Coherence between variations in instantaneous firing rates of ON1 and ANs. A, Instantaneous firing rate of ON1 and AN2 (for excerpts shown in Fig. 2 B) during monaural and binaural stimulation (left). The difference in instantaneous firing rate between response to binaural and monaural stimulation is shown on the right. B, Coherence of firing rate differences (as shown in A, right) between ON1 and AN1 (top) and ON1 and AN2 (bottom). ON1-ipsilateral stimuli had CF of either 4.5 kHz (black lines) or 30 kHz (gray lines); AN1- and AN2-ipsilateral stimuli were 4.5 and 30 kHz, respectively. Curves are means ± SE; n = 9.
