Extended Data Fig. 7: Results are not dependent on time-warping.

In this figure, we reproduce some of the key analyses of the paper after aligning trials by ‘trimming’ to a fixed duration rather than the time-warping used in the main text. (a) Neural similarity as a function of time difference for neurons recorded for at least 14 days in the lever-pressing task in either DLS (blue) or motor cortex (red). Note the similarity with Fig. 4c using time-warping. Lines and shading indicate mean and standard error across units. (b) Kinematic similarity in the lever-pressing task as a function of time difference across all animals. Solid line and shading indicate mean and standard error across animals after trimming. Dashed line indicates the mean after time-warping. Note that time-warping better aligns kinematics, which is the primary motivation for its use in the main text. (c) correlation between neural similarity and kinematic similarity on consecutive days (c.f. Fig. 5d). (d-f) As in a-c, now for the wet-dog shake behavior.
