The suprachiasmatic nucleus (SCN) of the hypothalamus is remarkable. Despite numbering
only about 10,000 neurons on each side of the third ventricle, the SCN is our principal …

The suprachiasmatic nucleus (SCN) is the principal circadian clock of the brain, directing
daily cycles of behavior and physiology. SCN neurons contain a cell-autonomous …

Light is the most important Zeitgeber for entraining animal activity rhythms to the 24-h day. In
all animals, the eyes are the main visual organs that are not only responsible for motion and …

The hypothalamic suprachiasmatic nuclei (SCN) are the principal mammalian circadian
timekeeper, co-ordinating organism-wide daily and seasonal rhythms. To achieve this, cell …

Critical physiological processes such as sleep and stress that underscore health are
regulated by an intimate interplay between the endocrine and nervous systems. Here, we …

It has been 50 years since the suprachiasmatic nucleus (SCN) was first identified as the
central circadian clock and 25 years since the last overview of developments in the field was …

The circadian system constrains an organism's palette of behaviors to portions of the solar
day appropriate to its ecological niche. The central light-entrained clock in the …

Circadian rhythms in mammals are coordinated by the suprachiasmatic nucleus (SCN). SCN
neurons define circadian time using transcriptional/posttranslational feedback loops (TTFL) …

Regular exercise is important for physical and mental health. An underexplored and
intriguing property of exercise is its actions on the body's 24 h or circadian rhythms …

The suprachiasmatic nucleus (SCN) is composed of functionally distinct subpopulations of
GABAergic neurons which form a neural network responsible for synchronizing most …
