Learning and memory are vital for day-to-day living—from finding our way home to playing tennis to giving a cohesive speech. Some of us have personally witnessed the devastating consequences of memory disorders, whether it's the severe inability to form new memories, as seen in Alzheimer's patients, or difficulty in suppressing a recall of a memory of a highly unpleasant experience, as seen in PTSD patients. The main research interest in our laboratory is to decipher brain mechanisms subserving learning and memory.
We seek to understand what happens in the brain when a memory is formed, when a fragile short-term memory is consolidated to a solid long-term memory, and when a memory formed previously is recalled on subsequent occasions.
We also seek to understand the role of memory in decision-making, and how various external or internal factors, such as reward, punishment, attention and the subject's emotional state, affect learning and memory. In summary, we study how the central nervous system in the brain enables our mind, with a focus on learning and memory.
