New link between sleep arousals and body temperature may also be connected to SIDS

What is the origin of these arousals? Scientists have discovered that brief arousals are probably triggered by the intrinsic electrical noise from wake-promoting neurons (WPN) in the brain. Their research reveals a previously unrecognized neurophysiological mechanism that links sleep arousals with temperature regulation, and may also provide an important new link between temperature and Sudden Infant Death Syndrome (SIDS).
