REM sleep-active, wake/REM-active and state-indifferent neurons in the LPO. A: mean baseline sleep-wake DR (±SEM) for the different LPO cell types that were studied under conditions of baseline, SD and RS. There was a significant overall effect of sleep-waking state on the discharge of REM-active neurons [F(15,2) = 39.7, P < 0.001], on the discharge of wake/REM-active neurons [F(27,2) = 14.9, P < 0.001], but not on the discharge of state-indifferent neurons [F(13,2) = 1.0, ns]. Significantly different from all other values, *P < 0.05; **P < 0.01. Holm-Sidak test. B: drawing of a coronal section at the level of the preoptic hypothalamus showing the locations of REM-related neurons (black circles), wake/REM-active neurons (gray circles) and state-indifferent neurons (open circles).
