The locus caeruleus is a nuclear region in the upper portion of the Rhomboid fossa and shimmers bluish through its floor.
Anatomy
The locus caeruleus predominantly contains noradrenergic neurons, but also peptidergic neurons, such as those containing enkephalin or neurotensin[^1].
Projections
The neurons of the locus caeruleus project to the Hypothalamus, the limbic system, and the neocortex[^1].
