Circuit and Behavioral Physiology
Spatial learning, In vivo physiology, Circuit genetics
Understanding how the circuits of the brain interact to guide behavior is a fundamental goal of neuroscience. Our research focuses on the development and application of genetic and physiological tools in the mouse to understand how plasticity and transmission shapes memory in the hippocampal circuit and beyond.
