Brain: supratentorial cortical anatomy.

Knowledge of the cerebral cortical lobes and gyri is critical for the localization of lesions and for the correlation of radiologic findings with neurologic symptoms and signs. This article deals with the six cerebral lobes-frontal, parietal, occipital, temporal, limbic, and insula-and the fissures and imaginary lines that divide them. The major gyri and sulci of each lobe are individually considered. Anatomy and function are correlated for a few selected areas of particular clinical importance.
