Document Summary

Sleep in preemies; monitoring kicking/heart rate in fetus while in the womb; direct monitoring through eeg one example is the exteriorized sheep fetus. 6-7 month old fetus develops rem/nrem sleep precursors. By the end of the 8th fetal month, have established sleep patterns that mimic post-natal quiescence and activity. In newborns: quiet sleep represents precursors to stages 1,2,3, and 4; active sleep is developmental precursor to rem. Absent in newborns (no intrinsic period) and consolidation of infant s-w cycle (~5 months postnatal: wake up time. Infants (less than 2 years): early (6-8 am), regardless of bedtime. Elderly: reduced sws and (often) rem, more stage 2. Rem) as possibly crucial for wiring brain circuits in species born immature.
