How & Why we behave?

We are design to behave all the time.  The goal of our laboratory is to unravel the brain mechanism that coordinates optimal behaviors. Recently, we are focusing on the thalamus that integrates sensory and motor information and relays it to the cortex. In many neurological conditions, from depression to Parkinson’s disease, this thalamic function is abnormally activated or inhibited to induce severe behavioral symptoms. By using pysiological and genetic technologies, we have revealed principles on the thalamus-dependent behavioral control with hoping that our study opens up promising new avenues for alleviating patients the suffering of patients.

How the brain encourage us to explore the world every day? Since 2014, we have continued another research project on the motivation of exploration, supported by The Samsung Science & Technology Foundation. Inspired by that animals show explorative behaviors when they see small objects, we are trying to identify the target neurons involving object exploration and acquisition in mice.
