The infant arousal response involves subcortical and cortical responses occurring as a sequence of stereotyped behaviour regardless of the eliciting stimulus. The spontaneous activity of these responses during sleep, however, is uncertain. We examined the spontaneous arousal pattern in normal infants to determine the sequence of responses, and to examine(More)
Infants are prone to accidental asphyxiation. Therefore, we studied airway-defensive behaviors and their relationship to spontaneous arousal behavior in 41 healthy sleeping infants (2-26 wk old), using two protocols: 1) infant was rebreathing expired air, face covered by bedding material; and 2) infant was exposed to hypercarbia, face uncovered. Multiple(More)
Polygraphic studies of stimulus-induced arousals from sleep in young infants have identified a highly consistent sequence of reflex responses occurring during the 2-4 second period prior to full behavioral arousal. The initial responses in this sequence are an augmented breath (sigh) coupled with a sleep startle that is then followed by stereotyped(More)
