Kimberly Fenn is the Principal Investigator at the Michigan State University Sleep and Learning Lab, which investigates the acquisition and consolidation of complex skills and episodic memory. A primary focus of the lab is on memory consolidation, the processing of memory after initial acquisition. This processing can serve to change memory, often strengthening and stabilizing memory, and increasing resistance to forgetting. We approach this question from several different perspectives, with a special emphasis on the role of sleep in consolidating memory. While we do not understand much about the biological and psychological functions of sleep, there is growing evidence that sleep plays a role in the process of memory consolidation. The lab uses basic behavioral paradigms as well as implementing polysomnography during sleep and using functional magnetic resonance imaging (fMRI).
