a. Weights of the regression model to predict neural auditory PC1 from motion PCs (z-scored motion PC1 weights only are shown) for each individual mice (gray) and the average across mice (black). The model was computed on the spontaneous (no stimulus) period for the visual cortex experiments (Fig. 1). b. Distribution of the delay to the peak of the weights. A positive delay means that movement precedes and predicts neural activity by such a delay. c, d. Same as a, b, but for recordings in the HPF (Fig. 2). e,f. Same as a, b, but for recordings in visual cortex during the transectomy experiment (Fig. 3) (both sides).
