Results for MB+DANs and MB054B

on Monday, September 25th, 2023 11:07

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

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

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.

The following shows the preference and avoidance towards Sugar and Salt for the Canton S larvae. In addition, the larvae were tested unter blue/room light, to see if there were any differences.

Preference Results for Canton S larvae, Pure vs Sugar and Pure vs Salt

on Monday, June 12th, 2023 1:49

The following figures show the results of the preference tests with Canton S. I tested Pure vs Sugar and Pure vs Salt under two different circumstances. I tested the larvae in normal light and also under blue light.
