Figure 6. Circuits that compute responses to dark edge motion receive inputs from L1, L2 and L3.

Figure 6

(A–R) Turning behavior in response to various rotational stimuli. Each panel shows the experimental Gal4(1)+Gal4(2)>shits condition (blue) as well as the corresponding Gal4(1)+Gal4(2)/+ (red) and UAS-shits/+ (green) controls. Shading denotes +/− 1 SEM. Genotypes and schematics are shown to the left. Number of flies run per genotype is indicated in parentheses. The bar plots next to each time trace show integrated responses over a 250 ms window beginning 80 ms after stimulus onset. *p<0.05, ***p<0.001, tested using two-tailed t-tests against both controls. Error bars denote +/− 1 SEM.

(A,D,G,J,M,P) Turning responses to rotating light edges. Multiple light bars appear on a dark background. One edge of each bar then expands in the same direction at 80°/s. (B,E,H,K,N,Q) Turning responses to rotating dark edges. Multiple dark bars appear on a light background. One edge of each bar then expands in the same direction at 80°/s. (C,F,I,L,O,R) Turning responses to rotating square wave gratings with 40° spatial period and moving at a contrast frequency of 9 Hz. See also Figure S6.
