Dose-dependent decreases in REM sleep and increases in non-REM sleep in the first hour after microinjection of 5-HT into the LDT nuclei in five rats
| Intervention | % REM | % non-REM |
|---|---|---|
| 1.5 mm 5-HT | 16.3 ± 3.9* | 81.1 ± 4.6* |
| 1.0 mm 5-HT | 21.8 ± 2.4 | 73.8 ± 3.2 |
| Saline | 27.7 ± 1.6 | 68.4 ± 2.2 |
| Sham (i.e., no microinjection) | 26.7 ± 4.0 | 68.4 ± 3.8 |
| One-way ANOVA-RM | p = 0.037 | p = 0.025 |
Values are mean ± SEM.
