genu of the corpus callosum

genu of the corpus callosum (ccg)

The term genu of the corpus callosum (ccg) refers to the rostral most portion of the corpus callosum (cc) in the human ( Carpenter-1983 ), macaque ( Martin-2000 ), rat ( Swanson-2004 ) and mouse ( Franklin-2008 ). It is bounded caudally by the body of the corpus callosum (ccb), and, in all but the mouse, ventrocaudally by the rostrum of the corpus callosum (ccr). It is Region 2 of seven parts defined in a common parcellation scheme for the corpus callosum. See corpus callosum (Witelson). Updated 21 Aug 2024.

Also known as: corpus callosum, genu, genu of the corpus callosum, genu of corpus callosum, Genu corpus callosi, Corpus callosum, genu, Genu corporis callosi, rostrum of corpus callosum (Mai), genu, Region 2

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.

Functional CNS Model - Rat

The Functional CNS Model - Rat (FMrat) ( Swanson-2004) is one of three hierarchical models representing the internal organization of the central nervous system (CNS). The others are the Structural CNS Model - Human (SThmn) and the Functional CNS Model - Human (FMhmn). The FMrat model represents the basic organization of the mouse ( Hof-2000 AMBA-2024 ) and, presumably, other rodents. Functional CNS models differ from structural models in that structures are defined and named by connectivity rather than by proximity to other structures at the same level. Functional models are more useful for representing longitudinal components of are grouped based on information drawn from multiple neuroscientific disciplines. such as connections, neurochemical characteristics, and role in physiogical and behavioral processes. While the Functional Model was developed primarily for an atlas of the rat brain ( Swanson-2004 ), the hierarchical organization of structures is for the most part applicable to the human, macaque, mouse and other mammalian brains as well. Structures at lower levels of the Functional CNS hierarchy are largely the same as in the Classical and Developmental Models, i.e., they were originally identified by stains for gray matter (Nissl substance) and white matter (myelin). At the next higher level they are grouped into basic connectional and functional systems of the CNS, such as the subcortical sensory systems, the brainstem motor system and the behavioral state system. At the highest levels CNS structures are grouped on the basis of dissection and embryologic precursors into cerebrum ( cerebral cortex and cerebral nuclei ), cerebellum, and cerebrospinal trunk.
