This region, called the suprachiasmatic nucleus or SCN, is just above the optic nerve on both sides of the brain.
Human circadian rhythms are controlled by a region of the brain called the suprachiasmatic nucleus, or SCN, which is located in the hypothalamus, a region of the brain that regulates many of the tasks of the autonomic nervous system.
For a few decades neuroscientists have known that circadian rhythms, the sleep and alertness cycles that we experience every day, are controlled by a part of the brain in the hypothalamus called the SCN suprachiasmatic nucleus.
Consistent with the behavioral deficits, light-induced phosphorylation of extracellular signal-regulated kinase 1/2 (ERK) in the SCN, which is suggested to be a highly sensitive light detector and a determinant of the magnitude of phase delay
The SCN, which is located in the hypothalamus in the brain, transmits information taken from the retina to the pineal gland.
I caught part of this documentary on snakes last night on SCN.
The Pearson theory of hard and soft ligands and metals was new and fashionable at the time, so Prof. Kline wanted me to find out if thiocyanate could simultaneously bind with its "soft" sulfur to a soft metal and its "hard" nitrogen to a hard metal, e.g. PhHg – SCN – Cr (III).
My first exposure to a research environment was in a National Science Foundation-sponsored summer research program at Ohio University in 1967, where I was assigned to work in the laboratory of Prof. Robert Kline on the ambident coordination of thiocyanate (SCN –).
All of these clocks are controlled by the master pacemaker of the hypothalamic suprachiasmatic nuclei (SCN), which synchronizes all of the body's "peripheral" clocks with the outside world.
Destruction of the SCN results in the complete absence of a regular sleep/wake rhythm.
