medial parabrachial nucleus
Acronym: MPB
The term medial parabrachial nucleus refers to one of three or four components (in different species) of the parabrachial nuclei of the pontine tegmentum. It is located adjacent to the medial surface of the superior cerebellar peduncle of the pons. In the human ( Paxinos-2012 ) and the macaque ( Paxinos-2009a ) an external part is identified separately. Some authors subdivide it similarly in the rat ( Paxinos-2009b ) and mouse ( Franklin-2008 ).
     Functionally it is divided into three parts in the rat: medial medial, external medial, and ventral medial parts ( Swanson-2004 ). The comparable segmentation in the mouse includes only medial medial and external medial parts ( Dong-2004 ). Functionally the nucleus belongs to the viscerosensory nuclei ( Swanson-2004 ).
