A, quantitative EEG spectral analysis in the rat sensorimotor cortex: effects of SL651498 and diazepam. Statistically significant increases (% variations) of absolute percent of total power values for each frequency band and total power after increasing doses of SL651498 (3, 10, and 30 mg/kg) or diazepam (0.3, 1 and 3 mg/kg) in rats; B, effects of SL651498 on sleep-wakefulness cycle in rats recorded during the dark period: global analysis of a 6-h period. n = 6.

  • N.S., not significant; W, wakefulness; SWS, slow wave sleep; PS, paradoxical sleep; nPS, number of PS phases; xPS, mean duration of PS phases; PS lat, delay of the onset of the first PS phase.
