Long-term effects of the chronic social defeat stress on sleep-wake states in susceptible and unsusceptible mice. Amounts of vigilance states across the light/dark cycle in susceptible (A) and unsusceptible (B) mice. Amounts of wake (A1,B1), NREM sleep (A2,B2), and REM sleep (A3,B3) are expressed as minutes per 3 h across the light/dark cycle in susceptible mice (red symbols, n = 9) and in unsusceptible mice (black symbols, n = 7) at baseline (BL, open circles) and on recovery day 5 (R5, filled circles). All data, expressed in minutes per 3 h, are means ± SEM of nine susceptible and seven unsusceptible mice. **P < 0.01, significantly different from the control conditions (BL); for statistics see Table S1.
