Circadian rhythmicity is controlled by a light-entrainable pacemaker located in the suprachiasmatic nuclei (SCN) of the mammalian hypothalamus. Brief light exposure during the subjective night causes phase shifts of the free-running activity rhythm and expression of c-fos-related proteins (Fos) among a population of cells in the hamster SCN. Light exposure (30 lux for 15 min) during the early subjective night (CT13) causes phase delays (-60 +/- 12 min), while exposure at mid-subjective night… CONTINUE READING
