The Functional and Cognitive Neurophysiology laboratory, led by Dr. Sameer Sheth, focuses on the study of human decision-making, behavior, and cognitive processes.  We use a combination of imaging and intracranial electrophysiology to investigate structural and functional relationships in the human brain. Neurosurgical procedures such as deep brain stimulation (DBS), epilepsy surgery, and brain tumor resection often require detailed imaging and electrophysiological recordings before, during, and after surgery. We utilize these unique opportunities to study the human brain and behavior in health and disease states.
