What is the most impoant source of noradrenergic innervation to the cerebral coex?
The locus coeruleus is a dense collection of neuromelanin-containing cells in the rostral pons, near the lateral edge of the floor of the fouh ventricle. The fact that it appears blue-black in unstained brain tissue gave rise to its name, which means "blue spot" in Latin. These cells, which contain norepinephrine, provide the majority of noradrenergic innervation to the forebrain, including the cerebral coex.
