ResumoSleep/waking stages and EEG power spectra were studied in rats for 8 h following intraperitoneal administration of CGS 12066B, a selective 5-HT1B agonist. Waking was increased and rapid eye movement (REM) sleep decreased in a dose-dependent manner. Total slow-wave sleep (TSWS) was reduced, but only in the first 2 h period. The latencies to REM sleep and stable sleep were increased dose-dependently. The drug also induced profound behavioural changes that may account for some of the sleep/waking changes. EEG power densities in waking and TSWS were reduced dose-dependently from 7 to 20 Hz after CGS 12066B, suggesting a tendency towards general deactivation. The increase in waking together with a general deactivation suggest complex effects of CGS 12066B on the sleep/waking axis.
