Statistical signature of subtle behavioral changes in large-scale assays
Fig 5
(A) Graphical representation of the probabilistic generative model, showing the temporally inhomogeneous Poisson model , the distribution of action amplitudes
, and transition probabilities to the other actions.
(B) characterization of behavioral responses to an air puff with the prediction of the generative model for two lines. At the top: time evolution of the larva’s actions; thin lines represent the experimental recording, and thick lines are the generative model. At the bottom, a circular plot of the z-scores between the action sequences of the generative model and the experimental recordings. Darker blue colors indicate larger values. The two lines are R41D01 on top and R38H09 on the bottom.
