Auditory brain stem responses recorded and processed by analyser HEAD/TNS: normative data

In 31 healthy people (14 men, 17 women) the authors analysed the shape of auditory brain stem responses (ABR) registered on short acoustic stimulus (click) in the vertex. Beside the shape of the responses was also evaluated the dependence of the latencies of each peak of ABR on the position of the reference electrode, on the character of the stimulus and on sex. The data obtained made possible producing one's own laboratory norm for measuring the normality of ABR recorded on the registration apparatus, with TNS microcomputer as its central component.
