Extended Data Fig. 1: Velocity – acceleration profiles of freely behaving mice.
(a) Schematic of the method used to calculate velocities and accelerations in the mouse’s coordinate frame from marker-less tracking data. (b) Example data of velocity and acceleration time series in the mouse’s x axis (forwards/backwards). (c) Velocity-acceleration profile of the data in (b). (d) Close-up view of a 20 s clip (blue trace) of the data in (b), with two periods of motion highlighted (orange and yellow traces). (e) Velocity-acceleration profiles of the data in (d). (f) Example data of velocity and acceleration time series in the mouse’s y (lateral) and yaw (rotation left and right) axes (top, y; bottom, yaw). (g) Velocity-acceleration profiles of the data in (f), (top, y; bottom, yaw). (h) Close-up view of a 15 s clip of the data in (f), with two periods of motion highlighted (purple and green traces). (i) Velocity-acceleration profile of the data in (h).
