Population properties showing harmonic interactions in marmoset A1 (adapted from Kadia and Wang, 2003). (A) Distribution of all peak frequency ratios (CF2/CF1, CF3/CF1, and CF3/CF2) of multi-peak neurons. CF1, CF2 or CF3 are the frequency peaks of multi-peak neurons. Since a multi-peak neuron could have more than two peaks, it may be represented by more than one peak frequency ratio in this plot. A total of 56 peak frequency ratios were obtained from 38 multi-peak neurons (from Kadia and Wang, 2003). (B) Response modulations in the population of single-peak neurons in marmoset A1. Distribution of all modulatory peaks (facilitatory or inhibitory) measured from 76 of 113 neurons that showed facilitation and/or inhibition in their two-tone responses. There were a total of 139 measured peaks.
