Protocol of the experiment.

<p>(A) Schematic view of the experimental protocol. All participants performed a MR practice session including a pre-training (baseline), a MR training phase, and a post-training session, to assess the effect of MR training. Then, half of the participants were re-tested following a 12 h interval including either a night of sleep (WNight/MNight) or a similar daytime period (WDay/MDay), to test the offline consolidation [Re-test/Post-training].
