Dr. Jun Maruta conducts research on brain mechanisms for spatial orientation and balance with the purpose of better understanding and improving human health.
The sense of balance, or equilibrium, is mediated by the input to the brain from the skull-embedded motion sensors in the inner ear called the vestibular organs. In the brain, the vestibular input is combined with other inputs, such as vision and those from sensors in muscles and joints. The combined information is used to support vision and posture by controlling eye and body movements, as well as create an overall sense of body position and movement in space. Much of these operations are carried out through mechanisms of the brainstem and the cerebellum, and is involuntary. These reflexive mechanisms are normally highly efficient, but their disruptions result in imbalance, dizziness, vision problems, nausea, and concentration problems, which can have devastating consequences in daily life as experienced by patients of ataxia, motion sickness, mal de débarquement syndrome, and other illnesses.
Mount Sinai has played a leading role in stimulating patient care and scientific advancement through vestibular research. Dr. Maruta’s research will identify how the central brain mechanisms process information to produce behavioral consequences that support balance, as well as how these mechanisms can be maladapted to disrupt normal balance.

Brain Mechanisms for Spatial Orientation and Balance
Jun Maruta’s research interests are in “smart” behaviors that feature the capacity to anticipate changes in the organism’s relationship to the environment as well as abnormal conditions that disrupt that capacity.
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.

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.
