Research Description

Research in our lab focuses on a number of related projects seeking to understand the brain circuits and cellular mechanisms that support long-term memory in mammals. The work follows an overarching hypothesis that individual significant experiences or events are organized in the nervous system as memories about items or objects and the spatial location or context where they were experienced. Fundamental to the organization of such event memories is the integration of parallel streams of information within the hippocampus or the broader hippocampal formation. One project explores the contribution of specific cortical regions to memory for objects and context, and how the consolidation of these memories is enhanced by novel experience. Another project maps neurons within regions of the memory circuit, by examining the behavioral correlates of their firing properties. Another project examines the degree to which neurons coding spatial location and directional heading, guide spatial problem solving. A final project examines SK-type potassium channel influence on behavior and behaviorally-triggered synaptic plasticity in young healthy animals and in a pharmacological model of schizophrenia-like behavior. Taken together, these projects will provide novel insights into memory organization and how neurophysiological representations of memory attributes guide memory retrieval and problem solving.
