hindbrain (HBR)

The term hindbrain (HBR) refers to one ot four components of the brain as defined by surgical dissection. The others are the forebrain (FBR) and midbrain (MBR) rostral to it and the medulla (MDL) caudal to it. Its rostral boundary with the MBR is a nominally coronal plane located at the caudal margin of the inferior colliculus (ICL) dorsally and the rostral margin of the basal pons (PONb) ventrally. The caudal boundary with the MDL is defined by a nominally horizontal plane at the junction of the cerebral aqueduct (AQU) dorsally and caudal margin of the PONb ventrally. The hindbrain is composed of two parts, the pons (PON) and the cerebellum (CBL). Substructures of the hindbrain are derived for the most part from the embryonic Rhombencephalon ( Swanson-2015 ).

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 ).
