Extended Data Fig. 6. Additional data: movement decoding-based controls for the alignment procedure.

(a) Predictive accuracy when decoding hand velocity for all pairs of days from Monkey C_L, using the unaligned latent dynamics as inputs instead of the multiunit activity used in Fig. 5. (b) Predictive accuracy when using as inputs the latent dynamics within-day, and across-day both before and after alignment, for Monkeys C_L, C_R, and M. *** denotes p < 0.001, two-sided Wilcoxon rank-sum test. Error bars: mean ± s.d. N: number of across-day comparisons.
