Results of the T-maze screen analysis, both individual and combined.

Yellow 1 (Positive Control): Gr28bd-G4, TrpA1-G4

Parameters: Light: intensity (500 Lux side, 1000 Lux bottom); frequency = 20Hz; Delay = 1 ms; Duration = 9.9 ms; volts = 6.4

## The T-Maze experiments : Middle analysis and Correlation plot

on Saturday, July 14th, 2018 12:06 | by Naman Agrawal

The mean ratio of the flies that stay in the middle during the experiments.

Correlation plot between the mean ratio of the flies that stay in the middle versus the Weighted PIs

Slope = 0.0053

Intercept = 0.240

R square value = -0.03834

contrary to the expectations, there seems to be no correlation .

## Modelling the valence of dopaminergic clusters from the Y-mazes

on Monday, June 25th, 2018 1:52 | by Christian Rohrsen

Dopaminergic clusters are differently targeted by the different Gal4s. Some of the express faintly, others stronger. Here I try to see if the dose-response curve (or expression-PI curve) seems to be linear or not. Here I put two examples from the 17 clusters, where the first two seem to have nonlinear curves, with and optimal expression level, and the last two seem to have a linear response curve.

This will be important for the modelling in order to decide to make a linear/nonlinear model. Down below I show the results from a linear model and it´s statistics. From Aso et al. 2012, one could see that activating the lines with TrpA1 shows a linear response curve. But in this case it does not necessarily seem to be the case. Therefore, light intensities might have an effect, as well as the expression level, and conclusion needs to be taken carefully.

In addition it is difficult to calculate this for all the clusters with just one single light intensity test, because not all clusters are expressed in several Gal4s to different level, so that we can estimate from there. So for the interesting lines we might need to make several experiments at different intensities, and see the dose response curve.

The G4s I have used for the modelling are the ones shown here.

## Making new ratios for Y-maze

on Monday, June 18th, 2018 1:55 | by Christian Rohrsen

This is just to show that I am trying to find a new ratio so that all graphs have from -1 to +1 ranges. That is why now the difference in occupancy time is divided by the total time. The same with the speed. Because speed differences are so subtle, the Y axis scale has to be lower

## Tmaze experiments initial results

on Monday, June 4th, 2018 2:16 | by Naman Agrawal

the first graph shows Bar plot of Mean and standard deviation of PIs for Genetic control (n=9) and Positive control (n=5).

The second graph shows weighted mean and weighted standard deviation of the same.

Weighted mean is calculated by multiplying the weights (total number of flies in that experiment/total number of flies in all the experiments) with the PI for that experiment, and taking the sum thereafter for all the experiments.
