"WebBoth low and high CF fibres of high spontaneous rate (greater than 18 spikes/s) exhibited marked rapid adaptation in their PSTH's which became most pronounced at high stimulus intensities. The ratio of onset-to-adapted firing estimated from PSTH data in these fibres increased monotonically as a function of adapted firing rate. " - Psth firing rate
