Cochlear microphonics (CM), action potentials (AP) and endochochlear potential (EP) were recorded on guinea pigs. The introduction of a small quantity of KCl solution (0.1 N) in the perilymph provoked a moderate decrease of CM and AP. During the period of depressed but stable amplitude, the presentation of intense sounds provoked an exaggerated susceptibility to fatigue and a delayed recovery. Similar changes were observed in the evolution of EP. However, the recovery was slower for EP than for CM. The results, as a whole, suggest that the fatigue which is manifested in the depression of cochlear potentials is related to a leakage of potassium ions from endolymph to fluids spaces within the organ of Corti.
