Effects of stressor and three different doses of zolpidem on REM sleep. Bars represent percentages (mean + SE) of REM sleep during each of the 6-h periods after following treatments: non-shocked vehicle-injected (C-NS), shocked and vehicle-injected (C-S), shocked and 1 mg/kg dose of zolpidem-injected (S-Zol-1), shocked and 3 mg/kg dose of zolpidem-injected (S-Zol-3), and shocked and 10 mg/kg dose of zolpidem-injected (S-Zol-10). *Comparisons with non-shocked vehicle-injected (C-NS) and Δcomparisons with shocked and vehicle-injected (S-C). Δ: p<0.05; ** or ΔΔ: p<0.01; *** or ΔΔΔ: p<0.001.
