Research Description

Our lab focuses on several interconnected projects aimed at understanding the brain circuits and cellular mechanisms that support long-term memory in mammals. We work under the hypothesis that significant experiences or events are organized in the nervous system as memories of items or objects and their spatial context. A key aspect of this organization is the integration of parallel streams of information within the hippocampus and the broader hippocampal formation.

One project explores how specific cortical regions contribute to memory for objects and context, and how novel experiences enhance the consolidation of these memories. Another project maps neurons within memory circuits by examining the behavioral correlates of their firing properties. Additionally, we investigate how neurons coding for spatial location and directional heading assist in spatial problem-solving. Finally, we examine the influence of SK-type potassium channels on behavior and synaptic plasticity, both in young, healthy animals and in a pharmacological model of schizophrenia-like behavior.

Together, these projects aim to provide new insights into memory organization and how neurophysiological representations of memory attributes guide memory retrieval and problem-solving.
