Abstract
Although most pituitary hormones are producedin pulsatile sequences of varying frequencies, a fairly stable circadian secretory pattern usually emerges from this episodic background. This raises the first basic question applying to all circadian rhythms, as to whether neuroendocrine circadian rhythms are primarily driven by an endogenous, environmentally entrained oscillator or circadian pacemaker. So far, the existence of such a pacemaker generating an overt neuroendocrine rhythm has only been clearly demonstrated in the pineal (Moore and Klein 1974) and in the adrenocorticotropic system. For the latter, the period of freerunning Cortisol rhythm was thus estimated at 24.8 h in blind men (Wever 1979), and for freerunning ACTH and corticosterone rhythms, it ranged from 24.2 h to 24.4 h in blind or dark-housed (DD) rats (Szafarczyk et al. 1980a, 1981b).
