Abstract
The effect of suprachiasmatic nucleus (SCN) ablation on rhythms in brain neurotransmitter receptors was studied. In control animals, the rhythms in the number of alpha-adrenergic and benzodiazepine receptors were circadian, whereas the rhythms in beta-adrenergic and acetylcholine receptors were ultradian. SCN ablation resulted in loss of circadian, but not ultradian, rhythms, without change in the 24-h mean numbers. SCN ablation appears to cause a selective loss of circadian function in the regulation of brain receptors.Entities:
