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.


Research Interests:

Eddy Current Brain Stimulation

Transcranial brain stimulation

Ongoing clinical studies include the evaluation of warfighters with traumatic brain injury and blast exposure. We are currently conducting Phase IV of the Vietnam Head Injury Study, an in-depth cognitive and lesion anatomy evaluation of several hundred brain injured veterans and combat-exposed controls. Some of our work is sponsored by the Center for Neuroscience and Regenerative Medicine at the Uniformed Services University of the Health Sciences (USUHS).

We study the brain systems underlying learning, executive function, and behavioral regulation, using noninvasive stimulation and imaging techniques an innovative behavioral tools. Our main clinical interest is in the physiological and neuroanatomical basis of excess mental and physicial fatigue after brain injury. In particular, we are interested in how lesions of the dopamine reward system and other monoaminergic projections to the forebrain interfere with human behavior. 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 noninvasive brain stimulation techniques and structural and functional MRI, and MR spectroscopy, we are investigating the mechanisms of rewarded behaviors, for example, learning and sustained effort, in the human brain. New thrusts include incorporating near infrared spectroscopy into our work in healthy subjects and patients.
