The suprachiasmatic nucleus [PDF]
Current Biology, 2018 Like it or not, your two suprachiasmatic nuclei (SCN) govern your life: from when you wake up and fall asleep, to when you feel hungry or can best concentrate. Each is composed of approximately 10,000 tightly interconnected neurons, and the pair sit astride the mid-line third ventricle of the hypothalamus, immediately dorsal to the optic chiasm (Figure

Immunohistochemical Identification of Oxytocin Neurons in the Suprachiasmatic Nucleus of the Male and Female Albino Rats: A Morphometrical Study [PDF]
The Egyptian Journal of Histology, 2019 Background: The suprachiasmatic nucleus (SCN) is one of the nuclei in the anterior hypothalamus superior to the optic chiasma. It is well known that vasopressin and oxytocin neurons are located in the hypothalamic para-ventricular and the supraoptic ...

Nature Communications, 2021 It is unclear how circadian signals from the suprachiasmatic nucleus (SCN) are decoded to generate daily rhythms in hormone release. Here, the authors show that daily corticosterone release depends on coordinated clock gene and neuronal activity rhythms ...

A Journey in the Brain’s Clock: In Vivo Veritas?
Biology, 2023 The suprachiasmatic nuclei (SCN) of the hypothalamus contain the circadian pacemaker that coordinates mammalian rhythms in tune with the day-night cycle.

Nature Communications, 2020 Cell groups in the hypothalamic suprachiasmatic clock contribute to the genesis of circadian rhythms. The authors identified two populations of vasoactive intestinal polypeptide-expressing neurons in the suprachiasmatic nucleus which regulate locomotor ...

Long-lasting effects of sepsis on circadian rhythms in the mouse. [PDF]
PLoS ONE, 2012 Daily patterns of activity and physiology are termed circadian rhythms and are driven primarily by an endogenous biological timekeeping system, with the master clock located in the suprachiasmatic nucleus.

Masking effect in rats bearing partial lesions of the suprachiasmatic nucleus
Sleep Science, 2010 Background and objective: To explore the role of the suprachiasmatic nucleus (SCN) for masking by light in rats bearing bilateral complete or partial lesions of the suprachiasmatic nucleus. Methods: Rats were submitted to electrolytic SCN

Ablation of microglia does not alter circadian rhythm of locomotor activity
Molecular Brain, 2023 Microglia, as macrophages in the brain, are responsible for immune responses and synaptic remodeling. Although the function of microglia is regulated by circadian rhythms, it is still unclear whether microglia are involved in the generation and light ...

Cell Reports, 2019 Summary: Daily adaptation of metabolic activity to light-dark cycles to maintain homeostasis is controlled by hypothalamic nuclei receiving information from the retina and from nutritional inputs that vary according to feeding cycles.
