Positive Control: Gr28bd-G4, TrpA1-G4

This week we worked on perfecting the fly hooking. Some of the data we got is as follows (Data from just one fly).

The mean ratio of the flies that stay in the middle during the experiments.

Correlation plot between the mean ratio of the flies that stay in the middle versus the Weighted PIs

Slope = 0.0053
Intercept = 0.240
R square value = -0.03834

contrary to the expectations, there seems to be no correlation .

Lena Matzeder just finished her Bachelor thesis, entitled “Is anxiety a factor influencing photo-preference in Drosophila melanogaster?“. She administered Diazepam (valium) to flies and asked them if that changed their preference for bright or dark places. A warm welcome to Weitian Sun, a Master’s student who will be testing candidate genes for their involvement in operant self-learning.

I have now cleaned the site from all malicious code and installed a few new plug-ins which I still need to properly adjust all settings. The site should now almost be back to normal, please resume posting your data and let me know if there is anything that still needs fixing!

I have just realized that there is no “new comment” section, so we have access only to the last 3 comments. Since there is also no way to have them as rss feeds (only public posts are feeded), it makes it possible to loose track of comments, if somebody (like I just did) look and comment the posts only once in a while.

Is there a way to manage this?

My camera is bigger than Julien’s :mrgreen: I realized that the camera I had been using to track the laser position in my flight simulator didn’t quite fit with the way everything is arranged now. I remembered I had seen an old camera in the basement, so I went there to check it out. It worked really well and it provides a fantastic picture of the fly. It’s just that it is now the largest piece of the equipment:

The workshop has been busy recently…
