Auditory brainstem potentials were recorded from scalp electrodes in 42 infants ranging in gestational age from 25 to 44 wk. The latencies of the various potential components decreased with maturation. Wave V, evoked by 65-dB sensation level clicks, changed in latency from 9.9 msec at 26 wk of gestation to 6.9 msec at 40 wk of gestation. Central conduction times in the auditory pathway also decreased with maturation from 7.2 msec at 26 wk to 5.2 msec at 40 wk. The effects of brainstem and cochlear disorders on auditory brainstem potentials were noted in several abnormal infants. The application of all of these techniques could permit an objective definition of both normal and abnormal sensory processes in newborn infants.
