Description of part
The parabrachial nucleus (PB) is composed of neurons which surround the superior cerebellar peduncle (SCP) along its course through the dorsolateral pons. PB has traditionally been divided into medial (PBm) and lateral (PBI) divisions and a ventrolateral extension, the Kolliker-Fuse nucleus (KF), on the basis of the description by Olszewski and Baxter of the human brainstem [37]. These same terms have been applied to the rats, although the SCP is more horizontally situated in this species so that PBl is more dorsally than laterally positioned, while PBm is oriented more ventrally than medially. Palkovits and Jacobowitz adopted the more straight forward âdorsalâ and âventralâ PB subdivisions in the rat, but this terminology obscures homologies with other species.
