Sensory manipulations affect the percentage of time spent stopped on cones. Color-coded (see Fig. 1F) box plots indicate the percentage of time stopped on each surface of the arena, with white indicating the arena floor. (A) Intact flies in the light (N=25). (B) Intact flies in complete darkness (N=25). (C) Flies with antennae immobilized in the light (N=40). (D) Flies with antennae immobilized in complete darkness (N=40). Statistically significant differences within and across trials were determined using the Mann–Whitney U-test (P<0.05, with Bonferroni correction); crosses denote outliers. See Fig. 4 for explanation of letter codes for homogenous groups.
