Brain-stem auditory evoked potentials (BAEPs): maturation of interpeak latency I-V (IPL I-V) in the first years of life.

BAEPs were recorded from 89 healthy children aged 0.1-52.1 months. The maturation kinetics of interpeak latency I-V can be well approximated by an exponential model with a horizontal asymptote. Adult values are reached by about 3 years of life. Differences between males and females become significant when maturation is completed. A non-fragmented reference range for interpeak latency I-V in the first years of life is provided.
