Circadian Rhythm

Circadian Rhythm is the regular recurrence, in cycles of about 24 hours, of biological processes or activities, such as sensitivity to drugs and stimuli, hormone secretion, sleeping, feeding, etc. This rhythm seems to be set by a 'biological clock' which seems to be set by recurring daylight and darkness.

How Does the Suprachiasmatic Nucleus (SCN) Control Circadian Rhythm?

Circadian rhythms are biological cycles within organisms that allow them to adjust their physiology and behavior to anticipate and adapt to changes in the outside environment. Circadian rhythms are maintained with the help of circadian clocks, the main circadian clock in mammals is the suprachiasmatic nucleus (SCN).

Study uncovers new rules for lineage progression

The hypothalamus, one of the most complex brain regions in the mammalian nervous system, contains an astonishing heterogeneity of neurons that regulate endocrine, autonomic and behavioral functions. It not only regulates food consumption, water intake, body temperature, circadian rhythm and sleep to maintain the survival of individual organisms, but also controls puberty onset and reproductive behavior to sustain the breeding population.
