Recent wtb test

There often seems to be a strong preference for a side. The laser was off.

Fly had a strong pref for left side, laser was off

Flies often seem to have a strong preferenc for a side. In the imiage below the top fly was punished for left torque and survived, the fly below was punished for the right torque side and died.

Trails with drift

Testing of the repaired torque-meter

I’ve started again to test the set-up after repairs. It does not seem to be perfectly stable ,with some drift in the positive direction. Most often, it seems that the amount of drifting would be fine for measuring.

Therefor I tried measuring some flies. A problem now is a very negative baseline, when the fly stops flying. Also the response for left and right seems not to be equal.

So now I’m trying to get the line close to 0, so that I have conclusive results if the set-up if usable at the current state.

2 examples of drift:

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

A highly hypothetical scenario of how the distribution of dwelling times could be. Even if unrealistic, it still illustrates the problem of using median instead of mean.
