orbital gyri (ORG)

The term orbital gyri (ORG) refers to a set of convolutions on the ventral surface of the frontal lobe (FLB) in primates. It is defined by topology ( Nomina-1983 ). In the human it consists of five gyri: the medial orbital gyrus (ORGm), the anterior orbital gyrus (ORGa), the posterior orbital gyrus (ORGp), the lateral orbital gyrus (ORGl), and the frontomarginal gyrus (ORGfm) ( Mai-1997 ). The macaque has the same, except that it lacks the ORGfm ( Martin-2000 ). Final 21 Jan 2025.

Also known as: orbitofrontal cortex, Cortex orbitofrontalis, Gyrus orbitalis, gyrus orbitalis longitudinalis, orbital gyri, Gyri orbitales, orbitofrontal gyri, orbitofrontal gyrus, orbital cortex, orbital area, orbitofrontal region

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.
