Locus ceruleus : ウィキペディア英語版
Locus coeruleus

The locus coeruleus (\-si-ˈrü-lē-əs\, also spelled locus caeruleus or locus ceruleus) is a nucleus in the pons (part of the brainstem) involved with physiological responses to stress and panic.
The locus coeruleus is the principal site for brain synthesis of norepinephrine (noradrenaline). The locus coeruleus and the areas of the body affected by the norepinephrine it produces are described collectively as the locus coeruleus-noradrenergic system or LC-NA system.〔
〕 Norepinephrine may also be released directly into the blood from the adrenal medulla.
==Anatomy==

The locus coeruleus (or "LC") is located in the posterior area of the rostral pons in the lateral floor of the fourth ventricle. It is composed of mostly medium-size neurons. Melanin granules inside the neurons of the LC contribute to its blue color. Thus, it is also known as the nucleus pigmentosus pontis, meaning "heavily pigmented nucleus of the pons." The neuromelanin is formed by the polymerization of noradrenaline and is analogous to the black dopamine-based neuromelanin in the substantia nigra.
In adult humans (19-78) the locus coeruleus has 22,000 to 51,000 total pigmented neurons that range in size between 31,000 and 60,000 μm3.
