Local changes in computational non-rapid eye movement sleep depth in infants

Newborns and young infants spend most of their time sleeping, and the quality of sleep has been found to be important for their development. Although the contribution of each sleep stage is different, both REM and NREM sleep have important functional roles in brain maturation and in normal synaptic development (Graven, 2006). As for NREM, deep NREM is considered to be the most important sleep stage for infants. In adults, slow wave sleep and slow wave activity (SWA) of NREM sleep are homeostatically regulated and considered a measure of sleep pressure (Borbély and Achermann, 1999).
