The amplitude distributions for the PP, EPSP and AP components for a unit presumed to be located in the medial nucleus of the trapezoid body.

The unit BF was 18.7 kHz and was classified as primary-like with a notch based on the shape of the post-stimulus time histogram (A). The stimulus onset was at zero milliseconds and stimulus duration was 50 ms. Note that the PP is, on average, larger than the EPSP-component.
