![]() ![]() We review the anatomy of the sulci and gyri of the cerebrum and divide it into seven lobes: frontal, central (precentral, postcentral, and paracentral gyri), parietal, occipital, temporal, insular, and limbic.Įloquent cortical areas are areas of the cortex that if removed may result in loss of linguistic ability, motor function, or sensory perception. However, knowledge of the anatomy of the sulci and gyri of the brain is helpful in planning stimulation, tumor resection, understanding tumor extensions, and correlating the findings of the magnetic resonance imaging with the operative field. The localization of function in certain anatomical cortical regions, such as Broca area, is variable among individuals and the surgeon depends upon cortical stimulation and cortical mapping to correlate function and anatomy with certainty. These areas commonly include the precentral gyrus (primary motor cortex), postcentral gyrus (primary sensory cortex), supplementary motor area (speech and motor function), the perisylvian area (language), medial occipital lobe (primary visual cortex), and medial temporal lobe (memory). Eloquent cortical areas are areas of the cortex that if removed may result in loss of linguistic ability, motor function, or sensory perception. We review the anatomy of eloquent cortical brain regions. 2 Anatomy of Eloquent Cortical Brain Regions Antonio Cesar de Melo Mussi and Evandro de Oliveira ![]()
