Our lab studies how the brain learns to control the timing of actions. Using reaction-time tasks and related behavioral paradigms, including self-timed tasks, we investigate the neural basis of stimulus-response learning, rapid action initiation, forelimb and whole-body motor control, and interval timing.

We combine behavioral analysis, circuit manipulation, and neural recording. Our current focus is on chronic Neuropixels recordings in the basal ganglia and frontal cortex of rats as they learn, beginning with their first exposure to a behavioral training box or maze and continuing over weeks to months. During this time, animals may encounter changes in task structure or learn multiple tasks in different settings. By tracking the same neurons throughout learning, we can address previously intractable questions about how neural circuits change as new behaviors are acquired.
