Abstract

A permanent wire electrode was implanted in the inner ear of the green frog (Rana esculenta). Through this electrode direct current was delivered to the inner ear fluid of the frog, during recording of a spontaneous otoacoustic emission (SOAE). Both SOAE frequency and amplitude turned out to depend on DC level and polarity. Possible explanations for the observed phenomena are given, based on a dissipative limit-cycle oscillator model for SOAE generation, and the assumption that SOAE frequency depends on hair cell ion channel inductance.
