Extended Data Fig. 4: Comparing one-cue environments and a two-cue environment.
From: Multimodal cue integration and learning in a neural representation of head direction

This figure shows additional detail for the 18 flies in Fig. 5. a–c. There is no difference between the visual cue and the wind in terms of HD encoding accuracy (p = 0.28; a), bump width (p = 0.27; b), or bump amplitude (p = 0.20, paired 2-sided Wilcoxon tests; c). These plots show data from the two initial single-cue environments, prior to the onset of the two-cue environment. Thick horizontal lines are mean values. d. The offset during the two-cue block is equally similar to the initial offset with respect to the visual cue and the initial offset with respect to the wind (p = 0.52, paired Wilcoxon test). e. Offset data for both initial single-cue environments and the two-cue environment, for all 18 flies. The angle of each line indicates the mean offset during that block; the length of each line indicates the vector strength of the offset (that is, HD encoding accuracy). Note that there is no relationship between the initial visual offset and the initial wind offset. Note also that there is no tendency for the visual cue or the wind to dominate the offset in the two-cue period. f. Same but now color-coded by cue order. Note that the offset in the two-cue environment is generally similar to the offset in the environment with cue 2. The exceptions to this rule are generally flies where the offset was not stable (for example, the fourth fly in the top row, or the fifth fly in the bottom row).
