Study of Neural Excitation in The Guinea Pig Cochlea Using Low-Frequency Acoustic Modulation

Abstract

A low-frequency tone has been shown to modulate the amplitudes of cochlear microphonic (CM) and whole nerve (N₁) responses to a high-frequency tone pip. Whereas the N₁ response was always reduced and had two maxima per cycle of the low-frequency signal, the CM response changed from a single- to a double-maxima pattern as the modulator intensity was increased.
