Journal ArticleDOI
Anatomical demonstration of the suprachiasmatic nucleus-pineal pathway.
TL;DR: In this article, a polysynaptic pathway is proposed to transmit light information from the retina through the suprachiasmatic nucleus of the hypothalamus (SCN) to the pineal.
Journal ArticleDOI
Efferent projections of the suprachiasmatic nucleus in the golden hamster (Mesocricetus auratus)
TL;DR: A pronounced innervation of the contralateral SCN was observed, of which the neurotransmitter remains to be established, and Pha‐L tracing indicated the existence of SCN projections which could not be ascribed to one of the presently investigated peptides.
Journal ArticleDOI
Direct vasoactive intestinal polypeptide-containing projection from the suprachiasmatic nucleus to spinal projecting hypothalamic paraventricular neurons.
TL;DR: Investigating whether SCN efferents containing vasoactive intestinal polypeptide (VIP) innervate PVN neurons that project to the spinal cord provided further evidence for the involvement of SCN-derived VIP in the transmission of circadian information to the pineal.
Journal ArticleDOI
In Syrian and European hamsters, the duration of sensitive phase to light of the suprachiasmatic nuclei depends on the photoperiod
TL;DR: It is observed that the duration of the photosensitive phase is variable and tied to the length of the night, and a maximal extension has been determined in both species studied.

Chapter 24 The suprachiasmastic nucleus: the biological clock of all seasons

TL;DR: The data presented in this chapter demonstrates that SCN activity is not only cued by the light/dark cycle but also strongly influenced by the photoperiod, and indicates that the currently accepted separation between the circadian and seasonal photo-timing system is perhaps not justified on the physiological grounds.
