David Sulzer is an American neuroscientist and musician. He is a professor at Columbia University Medical Center in the Departments of Psychiatry, Neurology, and Pharmacology. Sulzer's lab investigates the interaction between the synapses of the cerebral cortex and the basal ganglia, including the dopamine system, in habit formation, planning, decision making, and diseases of the system. His lab has developed the first means to optically measure neurotransmission, and has introduced new hypotheses of neurodegeneration in Parkinson's disease, and changes in synapses that produce autism and habit learning. Under the stage name Dave Soldier, he is known as a composer and musician in a variety of genres including avant-garde, classical, and jazz. He is the author of the soon to be published book "Music, Math, and Mind" (Columbia University Press).
