Neighboring excitatory neurons have similar ILD preferences. a, Weighted ILD in one example field of view (FOV) for the excitatory (left, 256 × 256 µm) and inhibitory (right, 160 × 160 µm) neurons. The direction of FOVs is the same as in Figure 1d. b, Pairwise tuning correlation (y-axis) versus distance (x-axis) in the same example FOV for excitatory (left) and inhibitory (right) neurons. The lines indicate the best linear fit to the data. c, Top panels, Best linear fitted lines of tuning correlation versus distance in all FOVs for the excitatory (left) and inhibitory (right) neurons. The gray lines indicate the pairwise tuning correlation and distance are not correlated (p < 0.05). Bottom panels, Best linear fitted lines of best ILD difference versus distance in all FOVs. d, Similar to c but for tone frequency instead of ILD. e, Proportion of FOV that have clusters at different pairwise distances in all FOVs for the excitatory (left) and inhibitory (right) neurons. For example, when the paired neuron distance is ≤125 µm, clustered and random ILD tunings of excitatory neurons were found in 11 and 7 FOVs, respectively (proportion, 61%). In contrast, ILD tunings of inhibitory neurons were randomly distributed in all nine FOVs (proportion, 0%). Notice that FOV that had <10 significantly tuned neurons were excluded (see Materials and Methods). f, Similar to e but for tone frequency instead of ILD.
