In this subset of the data, we find a robust recapitulation of our original results: there is a highly significant peak in the latency distribution of predictive relationships between spike counts and song with the expected RPE timing latency (0–150 ms) (p value < 0.01) and a highly significant number of predictive relationships (p value < 0.01), repeating results in Figure 3 .
