  • For each experimental condition, the percentage of time spent in SWS, PS, and W was scored per 5 s epoch during the first 2 h (0–2 h) after injections (n = 7). The number of SWS and PS episodes, the mean duration of PS and SWS episodes, and the latency to the first SWS and PS episodes are also reported. Significance levels are given for post hoc Bonferroni-corrected Wilcoxon tests between conditions.

  • *p < 0.05 versus vehicle;

  • #p < 0.05 versus glucose 5 mm.
