Extended Data Fig. 2: Individual variation in responses to cue brightness.
From: Multimodal cue integration and learning in a neural representation of head direction
This figure provides additional detail related to the 15 flies in Fig. 3. a. Variations in HD encoding accuracy correlate with bump width, pooling data across all three cue conditions and all 15 flies (p < 0.001, Pearson’s correlation). Gray points (dim cue) are reproduced from Fig. 3c. Black and blue points show data from the other two conditions (no cue and bright cue). b. There is a trend for variations in HD encoding accuracy to be correlated with bump amplitude, but the relationship falls just short of significance (p = 0.06, Pearson’s correlation). c. Mean head direction for each individual for all three cue conditions. The length of each line represents vector strength (that is, “consistency of behavioral orientation”, or 1-circular variance). Note that consistency of behavioral orientation increases with increasing cue brightness. Different flies choose different goal directions, which is typical of navigation driven by the HD system32,33,42.
