The main objective of research in my laboratory is to understand the neural circuit-mechanisms underlying neuropsychiatric diseases including drug addiction, feeding disorder, depressive disorder, social impairment and movement disorder. Given the circuit and synaptic complexity of the brain, the characterization of specific neural circuitry responsible for behavioral changes has been challenging. To address the anatomical and functional properties of neural circuitry involved in these mental disorders, our laboratory applies and develops a variety of molecular strategies together with electrophysiological approaches.
