Interactions of adaptation and masking in the guinea pig cochlea.
Fast cochlear adaptation and masking phenomena, expressed as percent inhibition of the summed action potential, are studied from the guinea pig cochlea responses to click trains and tone bursts given previously or simultaneously to the click sequence. After preceding tone bursts, the click responses are superposed by inhibitory aftereffects dependent on the tone frequency. With interposed tone bursts, the click sequence response is masked, dependent on tone frequency.
