About the Lab
The Functional and Cognitive Neurophysiology laboratory, led by Dr. Sameer Sheth, focuses on the study of human decision-making and cognition, as well as on the development of novel therapies for neuropsychiatric disorders. To accomplish these goals, we take a two-fold approach.
- First, we work with neurosurgical patients undergoing deep brain stimulation (DBS), epilepsy monitoring, and other procedures that require the placement of intracranial electrodes. We use single-neuron and field potential recordings as well as stimulation to understand the circuitry underlying complex cognitive functions such as controlled decision-making, memory formation, and emotional regulation.
- Second, we develop and refine neuromodulatory treatments for refractory neurological and psychiatric disorders such as obsessive-compulsive disorder (OCD), depression, and many others. These disorders often arise from dysfunction in the same circuits mentioned above.
Thus the two efforts advance synergistically, with a constant back-and-forth flow of ideas. Because of the multi-disciplinary nature of this work, the lab interacts closely with many other disciplines, including Neuroscience, Psychiatry, Neurology, Computer Science, Engineering, Machine Learning / Artificial Intelligence and others.
