Locus coeruleus and its influence pathways
The locus coeruleus (/sɪˈruːliəs/) (LC), also spelled locus caeruleus or locus ceruleus,[1] is a nucleus in the pons of the brainstem involved with physiological responses to stress and panic.[2] It is a part of the reticular activating system.
The locus coeruleus, which in Latin means "blue spot", 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.[3] Norepinephrine may also be released directly into the blood from the adrenal medulla.
