There are three primary aims of research conducted in Dr. Colombo's laboratory. The first is to elucidate the neuronal mechanisms of memory formation with emphasis on the roles of signaling proteins, including kinases, phosphatases, and transcription factors. The second aim is test hypotheses regarding independence or interactions among multiple memory systems. The third aim is to apply results of studies of the neuronal mechanisms of memory formation to studies of age-related memory impairment under normal (e.g. non-pathological) aging conditions. Research on these three aims is conducted in parallel and combines behavioral analyses of learning and memory in rats with molecular-biological techniques to study the mechanisms of memory formation at both the cellular and the brain systems levels of analysis.
