From Pecking Order to Ketamine – Neural mechanisms of social and emotional behaviors

Seminars

Overview
You are invited to attend a seminar hosted by the A*STAR Institute of Molecular and Cell Biology on From Pecking Order to Ketamine – Neural mechanisms of social and emotional behaviors.

Abstract:
Emotions and social interactions color our lives and shape our behaviors. Using animal models and engineered manipulations, we aim to understand how social and emotional behaviors are encoded in the brain, focusing on the neural circuits underlying dominance hierarchy and depression. This lecture will highlight our recent discoveries on how downward social mobility leads to depression; how ketamine tames depression by blocking burst firing in the brain’s anti-reward center; and, how glia-neuron interaction plays a surprising role in this process. I will also present our recent work on the mechanism underlying the sustained antidepressant activity of ketamine and its brain region specificity. With these results, we hope to illuminate on a more unified theory on ketamine’s mode of action and inspire new treatment strategies for depression.

Biography:
Hailan Hu is Professor and Director of School of Brain Science and Brain Medicine at Zhejiang University. She received a BA in Biochemistry from Beijing University and a PhD in neuroscience (with Corey Goodman) from UC Berkeley. After a postdoc training with Roberto Malinow at CSHL, she joined the faculty of Institute of Neuroscience, Chinese Academy of Sciences. Since 2015, she has been professor at Zhejiang University. Her laboratory seeks to understand how emotional and social behaviors are encoded and regulated in the brain, with a main focus on the neural circuitry underlying depression and social dominance. Her team has identified the neural mechanism underlying the winner effect, by which individuals increase their chance of winning after previous victories. Her recent work has uncovered a new model to explain the etiology of depression and the rapid antidepressant actions of ketamine, involving NMDA receptor-dependent burst activity of lateral habenular neurons. Her work has led to the identification of several molecular targets for developing new antidepressant drugs. She is a recipient of the IBRO-Kemali International Prize and the L’Oreal-UNESCO for Woman in Science International award.
