Eric Wassermann, M.D., Staff Clinician
Dr. Wassermann received his B.A. from Swarthmore College, his M.A. from the University of Pennsylvania where he studied behavioral neurophysiology with C.R. Gallistel, and his M.D. from New York Medical College. After a Neurology Residency at the Boston City Hospital, he came to the NINDS as a postdoctoral fellow in the Human Motor Control Section, where he studied the physiology of the motor cortex and the control of voluntary movement. In 1997, he established the Brain Stimulation Unit to extend the same techniques and concepts to investigating the prefrontal cortex and the control of emotion and action. He is the recipient of numerous awards, including the Pfizer Visiting Professorship in psychiatry, two NIH Director's Awards, and the US Public Health Service Outstanding Service Medal. Dr. Wassermann’s clinical interests include behavioral neurology, clinical neurophysiology, and chemical casualty care. He directs the clinical activities of the NINDS Cognitive Neuroscience Section and serves as a Senior Medical Advisor to the HHS Assistant Secretary for Preparedness and Response.

Eddy Current Brain Stimulation

Transcranial brain stimulation

We study the physiology of the brain systems underlying executive function and emotional regulation, using noninvasive stimulation and imaging techniques. We are also interested in developing new treatments for patients with frontal lobe (executive) disorders and ways of enhancing cognitive functions in healthy individuals.

Using magnetic stimulation and electrical neuromodulatory techniques and functional MRI, we are investigating the mechanisms of rewarded and emotionally driven behaviors in the human brain. New thrusts include incorporating near infrared spectroscopy into our work in healthy subjects and patients.

We are part of the NINDS Cognitive Neuroscience Section (Jordan Grafman, Chief) and collaborate with them on the natural history and pathophysiology of frontotemporal dementia and other frontal lobe. Other clinical collaborations with the Cognitive Neuroscience Section include the evaluation of war fighters with traumatic brain injury.
