Although all of the infants were within the normal range on the mental development test, we found a negative relationship between the number of times per hour that the snore-related arousals occurred, and the infant's score on the mental development index.
Hibernators must have compelling adaptive reasons for interrupting torpor with bouts of arousal, says Martin, because warming a chilly body bums considerable energy.
It also causes a brief arousal ("microarousal") that terminates the apnea.
