Maturation of auditory brainstem potentials in neonates and infants.
Auditory brainstem evoked potentials (ABP) were recorded in 59 healthy neonates and infants whose age ranged from 3 days to 18 months (6 age groups). Latencies of individual waves and the interpeak latencies (IPL) of I-III, III-V and I-V were analysed. A different maturational pattern was observed in the pontomedullary and the pontomesencephalic segments of the brainstem. Latencies of all waves except wave I were longer in male than in female babies. Establishment of normative data related to the technical variables employed by the individual team is a sine qua non prerequisite for adequate neurological evaluation of ABP.
