Synaptic Transmission Section - Division of Intramural Research

 Ling-Gang   Wu  M.D., Ph.D., Senior Investigator

Dr. Wu received his M.D. in 1985 from Second Military Medical College, Shanghai, and his Ph.D. in neuroscience in 1994 from Baylor College of Medicine, where he worked with Peter Saggau studying the role of presynaptic voltage-dependent calcium channels in controlling transmitter release. From 1994 to 1996 he did postdoctoral training with William J. Betz at the University of Colorado Medical School, where he studied the kinetic regulation of endocytosis at frog neuromuscular junctions using FM dye imaging. From 1996 to 1999 he a second postdoctoral fellowship with Bert Sakmann at the Max Planck Institute in Heidelberg, Germany, where he identified calcium channel types and studied the presynaptic mechanisms underlying short-term synaptic depression at a giant nerve terminal, the calyx of Held in rat brainstem. From 1999 to 2003 he was an assistant professor at Washington University in St. Louis, where his laboratory applied capacitance recording techniques to study regulation of the kinetics of endocytosis at the calyx of Held. Dr. Wu joined NINDS as an investigator in 2003 and was promoted to senior investigator in 2007. His laboratory is using electrophysiological, imaging, as well as biochemical and molecular biological techniques, to investigate the cellular and molecular mechanisms underlying generation and regulation of endocytosis and synaptic plasticity at the calyx-type synapse.

Research Interests

Neurons communicate with each other via chemical synaptic transmission. Regulation of the strength of synaptic transmission plays essential roles in many physiological and pathological processes, such as control of neuronal network outputs, neuronal development, learning and memory, and neurological diseases. It remains poorly understood how synaptic strength is controlled at nerve terminals. Filling this gap of knowledge is the goal of the Synaptic Transmission Unit.
