Gyrus rectus

Dr Craig Hacking and Dr Julian Maingard et al.

The gyrus rectus, or straight gyrus, is located at the medial most margin of the inferior surface of frontal lobe 1,2. Its function is unclear but it may be involved in higher cognitive function (e.g. personality) 3.

The gyrus rectus is bounded medially by the interhemispheric fissure and wraps around to the inferomedial surface of the frontal lobe, where it is separated from the rostral gyrus by the inferior rostral sulcus 5.

Inferolaterally it is separated from the medial orbital gyrus by the olfactory sulcus.

Anteriorly, gyrus rectus is continuous with the superior frontal gyrus (or more precisely the inferior frontopolar gyrus of the frontal pole1,2,4.
