Optogenetics in Photopreference (Pretests)

on Monday, July 10th, 2017 12:31 | by

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

on Monday, July 3rd, 2017 1:26 | by

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 | 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

Measuring locomotion in the Joystick? Something seems to happen…

Example of ON/OFF traces.  And then the wiggling was measured in both conditions (with and without light). It seems like they move more when they are in the light side. I also did measure the derivative with a tau=2 (in case the sampling is over the temporal frequency of fly behavior)
