Fig. 5.

Diffusive-like exploration of the behavioral manifold for individual fish. A Two qualitatively different trajectories from the same fish at the same temperature (26 C), recorded at 1h interval. B, C Coefficients of the two first principal components for 18 different fish (one color corresponds to one fish). The solid line is the PC coefficients computed from the multi-fish experiments as shown in Fig. 4E and F. D Time-evolution of the projections in the 2D PCA space from an example fish. One dot corresponds to one trajectory whose parameters are projected on the multi-fish PC space. Color encodes the time at which the trajectory starts. Arrows show trajectories represented in A with the same color. Autocorrelation function of the projections on E PC1 and F PC2, averaged across fish. Gray area is the standard error of the mean. Red line is the autocorrelation function of a simulated Ornstein–Uhlenbeck process whose bias parameter (1/τ) is fitted to the data
