Torque Measurements 24-27.2.2026

Results from tethered flight in torque meter. Fly fixed to hook and flight torque measured while laser punishes either left or right turning. Higher PI score indicates longer stay in unpunished domain, orange colored periods are punished. Higher scores in period 9, 12 and 13 indicates learning. Fly genotype is Wild type Berlin, N=16.
Same as above, with PI adjusted to factor in initial domain preference.
A low P-score indicates that the result is statistically significant and the flies indeed learned.
Pie charts indicate efficiency of experiment success. Blue wedge represents flies that completed trial, other colors represent flies that failed. Efficiency still low, using laser at 100% duty cycle often causes flies to stop flying unless directed at exactly the right position on their antennae.

Data from the basement

I tested more wtb, this time with the switch mode protocol. Here are the results:

With the modified laser settings I was able to test 3 more wtb. Here are the results:

–> yaw torque

Before collecting the actual data I make sure that the flight simulator in the basement does its thing ;) Here are the test runs with wtb flies for different protocols:

—>> yaw torque

–>> switch mode

–>> habit formation

Bachelor Blog / #7 offspring

Below you can find the data I collected from the offspring flies:

-> offspring from trained parents

-> offspring from untrained parents

(I left out data from flies that showed negative preference during two training periods in a row)

Since the results I got after training the parental flies looked a bit odd on first sight I decided to take a closer view…

First I excluded some weird animals that either showed a larger preference for one side than avoidance or showed no avoidance two training periods in a row:

Next I compared the behavior of flies that showed avoidance but no learning with the behavior of the remaining flies:

-> Avoidance is almost the same but note the first test period!

Lastly I split the data according to male and female flies. Here is what I got:

-> Looks a bit like there is negative learning in the male flies however I don´t have enough data to be sure…

As an overview here are all the flies (except for the excluded ones) together again:
