Abstract

behavioral states glabellar reflex perinatal factors reflex augmentation sensorineural processing
In newborn infants, the eyeblink response to a tap to the glabella occurs with increased amplitude if the tap is accompanied by a tone which is itself too weak to elicit an eyeblink response. In this study, we examined the effects of several subject variables on this response and its augmentation. These were weight of the infant at birth and at time of testing, the infant's gestational age and postconception age at testing, gender, 1-min and 5-min Apgar scores, health status, type of anesthesia administered to the mother during delivery, number of hours since birth, and behavioral state. Of these, behavioral state was shown to affect the baseline response to the glabellar tap alone and, to a smaller degree, the percent of reflex augmentation in full-term infants. In addition, preterm infants' responses to the tap alone were smaller than those of full-term infants, indicating a developmental increase in reflex reactivity. There was, however, no difference between these two groups in terms of percent of reflex augmentation.
