Abstract:
:Rats with suprachiasmatic nuclei (SCN) lesions did not show increased sleep after triazolam (TRZ) injections at any dose from 0.2 to 1.6 mg/kg, whereas 0.4 mg/kg TRZ given intact rats in the middle of their activity phase significantly increased sleep. Across SCN-lesioned and intact rats, the amount of sleep before and after TRZ 0.4 mg/kg was negatively correlated. SCN-lesioned rats did not have a circadian activity-dominant period and so did not accumulate a biological sleep debt. Their lack of response to TRZ may have resulted from the absence of a sleep debt compared to intact rats injected in the middle of their activity phase. These data support our hypothesis that the homeostatic process controlling sleep gates benzodiazepine hypnotic efficacy.
