Brain, Lateral View

Description

Left lateral encephalon anatomy comes into view with the cerebral hemisphere dominating the field, its frontal lobe positioned anteriorly, the parietal lobe superior and posterior to the central sulcus, the temporal lobe inferolateral beneath the lateral (Sylvian) sulcus, and the occipital lobe forming the posterior pole. Prominent gyri and sulci logically include the precentral and postcentral gyri straddling the central sulcus, the superior temporal gyrus paralleling the lateral sulcus, and the lateral convexity of the parietal cortex sweeping superiorly toward the intraparietal region. Along the inferior aspect, the temporal pole sits anterior to the temporal gyri, while posteriorly the occipital cortex rounds toward the calcarine territory, largely hidden on the medial surface. Surface landmarks. Matter here. A true lateral perspective matters because it matches the way clinicians localize cortical function at the bedside and in operative planning, using sulci as reliable coordinates for motor and somatosensory cortex, perisylvian language networks, and the temporal association areas. For example, mapping lesions relative to the central sulcus helps distinguish precentral gyrus involvement (contralateral weakness) from postcentral gyrus involvement (contralateral sensory loss), while perisylvian pathology on the dominant side aligns with aphasia patterns seen in middle cerebral artery stroke. This view also supports teaching the opercular region and the course of superficial cortical veins encountered during pterional or frontotemporal craniotomy. Neuroanatomy and neuroscience courses use this plate to drill gyral and sulcal identification on the lateral convexity, and to anchor functional regions before moving to coronal sections and MRI. Neurology texts, stroke education materials, and neurosurgical presentations can pair it with vascular territory diagrams to explain why MCA infarcts preferentially affect the lateral frontal, parietal, and superior temporal cortices.
