Research Abstract
The main goal of my lab is to elucidate the neural mechanisms by which the brain temporally organizes our memories, an ability that is particularly affected in aging and in cognitive disorders. To investigate this important issue, we use a combination of temporary brain inactivation and high-density electrophysiological recording techniques in the rat. We are particularly interested in understanding the role of the hippocampus, parahippocampal region, and prefrontal cortex, as well as their functional interactions.
