caudal pontine reticular nucleus

caudal pontine reticular nucleus (PRNc)

The term caudal pontine reticular nucleus (PRNc) refers to one of three components of the pontine reticular nuclei (PRN) ( Carpenter-1983 ). Identified by histology, it is variously described as continuous across the midline or bounded medially by the raphe nuclei (histological) (RPHhis) and the tegmental reticular nucleus (RPHtg). It is bounded dorsomedially by the medial longitudinal fasciculus of the pons (mlfp), ventromedially by the trapezoid body (tpz) and ventrolaterally by the superior olivary complex (OLVicx). The remainder of its boundaries are defined by several smaller reticular and cranial nerve nuclei. It is bounded rostrally by the rostral pontine reticular nucleus (PRNr) and caudally by the central medullary reticular group (MRNc). It is found in the human ( Carpenter-1983 ), the macaque ( Martin-2000 ), the rat ( Swanson-2004 ) and the mouse ( Hof-2000 ). Some authors distinguish the most ventromedial portion as the ventral part of the pontine reticular nuclei (PRNv) ( Hof-2000; Paxinos-2009b ). In the rat the majority of noradrenergic neurons of the A5 cell group are located in this nucleus. Functionally it belongs to the reticular formation (functional) of the brainstem motor system ( Swanson-2004 ). Updated 24 Oct 2025.

Also known as: caudal pontine reticular nucleus, Nucleus reticularis pontis caudalis, Nucleus reticularis pontis, pars caudalis, pontine reticular nucleus, caudal part, pontine reticular nucleus caudal part

Models Where It Appears

Structural CNS Model - Macaque

Brain structures of the macaque are illustrated in BrainInfo’s NeuroMaps macaque brain atlas. Structures are grouped by proximity in a hierarchy corresponding to the central nervous system hierarchy of NeuroNames ( Bowden-1995 Martin-2000 ). Structures in the NeuroMaps atlas are based on the segmentation of an MRI of the brain of a 3-year old male rhesus macaque (Macaca mulatta). The atlas is most useful for targeting structures for implantating electrodes and chemtrodes. Updated 29 Oct 2025.
