The parvocellular reticular nucleus is part of the
brain
The brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. It consists of nervous tissue and is typically located in the head ( cephalization), usually near organs for special ...
located dorsolateral to the
caudal pontine reticular nucleus.
The dorsal portion of the reticular nucleus has been shown to innervate the
mesencephalic trigeminal nucleus and its surrounding area.
Also, it projects to the
facial nucleus,
hypoglossal nucleus
The hypoglossal nucleus is a cranial nerve nucleus, found within the medulla. Being a motor nucleus, it is close to the midline. In the open medulla, it is visible as what is known as the ''hypoglossal trigone'', a raised area (medial to the vaga ...

gigantocellular nucleus
The gigantocellular reticular nucleus (Gi) is a subregion of the medullary reticular formation. As the name indicates, it consists mainly of so-called giant neuronal cells.
This nucleus has been known to innervate the caudal hypoglossal nucleus, ...
