Neuronal Input Pathways to the Brain’s Biological Clock and their Functional Significance
X, 76 p. 22 illus., 13 illus. in color. online resource.
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.
Introduction -- The suprachiasmatic nucleus (SCN) -- The endogenous rhythm of the SCN -- The SCN molecular clock -- Photic regulation of the circadian rhythm -- Retinal input – Neuroanatomy -- Neurotransmitters in the RHT -- Glutamate and PACAP -- Other neurotransmitters of the RHT -- RHT neurotransmitter receptors in the SCN.-Melanopsin - an irradiance detecting photopigment of the RHT -- Retinal input - Physiology -- Non-photic regulation of the circadian rhythms -- Midbrain raphe input - Neuroanatomy -- 5-HT and regulation of the circadian system -- The intergeniculate leaflet and the geniculohypothalamic tract – neuroanatomy -- Effects of NPY on circadian rhythm during subjective day -- NPY modulates light-induced phase shift during subjective night -- Summary.
