Figure 4

Slow wave sleep (SWS) and paradoxical sleep (PS) rebound during recovery. (A,B) Upper (SWS) and lower panel (PS) show sleep time in minutes cumulated over 2 h intervals during recovery day R1 and R2 (cage off at t = 17:00 on R1, n = 6 per group, values for quiet control [QC] reported from D14). (C,D) Slow wave activity (SWA) normalized by last 2 h of sleep of R2 calculated for equal sleep intervals (4 in dark phase, 8 in light phase). (E–H) SWS and PS total and bout time cumulated over 12 h. Note significant quantitative SWS and PS rebound during the dark phase around 23:00 and significant qualitative rebound including SWA and bout consolidation throughout R1 with complete resolution on R2. Horizontal black bars and asterisks indicate significance (P < 0.05, Tukey post-analysis of variance versus QC and motor control).
