Gyri of the Main Lobes of the Brain, Lateral View

Description

Presented in lateral aspect, the cerebral hemisphere is organized into color-coded frontal, parietal, temporal, and occipital lobes, separated by the central sulcus and the lateral sulcus (Sylvian fissure). Along the anterior to posterior convexity, the precentral gyrus lies immediately anterior to the central sulcus and the postcentral gyrus immediately posterior, while the superior, middle, and inferior frontal gyri run parallel on the lateral frontal surface. Inferior to the lateral sulcus, the superior and middle temporal gyri are visible with the inferior temporal gyrus continuing toward the occipital pole, and the cerebellar hemisphere sits posteroinferior to the occipital lobe with the brainstem descending inferiorly. A lateral view like this is the workhorse orientation for correlating surface anatomy with neurologic deficits, because motor and somatosensory cortices occupy opposing banks of the central sulcus and map clinically to contralateral face and upper limb function along the lateral convexity. Language-dominant hemisphere localization also starts here: Broca area is typically placed in the posterior inferior frontal gyrus, and Wernicke area along the posterior superior temporal gyrus near the lateral sulcus, a practical framework when teaching aphasia patterns or planning an awake craniotomy. Lesions of the occipital lobe at the posterior pole, by contrast, steer you toward cortical visual field loss. Neurology and neuroanatomy courses use this plate to anchor gyrus and lobe nomenclature before introducing functional maps, vascular territories, and cross-sectional imaging correlation. It also fits cleanly into patient-facing education and neurosurgical consent materials when explaining stroke syndromes, tumor location, or operative corridors that respect the central sulcus and peri-Sylvian cortex.
