Parker Lab

Unraveling the neural circuits of visual perception and behavior through cutting-edge techniques.

Our Focus

What We Do

We aim to understand natural visual behaviors and their underlying neural circuits. We employ a variety of techniques including ethological behavioral paradigms, large-scale electrophysiology, and two-photon calcium imaging in freely moving animals.

Neural Circuits

Mapping the intricate pathways that govern visual perception.

Advanced Imaging

Using two-photon calcium imaging to observe neural activity in real-time.

Behavioral Studies

Analyzing natural behaviors in freely moving subjects to understand brain function.
