  2. Brodmann area 40 - Wikipedia

    en.wikipedia.org/wiki/Brodmann_area_40

    Brodmann area 40 (BA40) is part of the parietal cortex in the human brain. The inferior part of BA40 is in the area of the supramarginal gyrus , which lies at the posterior end of the lateral fissure , in the inferior lateral part of the parietal lobe .

  3. Lateral surface - Wikipedia

    en.wikipedia.org/wiki/Lateral_surface

    For a cube the lateral surface area would be the area of the four sides. If the edge of the cube has length a, the area of one square face A face = a ⋅ a = a 2. Thus the lateral surface of a cube will be the area of four faces: 4a 2. More generally, the lateral surface area of a prism is the sum of the areas of the sides of the prism. [1]

    en.wikipedia.org/wiki/Lobes_of_the_brain

    The insular cortex is divided into two parts: the larger anterior insula and the smaller posterior insula in which more than a dozen field areas have been identified. The cortical area overlying the insula toward the lateral surface of the brain is the operculum (meaning lid). The opercula are formed from parts of the enclosing frontal ...

    Frontal lobe (red) of left cerebral hemisphere. The frontal lobe is the largest lobe of the brain and makes up about a third of the surface area of each hemisphere. [3] On the lateral surface of each hemisphere, the central sulcus separates the frontal lobe from the parietal lobe. The lateral sulcus separates the frontal lobe from the temporal ...

    Gray's FIG. 726 – Lateral surface of left cerebral hemisphere, viewed from the side Gray's Fig. 727 – Medial surface of left cerebral hemisphere. In neuroanatomy, a gyrus (pl.: gyri) is a ridge on the cerebral cortex. It is generally surrounded by one or more sulci (depressions or furrows; sg.: sulcus). [1]

  9. Cerebral hemisphere - Wikipedia

    en.wikipedia.org/wiki/Cerebral_hemisphere

    Each cerebral hemisphere has an outer layer of cerebral cortex which is of grey matter and in the interior of the cerebral hemispheres is an inner layer or core of white matter known as the centrum semiovale. [3] The interior portion of the hemispheres of the cerebrum includes the lateral ventricles, the basal ganglia, and the white matter. [4]
