Control of transmitter release by electrical and biochemical signaling.

Research Summary:

The Levitan lab combines novel microscopy approaches, electrophysiology and molecular biology to learn how electrical activity, intracellular signaling and therapeutic drugs (e.g. antipsychotics and antidepressants) control neuronal activity and release of transmitters at nerve terminals and dendrites. Projects are split between two experimental systems: Drosophila, which is well suited for genetic manipulation of identified neurons, and mammalian brain slice, where dopamine and serotonin neurons are studied with multiphoton microscopy and dynamic clamp. Recent studies have focused on the delivery of single vesicles and a kinase to release sites, action potential-independent release and long-term control of neuronal excitability.
