The brainstem response to brief tones contains a large vertex-positive component. If high-pass filter settings above 20 Hz are used, particularly with high rolloff slopes, the morphology of the response changes so that a vertex-negative wave becomes the most prominent component of the response. The amplitude of the response is unaffected by stimulus presentation rates of up to 35/sec. Tones with longer rise times have greater frequency specificity, but at rise times of greater than 5 msec, the… CONTINUE READING
