The Walsh Laboratory

Investigating the neural circuit mechanisms underlying motivated behavior
Research Synopsis

Welcome to the Walsh Lab!

We combine state-of-the art whole brain optical clearing methods, light sheet microscopy, in vivo imaging, and machine learning based behavioral analysis to elucidate the neural adaptations responsible for motivated behavior.
