Abstract Both nocturnal and diurnal sleep enhances memory consolidation. Rapid eye movement (REM) sleep enhances procedural memory traces, whereas non-REM (NREM) sleep, particularly slow wave sleep (SWS), enhances declarative memory aspects. It is speculated whether an increase in time spent in the NREM stage would provide additional memory benefits. The goal of this research design is to establish whether declarative memory is dose-dependent on the length of the NREM episode achieved during sleep. First, a visuospatial object recognition task and a procedural finger sequence tapping task will be used to establish that NREM-only sleep is capable of improving declarative memory without the assistance of REM integration. Next, diurnal sleep episodes of several different time intervals will be used to quantify potential enhancements in memory retrieval based on amount of NREM sleep achieved. It is predicted that memory profits will increase in a dose response manner, implying that increased length and incidence of NREM sleep will provide significant, linear memory improvements in humans.
