Biography

The Coley laboratory investigates neural populations and dynamics associated with depressive-like behaviors. We apply integrative approaches such as in vivo 2-photon calcium imaging to measure neural activity and population dynamics, and ex vivo electrophysiology to record synaptic properties. We utilize optogenetics techniques to selectively activate neural circuits and assess the response within specific neurons. We also use computer-based tracking systems to monitor behavioral tasks and apply machine learning methods to uncover the relationship between neural activity and behavior. Additionally, we use computational models to further understand neuronal population function in higher-order processing regions.

Biography

Chuchu Zhang, Ph.D. is an Assistant Professor in the Department of Physiology in the David Geffen School of Medicine at UCLA. She received her B.S. in Biochemistry from the Hong Kong University of Science and Technology. She then received her Ph.D. in Neuroscience from the University of California, San Francisco, where she worked with Dr. David Julius studying pain-producing toxins from venomous animals. Her work utilized these natural toxins to identify and manipulate pain-related signal transduction machineries in sensory neurons. Afterwards, she carried out her postdoctoral fellowship with Dr. Stephen Liberles at Harvard Medical School, where she started her independent trajectory to study nausea. She focused on a brain structure, the area postrema, which mediates nausea responses to several visceral threats. Her work has uncovered fundamental aspects of the area postrema, including cell types, receptors, and nausea-related neural circuits. The Zhang Lab opens in September 2023 at UCLA.
