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 …

Biological clocks are autonomous anticipatory oscillators that play a critical role in the
organization and information processing from genome to whole organisms. Transformative …

How obesity and elevated androgen levels in women with polycystic ovary syndrome
(PCOS) affect their offspring is unclear. In a Swedish nationwide register-based cohort and a …

Circadian rhythms (CR) are a series of endogenous autonomous oscillators generated by
the molecular circadian clock which acting on coordinating internal time with the external …

The circadian system serves one of the most fundamental properties present in nearly all
organisms: it generates 24-h rhythms in behavioral and physiological processes and …

Circadian rhythms are 24-h rhythms in physiology and behaviour generated by molecular
clocks, which serve to coordinate internal time with the external world. The circadian system …

Light around twilight provides the primary entrainment signal for circadian rhythms. Here we
review the mechanisms and responses of the mouse and human circadian systems to light …

The accumulation of adenosine is strongly correlated with the need for sleep and the
detection of sleep pressure is antagonised by caffeine. Caffeine also affects the circadian …

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 …

The hypothalamic suprachiasmatic (SCN) clock contains several neurochemically defined
cell groups that contribute to the genesis of circadian rhythms. Using cell-specific and …
