Daily rhythmicity in neuroendocrine functions and sleep-wake cycle is controlled by an endogenous circadian timing system, organized in a network of oscillatory structures. At the top of this circadian multi-oscillatory network, there is a master clock located in the suprachiasmatic nuclei of the hypothalamus. The molecular clockwork involves various clock genes, such as Period (Per).Light is the most potent synchronizer of the suprachiasmatic clock. By ...
