The cerebral cortex is the outermost layered structure of the brain and controls higher brain functions such as information processing.
Label a diagram illustrating parts of the cerebral cortex.
Define the cerebral cortex and explain its role related to the cerebrum in mammals.
The cerebral cortex, the largest part of the brain, consists of a thin layer of grey matter that covers the cerebral hemispheres. It is the ultimate control and information-processing center in the brain.
While the cortex is less than 1/4" thick, it is responsible for many "higher-order brain functions such as sensation, perception, memory, association, thought, and voluntary physical action.
The cerebrum is the large, main part of the brain and serves as the thought and control center.
The cerebral cortex, the largest part of the mammalian brain, is the wrinkly, grey outer covering of the cerebrum. While the cortex is less than 1/4" thick, it is here that all sensation, perception, memory, association, thought, and voluntary physical actions occur. The cerebral cortex is considered the ultimate control and information-processing center in the brain.
The cortex is made of layers of neurons with many inputs; these cortical neurons function like mini microprocessors or logic gates. It contains glial cells which guide neural connections, provide nutrients and myelin to neurons, and absorb extra ions and neurotransmitters. The cortex is divided into four different lobes - the parietal, occipital, temporal, and frontal lobes - which will be discussed in detail in the following section.
Parts of the Cerebral Cortex
Diagram of the brain identifying the different lobes by color. It contains the parietal lobes (green), the occipital lobes (yellow), the temporal lobes (orange), and the frontal lobes (red).
Beneath the cerebral cortex, the inside of the cerebrum beneath is comprised of white matter made up of myelinated neurons that carry information from one part of the brain to another. The cerebrum is the large, main part of the brain, which serves as the main thought and control center. It is the seat of 'higher level' thought, like emotions and decision making, as opposed to 'lower level' thought, like balance, movement, and reflexes.
The cerebrum is divided by the longitudinal fissure into a right hemisphere and a left hemisphere. These hemispheres each have their own unique 'persona'. People who are described as being more 'right brained' are often more intuitive; whereas people who are more 'left brained' are often more logical. Each cerebral hemisphere perceives and controls the opposite side of the body.
The cerebral cortex is covered by the cerebrum., The cerebrum and cerebral cortex together make up the frontal lobe., The cerebral cortex is located above, and dictates the activity of, the cerebrum., and The cerebrum is covered by the cerebral cortex.
