Study of neural excitation in the guinea pig cochlea using low-frequency acoustic modulation.
A low-frequency tone has been shown to modulate the amplitudes of cochlear microphonic (CM) and whole nerve (N1) response to a high-frequency tone pip. Whereas the N1 responses 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.
