Popis:	Spike discharges of medullary units ofRana ridibunda in response to tones of optimal frequency for the neuron, with sinusoidal amplitude modulation, was studied. Reproduction of sound modulation in unit activity was assessed by the use of phase histograms of responses corresponding to the period of modulation. Amplitude modulation was reproduced in the firing pattern of neurons of the dorsal nucleus over a wide range of modulation frequencies and carrier levels. Accentuation of small changes of amplitude for modulation frequencies of 70–150 Hz was observed in many neurons of the superior olives. The phase of the response was a linear function of modulation frequency both in the dorsal nucleus and in the superior olives. The greatest enhancement of amplitude changes corresponded to low modulation indices.
