ABSTRACT

Auditory Brainstem Response was recorded by ipsilateral and contralateral stimulation in 20 normal hearing adults. Attempting to apply their difference for wave identification, latency of auditory brainstem response evoked by ipsilateral stimulation was compared with that evoked by contralateral stimulation. The results were as follows : 1) Latencies of wave I, II, and V were prolonged. 2) Separation of wave IV and V was more discrete. 3) III-V interwave latency was lengthened and I-III interwave latency was shortened.
