title: The influence of the light-dark and wake-sleep cycles on preoptic cAMP concentration in the rat.
abstract: The concentration of cAMP was measured in the preoptic region of rats sleeping at normal laboratory conditions (12:12 h LD, Ta 22 +/- 0.5 degrees C). The results show that the nucleotide concentration changed both during the circadian LD cycle and during the ultradian wake-sleep cycle.
