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.
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 2018 and/or 2019: 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.

Mount Sinai's faculty policies relating to faculty collaboration with industry are posted on our website. Patients may wish to ask their physician about the activities they perform for companies.
Physicians who provide services at hospitals and facilities in the Mount Sinai Health System might not participate in the same health plans as those Mount Sinai hospitals and facilities (even if the physicians are employed or contracted by those hospitals or facilities).
Information regarding insurance participation and billing by this physician may be found on this page, and can also be obtained by contacting this provider directly. Because physicians insurance participation can change, the insurance information on this page may not always be up-to-date. Please contact this physician directly to obtain the most up-to-date insurance information.
Insurance and health plan networks that the various Mount Sinai Health System hospitals and facilities participate in can be found on the Mount Sinai Health System website.
