However, after sleep, there was a strong and highly significant change in the time to peak of the PETH (i.e., “temporal coupling shift,” Fig 3B , Kolmogorov-Smirnoff p < 0.001) and a smaller but significant change in task-related modulation ( Fig 3C , p < 0.05, paired t test comparing modulation for Reach 2early to both Reach 1 blocks).
