I experienced some issues with the first batch of the UAS-TNT control flies, theyh ad a very low learning curve. The second batched looked fine but the still have a slightly lower learning PI during Test1 than I want.

1. ato-Gal4 x conditional KO —> Removing FoxP in Dorsal Cluster Neurons for Buridan
2. cmpy-Gal4 x conditional KO —> Removing FoxP in Protocerebral Bridge for Buridan
3. temperature switch at embryo stage but shorter time —> for replicating the KO phenotype
4. LexA + Gal4 together to analyze larval brain (I have always considered larvae except for this experiment, so I am doing it to be more complete)

Furthermore, for not loosing time this week I did:

1. Leipzig presentation
2. Wrote a bit of results for paper/thesis

1. Protocerebral bridge lines X CD8-GFP
2. C380-Gal4 X UAS-gFOXP;UAS-Cas9 (+ 2 controls)
3. stinger;Foxp-iB X FoxP-KO

Last week (1.-7.Apr 2019) we noted how many flies want to fly more than 8 min and here is the result (only the ones we noted):
– Wild type: 8/9 (88%)
– ElavGal4 x UAS-Ryr 28919: 3/12 (25%)
– ElavGal4 x UAS-Ryr 65885: 6/35 (17%)

Wild type:

ElavGal4 x UAS-Ryr 28919:

ElavGal4 x UAS-Ryr 65885:

New Findings:

Elav-Gal4 x UAS-SERCA 44581 flies => Lethal before adulthood! (in all 5 vials so far)

A flight performance test to see how the flies are behaving while flying. They have a slightly lower flight duration compared to the genetic controls but nothing that should impair them in the experiment.

The learning experiments are ongoing. I am doing n=15 for each line and each experiment, both Composite Control and also a Isolated Operant experiment. The Composite control experiment is done but I only got 13 flies for Isolated Operant. I do not want to preanalyze the data and will therefor post it when all the flies are done.
