Here we show that the expectation that sleep will come to an end at a certain time induces a marked increase in the concentration of the hormone adrenocorticotriopin(促肾上腺皮质激素) in the blood one hour before waking. The regulation of adrenocorticotropin release during nocturnal sleep is therefore not confined to daily rhythms._________(46).
_________(47). Normally, the release of adrenocorticotropin and cortisol(皮质醇) increases during late stages of sleeping, reaching a daily maximum at the time of spontaneous waking.
