Brainwaves

What does a brain look like in a patient with a functional movement disorder? Pretty normal, it turns out. But beneath the normal anatomy is a storm of aberrant signaling. Dr. Mark Hallett, Chief of the Human Motor Control Section of the NIH, describes the underlying neurophysiology in this spectrum of disorders. Produced by James E. Siegler. Music by Damiano Baldoni, Kevin MacLeod, Ondrosik, and the Philadelphia String Quartet. Voiceover by Erika Mejia.
