The cerebral cortex, also known as the cerebral mantle, [1] is the outer layer of neural tissue of the cerebrum of the brain in humans and other mammals. It is the largest site of neural integration in the central nervous system , [ 2 ] and plays a key role in attention , perception , awareness , thought , memory , language , and consciousness .
The outer part of the cerebrum is the cerebral cortex, made up of grey matter arranged in layers. It is 2 to 4 millimetres (0.079 to 0.157 in) thick, and deeply folded to give a convoluted appearance. [21] Beneath the cortex is the cerebral white matter. The largest part of the cerebral cortex is the neocortex, which has
Topography of the primary motor cortex, showing which zone controls each body part. Many of the brain areas defined by Brodmann have their own complex internal structures. In a number of cases, brain areas are organized into topographic maps, where adjoining bits of the cortex correspond to adjoining parts of the body, or of some more abstract ...
The cingulate cortex is a part of the brain situated in the medial aspect of the cerebral cortex. The cingulate cortex includes the entire cingulate gyrus, which lies immediately above the corpus callosum, and the continuation of this in the cingulate sulcus. The cingulate cortex is usually considered part of the limbic lobe.
The mammalian cerebral cortex, the grey matter encapsulating the white matter, is composed of layers. The human cortex is between 2 and 3 mm thick. [11] The number of layers is the same in most mammals, but varies throughout the cortex. 6 layers can be recognized in the neocortex, although many regions lack one or more layers.
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]
Brodmann area 11, or BA11, is part of the frontal cortex in the human brain. BA11 is the part of the orbitofrontal cortex that covers the medial portion of the ventral surface of the frontal lobe. Prefrontal area 11 of Brodmann-1909 is a subdivision of the frontal lobe in the human defined on the basis of cytoarchitecture. Defined and ...
The association areas of the human brain are highly developed, and are thought to play an integral role in complex functions. [3] The association areas can be divided into 3 categories: the parasensory association cortex, the frontal association cortex, and the paralimbic association cortex. [3]
