The group of papers on memory reactivation and consolidation during sleep included in this volume represents cutting edge work in both animals and humans. They support that the two types of sleep serve different necessary functions. The role of slow wave sleep (SWS) is reactivation of the hippocampal-neocortical circuits activated during a waking…

The first gene-targeting studies that examined learning and memory in mice were performed in 1992 (Grant et al. 1992; Silva et al. 1992). The ultimate goal of this new field was to understand the molecular and cellular process underlying normal cognition and how they may be altered in disease states. In the years since these pioneering studies,…
