Abstract

Auditory brainstem potentials were.recorded from scalp electrodes in neonates ranging in gestational age from 33 to 43 weeks, The latencies of the various potential component decreased with maturation, Wave V, evoked by 90-100dB sensation level clicks, changed in latency from 7.18 msec at 33 weeks of gestation to 6.93 msce at 43 weeks of gestation. Central condcuction times( I-V interpeak latency) in the auditory pathway also decreased with maturation from 5.65 msec at 3,3 weeks to 5,35 msec at 43 weeks, Several kinds of patholgic condition including hyperbilirubinemia, bacterial meningitis and respiratory difficulty syndrome were also evaluated with auditory brainstem potentials, the application of all of these techniques could permit an objective definition of normal and will be helpful in abnormal infants.
