Identification of novel light-induced genes in the suprachiasmatic nucleus

open access: yesBMC Neuroscience, 2007
Background The transmission of information about the photic environment to the circadian clock involves a complex array of neurotransmitters, receptors, and second messenger systems.

The Role of TASK-3 Two-Pore Domain Potassium Channels in the Entrainment of Mammalian Circadian Rhythms [PDF]

open access: yes, 2014
In mammals light is the principal timing cue for alignment of physiology to the external environment. Illumination from the unrelenting 24-hour day-night cycle enters the biological system and is communicated to the master pacemaker, the suprachiasmatic

Loss of ZBTB20 impairs circadian output and leads to unimodal behavioral rhythms

open access: yeseLife, 2016
Many animals display morning and evening bimodal activities in the day/night cycle. However, little is known regarding the potential components involved in the regulation of bimodal behavioral rhythms in mammals.

Circadian actions of melatonin at the suprachiasmatic nucleus [PDF]

open access: yesBehavioural Brain Research, 1995
The biological clock in the suprachiasmatic nucleus (SCN) of the hypothalamus plays a well-defined role in regulating melatonin production by the pineal. Emerging evidence indicates that melatonin itself can feed back upon the SCN and thereby influence circadian functions.

Imaging Individual Differences in the Response of the Human Suprachiasmatic Area to Light

open access: yesFrontiers in Neurology, 2018
Circadian disruption is associated with poor health outcomes, including sleep and mood disorders. The suprachiasmatic nucleus (SCN) of the anterior hypothalamus acts as the master biological clock in mammals, regulating circadian rhythms throughout the ...

The VIP-VPAC2 neuropeptidergic axis is a cellular pacemaking hub of the suprachiasmatic nucleus circadian circuit

open access: yesNature Communications, 2020
Circadian activity modulation in the suprachiasmatic nucleus (SCN) is a network-level emergent property that requires neuropeptide VIP signaling, yet the precise cellular mechanisms are unknown. Patton et al.

Seasonal changes in the suprachiasmatic nucleus of man [PDF]

open access: yesNeuroscience Letters, 1992
The mammalian suprachiasmatic nucleus (SCN) is considered to be the principal component of the biological clock, generating a wide variety of physiological and behavioral circadian rhythms. In addition to its implication in circadian rhythms, the SCN is also involved in the expression of some seasonal cycles.

Retino-hypothalamic regulation of light-induced murine sleep

open access: yesFrontiers in Systems Neuroscience, 2014
The temporal organization of sleep is regulated by an interaction between the circadian clock and homeostatic processes. Light indirectly modulates sleep through its ability to phase shift and entrain the circadian clock.
