Mean or median?

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.

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

Comparison between the old and the new Wtb data.

Summary of the self-learning experiments with Wtb. The laser was adjusted for the later trails. This is resulting now in a better avoidanc in training (orange bars).

The different MBON types and their averaged preference index for Test2/3 during isolated operant component in the flight simulator. Each letter corresponds to a randomized MBON subtype. All but one is being displayed due to low sample size.

Learning paradigm with Wild Type Berlin flies

Been conducting a few control experiments to validate the “new” torque machine. Did a set of color learning and also isolated operant self learning. They do behave as expected. There is a small lumping together in the data the first period after the optomotor response in which the flies are in a neautral setting. It should be noted that it is a combined experiments of alternating right and left optomotor response. Also, the data in this figure is also a combination of the A/D converted “correctly” installed and “incorrectly”, i.e. inverted and reversed.

Each period is set to 120 seconds, meaning that the flies are getting a total of 8 minutes of training. The flies are performing two initial pre-tests, one test after 4 minutes of training and two final test periods. For the entire duration of the experiments flies are given a color indication if they are being punished or not as a result of left or right turning, this is a composite learning control. For the final test periods the colors have been removed, meaning that we are isolating the operant component. This is different from the previous tests that has been done where flies were not challenged with colors but just relied on their own behavior to determine which side is being punished. A removal of the helping colors resulted in a lack of preference for left- or right-turning maneuvers.
