Update on coditional FoxP manipulation. Either no manipulation at 18°c or switch to 30°c for adult flys.

Top: switch to 30°c for adult flys.
Bottom: no switch in temperatur

First data of conditional FoxP temperature switch in adult flys

Fluorescence histogram

Proof of concept. I was playing around with ImageJ and found that there is a built in function already that does analyze the fluorescence intensity. I am just not sure exactly what it tells us. This is only as far as I have gotten yet.
The image below is the one I used.

Dwelling Time

on Monday, January 27th, 2020 1:45 | by

The code generates the dwelling time for each period as well as the median dwelling time for each period. The code has also been implemented on grouped data but it only generates graphs for one of the groups, not both. Currently investigating why

Just gloating here

Valence and dopamingergic neurons

on Monday, January 27th, 2020 1:05 | by

I have been sorting and feeding flies ATR (in total about 7400 flies divided between 170 vials). Emer has been conducting the experiments during the previous week continuing this week.
Including the flies from today we have a total of 172 experiments divided between 7 experimental groups. Including the data from the Turkish students it is well over 230.

I looked at the control experiments and they look as expected. Perhaps even better than what the Turkish students had.

Optomotor response

Slowly are we getting closer to getting a optomotor response
I made the following changes

  • Glued flies to a needle rather than the plastic optic fiber
  • Head of fly was not glued, the fly was able to rotate its head
  • I put focus on making sure to get the fly as straight as possible
  • Contrast between black and white was increased
  • The light was adjusted to increase the brightness within the arena
There is an optomotor response but it is entirely generated from just one single fly, the remaining 4 flies had no OR.

  • Other projects I have been working on this week
  • Working out the new FPGA software for Flight simulator
  • Collecting flies for Optogenetics Experiment
  • Implementing dwelling times in DTS R script
  • Implementing Metadata comparison in R script
  • Grant writing

Updates on Optomotorics and DTS evaluation

on Monday, December 16th, 2019 1:57 | by

DTS: The graph below is an example image of how color according to category looks like. The output now adds a unique color for each category. The one below has three different colors as the pretest phase does not use any pattern and is therefor read as its own category.

Optomotorics: The software worked as it should although it had a couple of issues. Wrong information in xml sheet was one of them: this is now fixed so that it enters duration as seconds and the correct terms for a_pos and j_pos are used

The other issue was that at the end of the experiment about 40-50 data points were missing/removed. My speculation was that this either had to do with data being removed at the end of the experiment or that it ended prematurely. Turns out that the later was the cause.

As simple as it might seem, there was a lot of investigation to find this bug. To fix this I simply had to replace
if curr_count >= self.test_time() - 100:
with
if curr_count >= self.test_time() - 30:
