Inhibitory neurons have more homogeneous and stronger binaural inhibition. a, Diotic, contralateral, and ipsilateral tuning curve for one example neuron. The maximum activity at each tuning curve was used to measure three metrics: diotic to contralateral gain, diotic to ipsilateral gain, and aural dominance index (ADI). b, Three metrics in one example field of view (FOV) for the excitatory (top, 291 × 291 µm) and inhibitory (bottom, 291 × 291 µm) neurons. The direction of FOVs is the same as in Figure 1d. c, Proportion of FOV that have clusters at different pairwise distances for those three metrics (top, middle, and bottom). The dashed lines indicate median values for the excitatory (orange line) and inhibitory (green line) neurons. d, Top, Diotic to contralateral gain. The median is 1.07 for excitatory (orange line) and 0.89 for inhibitory neurons (green line). The effect size is 0.048, and the 95% confidence interval is 0.023 and 0.073. Middle, Diotic to ipsilateral gain. The median is 2.81 for excitatory and 1.96 for inhibitory neurons. The effect size is 0.091, and the 95% confidence interval is 0.046 and 0.136. Bottom, ADI. The median is 0.40 for excitatory and 0.39 for inhibitory neurons. The effect size is 0.018, and the 95% confidence interval is −0.036 and 0.072.
