Wave VII recognizability in brainstem auditory-evoked potentials.
Brainstem auditory-evoked potentials (BAEP) recorded with a far-field from the scalp technique are generally described as 7 positive waves in the initial post-stimulatory 10 ms period. Also at high stimulus intensities, the Jewett wave VII appears to be undetectable in the majority of normal subjects. We present an original recording method to reproducibly detect this late BAEP wave. 48 normal ears were examined and wave VII was detectable in all the recordings with clicks delivered at an intensity of 75 dBHL.
