Neurophysiology of cognitive processes
My lab focuses on understanding the computations performed by neuronal circuits in the primate brain and how these computations drive higher cognitive behaviors. Specifically, we aim to uncover the neuronal mechanisms in the primate hippocampus that enable navigation through both physical and social spaces. To achieve this, we use wireless neural loggers to record neuronal activity and behavior in social animals as they freely navigate these environments. Our approach centers on studying the neural correlates of natural behaviors.
