About the Lab

Our lab investigates the neural mechanisms underlying learning and memory, with a focus on synaptic and structural plasticity. We study long-term potentiation (LTP) in vivo and explore how LTP is affected by drugs, neurodegenerative disorders, and other experiential factors. Using both rodent and human models, we also investigate spatial navigation and behavioral flexibility (in the spatial domain) in relation to the behavioral and cognitive functions of the hippocampus and frontal cortex.
