Experimental reconstruction of the phase space by means of an embedding. (a) Averaged time series of en in response to temporal perturbations T of all sizes and signs. (b) Embedding of the time series shown in (a). The trajectories are organized in phase space according to the size and sign of perturbation (the smallest perturbations ±15 ms follow the same organization than the larger ones but are visually masked by the post-perturbation variability). The beginning of each trajectory is marked by a dot and corresponds to the perturbation step n = 0 in the time series (steps before the perturbation are not shown for visual clarity). All trajectories converge to the origin, representing the post-perturbation baseline. Mean across subjects; the error bands are not shown for visual clarity.
