I want to know which octopaminergic neurons are involved in the phototactic switch after wing clipping. So I started with a screen for some subgroubs of tbh-GAL 4. After testing the flies in RT with a T-Maze, I tested the same flies again in 32 degree. I expect, that wingless flies go to the light, so the Choice Index should increase. The Figure 1 shows the results of only 2 experiments (39942-tbh-GAL4 only one experiment).
