[Cochlear responses to dynamic click pattern in the guinea pig].

Fast cochlear adaptation expressed as the percent of inhibition of the summed action potential, has been studied from the guinea pig cochlear responses to click trains, ramps, and steps in both directions. The transition time function of adaptation to constant click trains does not depend on the click strength, but rather on the click interval. At the background of steady state adaptation, click steps produce only transient changes of the adaptive state, opposite to step direction.
