Extended Data Figure 4: Learning did not improve over sessions.
It might have been that, over the course of weeks and months, the animals improved at learning to use perturbed mappings, either one type or both types together. This did not occur. Within-manifold perturbations showed more learning than outside-manifold perturbations across the duration of experiments. Animals did not get better at learning to use either type of perturbation separately (red and blue regression lines, F-test, P > 0.05 for all relationships) nor when considering all sessions together (black regression line, F-test for linear regression, P > 0.05). Same number of sessions as in Extended Data Fig. 2. Each point corresponds to one session.
