve activity are utilized in humans to study vestibulosympathetic reflexes. Also in progress are studies utilizing centrifugation and eye movement recordings of astronauts before, during and after space flight. Studies on treatment of motion sickness in humans are also in progress. Mathematical modeling is an integral part of the approach to describing how neural organizations in the brainstem and cerebellum code spatial orientation.

Industry Relationships
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. Cohen 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.
