About this book


Circadian rhythms are entrained daily by environmental photic and non-photic cues. The present review describes the anatomy and functional characteristics of the three major input pathways to the circadian clock mediating entrainment, the retino-hypothalamic tract (RHT), the geniculo-hypothalamic tract (GHT) and the midbrain raphe projection.
