Noradrenergic cell group A1 is a group of cells in the vicinity of the
lateral reticular nucleus
The lateral reticular nucleus, of the lateral funiculus, can be divided into three subnuclei, the parvocellular, magnocellular and the ''subtrigeminal''. As is typical of the reticular formation, none of these are very distinct subnuclei, but rat ...
of the
medullary reticular formation
The reticular formation is a set of interconnected nuclei that are located throughout the brainstem. It is not anatomically well defined, because it includes neurons located in different parts of the brain. The neurons of the reticular formation ...
