Lab information

My research lab uses rodents as a model system for investigating human memory impairment and, specifically, how different brain regions are involved in the formation and retrieval of memory. We utilize various techniques for better understanding memory functions, including stereotaxic neurosurgery, behavioral testing, and histological analysis of brain tissue.
