This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. The last ten years have produced a wealth of new evidence for an important role of sleep in learning and memory consolidation. Building on these new findings, we have obtained preliminary evidence that sleep contributes to specific aspects of learning and memory consolidation and that specific stages of sleep contribute to specific component processes. We now propose to address three fundamental unresolved issues concerning sleep and memory consolidation: 1) what kinds of memory does sleep help to consolidate, 2) which components of the consolidation process does sleep contribute to, and 3) which stages of sleep are involved in these processes.
