The behavior of new and old WTB seems different, but since only a few flies are tested, the results are not conclusive.
newWTB =3, PI= 0.35
old WTB from last month = 7, PI=0.04
wtb72 (old, left punishment)
wtb 74,78 (new, right punishment)

1 from sitter, 8 from wtb, 3 from rover (total N = 12)
mean(test): 0.248 SD(test): 0.7
Longterm test Control
1 from sitter, 2 from rover (N=3)
Based on 50%(20%) of statistical power, the minimum sample size is 7 (17)for both group.

After camera and punish laser adjusted, flies showed a high avoidence in the trail. Especially, when the fly was hit by punish laser in the first time of each training block. Unfortunately, there was a huge drift in the last trace after adjustment, but it shows a good avoidence in each training block.

Wild Type Drosophila were used for single fly trace testing. The basic ideal is to record the spontaneous behavior (flying trace) after punishment training by heat. The followings are 3 subjects were test with performance index (PI).
- wtb_08 (right punishment).
- wtb_10 (left punishment).
- wtb_14 (left punishment).
PS: From Julien’s paper, he demonstrates that there are 7 blocks were included in PI ( one pretest:PI1; four training test: PI2, PI3, PI5,PI6; two memory test: PI4,PI7)

This is the same experiment as I previously showed of Gr66a>Chrimson (ATR). The only difference is that the light was on for the whole experiment, so that the flies could see the light before the entered the arm. Previously the light switched on once the fly went into the arm. The phenotype is much stronger (there is some classical component in it). I was trying to reinforce left or right turns but it does not seem to work after a bit trying out. It makes sense ecologically I think, that the right or left turns are not coupled to the reinforcement systems. I also have been thinking about the CS-US relation bitter taste-turn directions does not make sense ecologically, but maybe if instead of bitter, I apply pain or heat …it could work. I was thinking of reinforcing orientation as well as a speed threshold, or any other variants. What do you think? I would appreciate some ideas. Since I want to make sure about what am I measuring: operant/place/classical…
