Extended Data Fig. 6: Learning in inverted gain.

This figure shows additional details regarding the 14 flies in Fig. 7. a. In the initial normal-gain segment, bump width is significantly negatively correlated with HD encoding accuracy (p < 0.001, Pearson’s correlation). There is a trend for bump amplitude to be positively correlated with HD encoding accuracy, but this relationship falls short of statistical significance in this group of flies (p = 0.08, Pearson’s correlation). b. There is a trend for the remapping index (in the final part of the inverted gain block) to be negatively correlated with HD encoding accuracy (in the preceding normal gain block), but this relationship falls short of statistical significance (p = 0.06). c. We finished each experiment by returning to normal gain for 200 s. This panel shows the entire experiment (including this last normal gain block) for one example fly. This is the same example fly shown in Fig. 7b. Note that the EPG bump tracks HD accurately during the final normal gain block. d. On average, HD encoding accuracy was no different in the first and last normal gain block (p = 0.67, paired 2-sided Wilcoxon test).
