Here, I present you the results of using Blue light for photopreference and adding a pulsed Red light. These experiments are controls required for using Optogenetics to study Photopreference. I used the Blue light at different intensities, and calculated the Choice Index (CI) and the proportion of flies in each tube of the T-Maze (White: Bright, Black: Dark, Grey: Elevator).
I recently combined the two TbH-lexA lines (54954 & 54075) with CD8GFP, and the TDC2-GAL4 line with CD8RFP, in order to compare their expression patterns. Here I present some of the dissections. The confocal is not working properly, but it is relatively good to draw some conclusions.
TDC2>GFP and anti-TβH (Scholz’s Lab)
TDC2>GFP (Gerber’s Lab)
anti-TDC2 (Goodwin’s Lab)
After refining my DA screening, I end up having three interesting GAL4s which lead to changes in photopreference after expressing Shibire and rising the temperature. What I am trying to do now is to understand if they label the same neuronal population or not.
