Division of Behavioral Neuropharmacology
Behavioral pharmacology is a field of science that analyzes higher-order functions of the brain by observing behavioral changes in individuals. Based on this experimental approach, we are analyzing the mechanism of emotions (pleasant or unpleasant) and cognition (learning and memory) at multiple levels, from molecules to cells, circuits, and individuals. We also investigate the pathophysiological mechanism of psychiatric disorders, including schizophrenia, drug addiction, and bipolar disorder. As a member of ICBS, we widely collaborate with basic and clinical researchers inside and outside the university to produce high-impact research results that can be disseminated worldwide.
Taku Nagai, Professor
My research field is behavioral neuropharmacology and neurochemistry. I am investigating the mechanisms of emotional/cognitive function and trying to develop new treatments/drugs for mental illness.
Shinichiro Taya, Associate Professor
Previously, I have been involved in the analysis of the pathogenesis of schizophrenia at Nagoya Univ. and epilepsy at NCNP. I try to elucidate the pathogenesis of psychiatric and neurological disorders using biochemical analyses.
Hiromi Sano, Associate Professor
I’m investigating the mechanisms that how emotion and motor control are regulated in the neuronal circuit. I also have interests in pathophysiology of emotional and movement disorders, and in developing novel therapeutic strategies.
Xinjian Zhang, Assistant Professor
Originally from Jiangsu Province, China, it has been more than 10 years since I came to Japan. During this time, I was engaged in the analysis of phosphorylation signals in negative emotions at Nagoya University (Prof. Kaibuchi’s Laboratory). Currently, I am studying the molecular mechanism of reward learning.
Hisayoshi Kubota, Assistant Professor
I was studying the influences of lifestyle habit on the emotional/cognitive function. Currently, I am trying to identify the neural circuits involved in behavioral addictions and to elucidate the pathological mechanisms of psychiatric disorders focusing on risk genes.
