Overview

A gyrus (pl. gyri) is a ridge on the cerebral cortex. It is generally surrounded by one or more sulci.

Notable gyri

• Fornicate gyrus
• Superior frontal gyrus, lat. gyrus frontalis superior
• Middle frontal gyrus, lat. gyrus frontalis medius
• Inferior frontal gyrus, lat. gyrus frontalis inferior with 3 parts:

• pars opercularis
• pars triangularis
• pars orbitalis

• Superior temporal gyrus, lat. gyrus temporalis superior
• Middle temporal gyrus, lat. gyrus temporalis medius
• Inferior temporal gyrus, lat. gyrus temporalis inferior
• Fusiform gyrus, lat. gyrus occipitotemporalis medius
• Parahippocampal gyrus, lat. gyrus parahippocampalis
• Transverse temporal gyrus
• Precentral gyrus, lat. gyrus praecentralis
• Postcentral gyrus, lat. gyrus postcentralis
• Supramarginal gyrus, lat. gyrus supramarginalis
• Angular gyrus, lat. gyrus angularis
• Cingulate gyrus lat. gyrus cinguli
• Dentate gyrus lat. gyrus dentatus
• Cuneus
• Lingula lat. gyrus lingualis
