We aim to reveal neural mechanisms of how animals adaptively control movements upon environmental and body state changes.

Research Overview

Imagine how effortlessly we reach an arm to grab a cup. Because the cup’s shape/location and our body’s condition are never identical, this seemingly simple motor task requires a sophisticated brain computation. Fine motor control is necessary even for small insects to survive in a complex environment. Recent works in the fruit fly, a genetic insect model, have made it possible to mechanistically dissect the single-cell level brain circuit map and function. By leveraging these advanced tools in flies and original behavioral paradigms, we will reveal neural mechanisms of adaptive motor control.
