Parabigeminal nucleus

Name: Parabigeminal nucleus
Description: Cholinergic cell group that is located ventral to the brachium of the inferior colliculus (in rat) and has reciprocal connectivity with the superior colliculus (Adapted from Paxinos, The rat central nervous system, 2nd ed, 1995, pg 865
Synonym(s): Nucleus parabigeminous, Ch8 cell group[1]
Abbreviation: PBG
Is part of: midbrain tectum
Super-category: Regional part of brain
*Id: birnlex_1007

Neuronames ID ( what's this?): 473
Defining Criteria: cyto-architecture, chemoarchitecture
Cyto-architecture defining Criteria: A compact cell group that lies along the lateral margin of the mesopontine region just ventral to the brachium of the inferior colliculus. [1]
Chemoarchitecture defining Criteria: Majority of cells are cholinergic. ChAT-positive cell bodies of the parabigeminal nucleus are oval in shape and 10-20/um in diameter, as measured in mouse. [1]
Brain regions that receive axons from this region: Superior colliculus [1]
