- The motor cortex comprises three different areas of the frontal lobe, immediately anterior to the central sulcus. These areas are the primary motor cortex (Brodmann’s area 4), the premotor cortex, and the supplementary motor area (Figure 3.1).Electrical stimulation of these areas elicits movements of particular body parts.The primary motor cortex, or M1, is located on the precentral gyrus and on the anterior paracentral lobule on the medial surface of the brain.lectrical stimulation of these areas elicits movements of particular body parts.

Cell cortex The cell cortex is attached to the inner (cytosolic) face of the plasma membrane in cells where the spectrin proteins and actin microfilaments form a mesh-like structure much like a fishnet except that it can be broken and reformed. In plant cells, the cell cortex is reinforced by cortical microtubules underlying the plasma membrane. The direction of these cortical microtubules determines which way the cell elongates when it grows. Functions. In mitosis, F-actin and myosin II form a highly contractile and uniform cortex to drive mitotic cell rounding.

Cerebral cortex The cerebral cortex is gray matter, consisting mainly of cell bodies (with astrocytes being the most abundant cell type in the cortex as well as the human brain as a whole) and capillaries.It contrasts with the underlying white matter, consisting mainly of the white myelinated sheaths of neuronal axons.he cerebral cortex plays a key role in memory, attention, perception, awareness, thought, language, and consciousness. The human cerebral cortex is 2 to 4 millimetres (0.079 to 0.157 in) thick. In large mammals, the cerebral cortex is folded, giving a much greater surface area in the confined volume of the skull.

Corpus callosum Corpus callosum. On either side of the corpus callosum, the fibers radiate in the white matter and pass to the various parts of the cerebral cortex; those curving forward from the genu into the frontal lobe constitute the forceps anterior, and those curving backward into the occipital lobe, the forceps posterior.he corpus callosum (/ˈkɔrpəs kəˈloʊsəm/ ; Latin for tough body), also known as the callosal commissure, is a wide, flat bundle of neural fibers about 10 cm long beneath the cortex in the eutherian brain at the longitudinal fissure.

The Four Cerebral Cortex Lobes of the Brain Most of the actual information processing in the brain takes place in the cerebral cortex. The cerebral cortex is divided into lobes that each have a specific function. For example, there are specific areas involved in vision, hearing, touch, movement, and smell.Other areas are critical for thinking and reasoning.he cortex (thin layer of tissue) is gray because nerves in this area lack the insulation that makes most other parts of the brain appear to be white.

- Cerebral Cortex. The cerebral cortex is the outer surface of the cerebral hemispheres. It is the highest level of the brain and has about 20 billion neurons in the human brain which carry out the highest levels of mental functioning. The cerebral cortex is a layer of grey matter up to about 1/2 cm thick. Figure 3-2d shows a cross section of the cerebral hemispheres with the cortex shown as the pink layer on their outer surface. Figure 4-2d shows a highly magnified slice through the cortex. It is stained with a dye that colors (only) the cell bodies of neurons and glia blue.

Cerebral cortex For the scientific journal, see Cerebral Cortex (journal). The cerebral cortex is the outer layer of neural tissue of the cerebrum of the brain, in humans and other mammals. It is separated into two cortices, by the longitudinal fissure that divides the cerebrum into the left and right cerebral hemispheres. The two hemispheres are joined beneath the cortex by the corpus callosum.
