Optogenetics and photopreference

on Monday, July 24th, 2017 10:39 | by

I am still trying to set up the optogenetics tools for my photopreference assay. These are the results so far. I combined the result obtained with Chrimson in the second chromosome and in the X chromosome, because they were identical.

Blue: only blue light.

Red: Blue light + pulsed red light.

 

 

I think Chrimson is already activated under my blue light condition.

Optogenetics in Photopreference (Pretests)

On this opportunity, I changed the size of the tubes in order to see if that has a impact on the proportion of flies that ended in the elevator.

Optogenetics in Photopreference

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).

Starting with optogenetics in photopreference

on Monday, June 19th, 2017 2:58 | by

I am thinking of using optogenetics to study the neural substrates of photopreference. Here I present some controls that I have to do before starting. This is a T-Maze with blue light instead of with light.

Problems solved? (photopreference)

These are the last controls I needed in order to be sure everything wrong was gone. They are not the best, but I think they show some clear results.

Yellow: Room Temperature

Green: 32°C

Some controls for the photopreference Troubleshooting

To find the source of the problems I have seen in the T-Maze, I use lines from our stock and tested them in the T-Maze. This were reared at 25°C.
