Locomotion adaptation is tested during perturbed sessions. a Throughout the perturbed sessions, the mice learned to adapt their walking patterns in response to a 15 kHz auditory stimulus preceding the appearance of an obstacle in their pathway. The obstacle, which consisted of an upward moving rung, was always located on the right side of the mouse independently of its walking direction. Its specific location depended on the predicted position of the mouse on the ladder, but was otherwise randomized. b The blue footprints represent the front paw touches of the same control and Pcd mice depicted in Fig. 3, but now during a perturbed trial. The position of the obstacle is indicated with black arrows. c Time course of the trials is depicted in b. Symbols represent single touches
