Fig 9. Blue light-induced backward waves are mediated by C4da and BO pathways and require MDN activity.

The probability of animals exhibiting backward waves upon blue light application with ablation of sensory neurons (A), or silencing AMBs or MDNs (B). Blue light was applied for 5 seconds. Genotypes are shown in S1 Table. We assessed the statistical significance by Fisher’s exact test with the Holm method. * p < 0.05, ** p < 0.01.
