Optomotor response

General behavior of the MBON-2


I wanted to expand and look into some general behavior of the mbon-2 flies. Mostly as a complement to the already existing data.

Progress Week 29

on Monday, July 20th, 2020 1:38

-Introduced Sayani to the wonderful world of Drosophila

-Been doing some DTS coding

-Preparing flies to do optomotor response for Mathias Raß

Progress week 26-28

on Monday, July 13th, 2020 1:39

Updates in DTS code

Refreshing dissection skills

Tdc2-Gal4 expression in adult brain
Actin-GFP expression in adult brain

Progress for week 25:

on Monday, June 22nd, 2020 1:58

DTS coding
-Added progressbar for data validation
-Updated the progress bar (see figure 1)
-Fixed bug with wrong sample size (see figure 2)
-Fixed bug with unorganized barplots (see figure 2)

Figure 1. Updated progress bar
Figure 2. Correct sample size and restructured barplot

Exp always to the right:
plotOMparams <- plotOMparams[order(plotOMparams$desc),]
plotOMparams$group <- factor(plotOMparams$group, levels=paste(unique(plotOMparams$group)))

Samplesize fix:
samplesizes.annotate(boxes, as.numeric(table(plotOMparams$desc)))

progress <- c(round(l(100/(length(xml_list)))),round(flycount(100/(totalflies))))

-Finished rescreening last Thursday. Started to evaluate the new data

Optomotor platform: Ran a few more tests to confirm that the machine was still working, it is. I also adjusted the 0 line so that it is at 0, by readjusting the “zero line” screw. Looks much better now but it is still not perfectly at 0. A difference 0.1 on the computer screen translates to 100 in the evaluation chart.

Pooling data not possible: working on a fix

Statistical evaluation of OR


Recently I measured the optomotor response in T4/T5 flies. As expected, they did not respond to the optomotor stimulus as seen in the left chart below. However, statistical evaluation struggles to quantify this difference. It might be that this is because of the low sample size, or that we are using the wrong statistical analysis?

Some issues with UAS-TNT control

on Monday, April 20th, 2020 1:57

I experienced some issues with the first batch of the UAS-TNT control flies, theyh ad a very low learning curve. The second batched looked fine but the still have a slightly lower learning PI during Test1 than I want.
