straight gyrus - BrainInfo

straight gyrus (SRG)

The term straight gyrus refers to a convolution identified by dissection at the ventromedial margin of the frontal lobe. In the human it is located between the inferior rostral gyrus on the medial surface of the lobe and the medial orbital gyrus on the ventral surface. Its boundary on the medial surface is defined by the rostral sulcus and its boundary on the ventral surface by the olfactory sulcus. It extends from the frontal pole to the level of the anterior olfactory nucleus ( Mai-1997 ). In the macaque its medial and ventral boundaries are the same as in the human, and it extends from the frontal pole to the level of the olfactory tubercle ( Martin-2000 ). Equivalent structures are not seen in the smooth cerebral cortex of the rat and mouse ( NeuroNames ).

Also known as: gyrus rectus, Gyrus rectus, straight gyrus, rectus gyrus, rectal gyrus, medial part of gyri orbitales, ventromedial gyrus

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.
