Most of our behavioral and physiological activities are modulated or regulated by endogenous clocks, chief among them the circadian (i.e., about a day) clock. Optimally located in the suprachiasmatic nuclei (SCN) of the anterior hypothalamus [1, 2], the circadian pacemaker in the SCN receives light information via the retinohypothalamic tract [3] directly from the retina’s classical and nonclassical photoreceptors [4–6]. This light input is crucial, since circadian rhythms need to be entrained… CONTINUE READING
