Figure 7.

Selected filters show genetic separation of yaw and sideslip optic flow processing. A–D, Although the lines c730-gal4/UAS-TnT (A) and 201y-gal4/UAS-TnT (B) were wild type, expression of DT with c739-gal4 (C) and 201y-gal4 (D) resulted in highly disrupted yaw filters without much affecting the sideslip filters. E, F, Crossing these lines with a fly homozygous for MBGal80 partially rescued the yaw optomotor filters in both lines, which might indicate that the output of the MBs impinges on the yaw optomotor circuit downstream of the optic ganglia. *p < 0.05, **p < 0.01, ***p < 0.001. An asterisk over the filters indicates a significant difference in peak height. The numbers listed after the name of the line indicates the N in the no odor and odor conditions, respectively.
