Motion-sensitive circuits are crucial for visual tuning of postural reflexes

(A) Left: schematic of the fly optic system highlighting direction-selective and motion-sensitive T4/T5 cells. Right: selective expression of Kir2.1:GFP in T4/T5 cells (green).

(B) Walking path straightness of controls (light/dark blue) and experimental exemplar flies (orange) in light (top) and dark (bottom) conditions. Visual environment: 10° dots.

(C) Visual influence (left) and path straightness (right) across visual environments. Color code same as in (B). Grand mean ±SEM, Wilcoxon rank-sum test: ∗p < 0.05; ∗∗p < 0.01; ∗∗∗p < 0.005.

(D) Dynamics of the first principal component of body saccades in control (blue) and experimental flies (orange). Grand mean ±SEM.

(E) Front-leg lateral displacement (ΔFLXi+1) versus the contralateral leg displacement in the preceding step (ΔFLXi) in controls (blue) and experimental flies (orange). Grand mean ±SEM. See also Figures S6, S7, and Video S4.
