lateral orbital gyrus

lateral orbital gyrus (ORGl)

The term lateral orbital gyrus (ORGl) refers to a convolution identified by dissection on the ventral aspect of the frontal lobe (FLB) in the human and the macaque. In the human, it is partially separated laterally from the orbital part of the inferior frontal gyrus (IFGor) by an unnamed sulcus ( Mai-1997 ) and medially from the intermediate orbital gyrus (ORGim) by the lateral orbital sulcus (los). Rostrally it merges with the frontomarginal gyrus (ORGfm) and caudally with the insula ( Mai-1997 ). In the macaque, and in some sources, the part that extends caudally to the insula is called the fronto-orbital gyrus ( Krieg-1975, Martin-2000, Dubach-2008 ). Equivalent features are not seen in the smooth cerebral cortex of the rat and mouse ( NeuroNames ).

Also known as: lateral orbital gyrus, Gyrus orbitalis lateralis, gyrus orbitalis longitudinalis externus, fronto-orbital gyrus, fronto-orbital gyrus (macaque)

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.
