- ASSISTANT PROFESSOR | Neuroscience
Tristan Shuman is an Assistant Professor of Neuroscience at the Icahn School of Medicine at Mount Sinai. His research focuses on how epilepsy leads to cognitive deficits and how these deficits can be rescued using interneuron transplantation in rodent models. His lab uses in vivo calcium imaging with miniature microscopes as well as electrophysiology to investigate the precise network alterations that produce seizures and cognitive deficits in epileptic mice. Dr Shuman obtained his PhD in Experimental Psychology from University of California, San Diego, where he examined how addiction-related memory ensembles contributed to cocaine drug seeking. Prior to joining the faculty at Mount Sinai, Dr Shuman was a postdoctoral fellow at the University of California, Los Angeles where he examined network alterations in epileptic mice.

Cognitive Deficits Associated with Temporal Lobe Epilepsy
Epilepsy is a debilitating disorder that affects over 3 million Americans, with 30% of patients unresponsive to anti-epileptic drugs and often resorting to large resections of the brain. Therefore, it is critical to develop new therapeutic interventions to suppress seizures and cognitive deficits in epilepsy. My lab uses state of the art recording and manipulation techniques to examine how abnormal circuit processing leads to seizures and cognitive deficits in epilepsy and to understand how seizures and cognitive deficits can be suppressed with novel interventions. We use in vivo calcium imaging with miniature microscopes as well as in vivo electrophysiology with silicon probes to examine how the epileptic brain is altered in mice.
Mechanisms of seizure and cognitive rescue using interneuron precursor transplantation
Stem cell transplantations offer a unique opportunity to treat the underlying cause of epilepsy by replacing the interneurons lost during epileptogenesis. Transplantation of embryonic interneuron precursors from the medial ganglionic eminence (MGE) into the hippocampus of epileptic mice dramatically reduces seizures and rescues performance on the Morris water maze spatial memory task. These transplanted interneurons integrate and form mature, functional connections, but there is significant debate about how they control seizures and cognitive deficits. My lab investigates the mechanisms of seizure and cognitive rescue by examining how transplanted interneurons reshape hippocampal circuits using both in vivo electrophysiology and calcium imaging.
Open source miniature microscopes
Miniscope.org is an online open-source platform for developing and using miniature microscopes primarily used for calcium imaging in small rodents. As a primary developer and contributor to this effort, my lab is continuing to develop new innovations of this technology and sharing them with the neuroscience community.
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.

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.
