title: Study of a simultaneous lobe-vertex and membrane-vertex recording technique in auditory brainstem response.
abstract: The study of a simultaneous lobe-vertex and membrane-vertex recording in auditory brainstem response was performed in normal adults and in patients suffering from brainstem disorders. It was demonstrated that in normal subjects the detectability of waves I and V depends on the site of the recording electrodes and there is no statistical difference between the two recording methods in the latencies of the two waves. We reported 3 typical cases that illustrate the value of this recording method in the detection of the cochlear nerve or the brainstem disorders.
