Results for Dop1R1-RNAi, Amon-RNAi and the course data
on Tuesday, May 21st, 2024 8:11 | by Maja Achatz
Firstly, I did an experiment where Dop1R1 was knocked down via RNAi. The following shows the results:

For the next experiment, the controls groups were the same, however in the experimental group Amon was down regulated. These are the results:

Lastly, in the course the data for the larvae experiment was collected only under blue light, so I used the same crossings and tested them under red light to use as a control.

Results for amon-RNAi and MB143B
on Monday, February 26th, 2024 12:17 | by Maja Achatz
The first figure shows the results for the preference test (salt/pure) conducted with amon-RNAi only under red light.

For the next experiment I conducted the same preference test but with the split-gal4 line MB143B under red and blue light.

Results for MB+DANs and MB054B
on Monday, September 25th, 2023 11:07 | by Maja Achatz
The first experiment tested the activation of KCs with simultaneous ablation of pPAM which showed the following results:

Green: UAS-ChR2-XXL; LexAop-rpr x 58E02-LexA; H24-Gal4
Lightgrey: UAS-ChR2-XXL; LexAop-rpr x H24-Gal4
Darkgrey: UAS-ChR2-XXL x 58E02-LexA; H24-Gal4
The next experiment was conducted with the split-Gal4 line MB054B (DAN-f1/DAN-g1) and showed the following:

Optogenetic stimulation of DANs
on Saturday, September 2nd, 2023 11:09 | by Maja Achatz
With the focus on dopaminergic neurons, I conducted two experiments with two different driver lines to see how the naive gustatory behavior in Drosophila larvae is affected.
The first cross I tested was R58E02-Gal4 x UAS-ChR2-XXL, which gave me the following results:


As seen in the figures, there was no effect under blue light.
For the second experiment I crossed TH-Gal4 x UAS-ChR2-XXL with these results:


With this experiment, there was an effect on gustatory behavior as there is a clear significant difference between the experimental group and the control group.

Preferences with higher salt concentration
on Monday, August 7th, 2023 12:46 | by Maja Achatz
The following plots show the results after I increased the salt concentration from 1,5M to 2,5M. It shows that the difference between the control groups and experimental group are not significant anymore.
