Figure 3.

Pie charts presenting the mean percentage of time spent in wakefulness, quiet sleep, and active sleep during the first hour (top) and the 3 hr recording period (bottom) after the combined injection of muscimol and carbachol or saline and carbachol, respectively. Data within parentheses are means ± SEM. Compared with the percentages observed after the injection of saline and carbachol (n = 6), the injection of muscimol and carbachol significantly increased the percentage of time spent in wakefulness (p < 0.01) and significantly decreased the percentage of time spent in active sleep (p < 0.01) during the first hour of recording. During the entire 3 hr recording period, the injection of muscimol and carbachol also induced significant changes in the percentage of time spent in wakefulness (p < 0.01) and active sleep (p < 0.01).
