title: Effect of stimulus intensity variation on brain-stem auditory evoked potentials: comparison between neonates and adults.
abstract: Brain auditory evoked potentials (BAEPs) were recorded from 40 adult subjects and 40 neonates at 80 and 60 dB (nHL) to compare the effects of stimulus intensity variation on waves I, III and V and on intervals I-III, III-V and I-V. The results show that the changes in latency for wave, I, I-III and I-V intervals are significantly greater in neonates than in adults. So the effects of stimulus intensity variation on BAEPs are different in neonates and in adults and a major effect is in the peripheral auditory mechanism.
