Median reaction time (top) and slow responses (bottom) on the procedural reaction time task. Remaining aspects of figure as for Fig 2. Statistical symbols in panels A and C denote the time points at which the groups differed, following a significant group x time-of-night interaction. †(P < 0.05) and ††(P < 0.01) indicate differences between the not re-entrained and completely re-entrained groups. **indicates a difference (P < 0.01) between the not re-entrained and partially re-entrained group.
