pons - BrainInfo

pons (PON)

The term pons (PON) refers to one of two parts of the metabrain (MTB). Defined by dissection, it is bounded from the midbrain (MBR) rostrally by a nominally oblique plane, which passes from the caudal margin of the inferior colliculus (IFC) to the rostral margin of the basal pons (PONb) ventrally. Caudally, it is bounded from the medulla (MDL) by a similar plane, which passes from the middle cerebellar peduncle (mcp) dorsally to the caudal margin of PONb) ventrally. It is connected to the cerebellum (CBL) dorsally by the cerebellar peduncles. It is found in the human ( Carpenter-1983 ), macaque ( Shantha-1968 ), rat and mouse ( NeuroNames ).

Also known as: pons, Pons, Pons Varolii, pons cerebri, Metencephalon, anterior hindbrain, isthmic organizer

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.

Classical Vertebrate Central Nervous System

The Classical Vertebrate Central Nervous System is a hierarchical model of gray matter structures that are common to the brain and spinal cord of all vertebrates. As in other classical models, structures are grouped by proximity as observed on dissection, and the upper levels correspond roughly to their organization in the embryo. The hierarchical organization is based on the Basic Partts List for Adult Nervous System in All Animals ( Swanson-2104 ), the nomenclature on NeuroNames ( Bowden-2012 ).
