Comparison of sleep-wake discharge of Type I wake-related neurons recorded in the PF-LHA and wake-related/‘REM-off’ neurons recorded in rat dorsal raphe nucleus

Area	AW (spikes s−1)	QW (spikes s−1)	Non-REM sleep (spikes s−1)	REM sleep (spikes s−1)	Decrease from wake to REM sleep (%)	Decrease from AW to QW (%)	Spike width (ms)
Dorsal raphe (n = 24)	1.09 ± 0.14	0.69 ± 0.12	0.34 ± 0.04	0.09 ± 0.02	92.6 ± 8.0	38.4 ± 4.7	2.88 ± 0.09
PF-LHA (n = 24)	4.54 ± 0.70*	1.03 ± 0.31	0.29 ± 0.09	0.37 ± 0.10	91.1 ± 1.5	77.5 ± 4.2*	2.23 ± 0.07*

Data for dorsal raphe neurons are taken from Guzman-Marin et al. (2000). All values are means ± s.e.m.
