Serotonin in the raphe nuclei: regulation by light and an endogenous pacemaker.

abstract：:Retinal light exposure induces several immediate-early genes in the hypothalamic suprachiasmatic nucleus (SCN), which contains the major circadian pacemaker of mammals. Clock-controlled and light-induced genes expressed in the SCN such as c- and contain upstream regulatory elements similar to those of the major immedi...
