Our laboratory focuses on the circuitry of the hippocampus and anatomically related regions. We use a combination of techniques, including large scale multielectrode recording, real-time signal processing and targeted optogenetic interventions and behavioral manipulations of awake, behaving animals to understand how the brain learns, remembers and decides.
