Research

Neural circuits are the neural basis for emotions. Anxiety disorder has been recently defined as disruption in neural circuits. Our previous study has demonstrated that optogentic control of astrocytes could help to repair the damaged neural circuits in neuronal degeneration diseases. Currently, we coordinate optogenetic tools with pharmacogenetic tools to manipulate neurons and glia cells to study the neural circuits that control anxiety-like behaviors under physiological and pathological conditions. Cre-transgenic mice, neural circuit tracing techniques and in vivo optical imaging are also employed to study the neural substrates in control of innate and pathological anxiety.
