State-dependent discharge rates of sleep-active, wake/REM-active, and state-indifferent neurons during spontaneous waking and sleep
| n | Wake | Non-REM Sleep | REM Sleep | |
|---|---|---|---|---|
| Median preoptic nucleus | ||||
| Wake/REM-active | 5 | 5.7 ± 2.5 (3.3–12.5) | 3.9 ± 2.2 (2.3–8.9) | 4.8 ± 3.9 (3.3–12.4) |
| Sleep-active | 13 | 1.5 ± 0.4 (0.6–3.2) | 3.8 ± 0.6 (1.2–7.4) | 3.7 ± 0.4 (0.8–6.1) |
| State-indifferent | 7 | 4.1 ± 1.4 (1.5–16.1) | 3.8 ± 1.2 (1.2–14.4) | 4.2 ± 1.4 (1.2–24.4) |
| Lateral Preoptic Area | ||||
| Wake/REM active | 48 | 7.9 ± 0.8 (1.3–26.2) | 3.2 ± 0.4 (0.2–17.9) | 8.2 ± 1.0 (1.0–42.8) |
| Sleep-active | 26 | 5.1 ± 2.1 (0.3–12.3) | 8.2 ± 1.3 (1.5–27.9) | 8.8 ± 1.8 (1.4–32.0) |
| REM-active | 29 | 4.9 ± 1.1 (0.3–22.8) | 3.7 ± 1.0 (0.2–12.3) | 13.1 ± 2.2 (1.0–48.3) |
| State-indifferent | 25 | 20.8 ± 5.9 (1.2–47.9) | 19.3 ± 5.4 (1.2–43.8) | 19.9 ± 6.2 (1.3–44.1) |
Values are mean discharge rate (spikes/s) ± SE (range in parentheses); n, no. of rats.
REM, rapid eye movement.
