Dr. Kennedy The cerebral cortex is a thin mantle of gray matter covering the surface of each cerebral hemisphere of the brain. The cerebral cortex is crumpled and folded, forming numerous convolutions (gyri) and crevices (sulci). It is made up of six layers of nerve cells and the nerve pathways that connect them. The cerebral cortex is responsible for thought, perception and memory and serves as the seat of social abilities, language, motor function, and problem solving. The cerebral hemispheres are the two halves of the cerebrum. The cerebral fornices are arching fibrous bands in the brain connecting the two lobes of the cerebrum. Each fornix - there are two fornices - is a tract of nerves. The cerebral ventricular system consists of four communicating cavities within the brain continuous with the central canal of the spinal cord. The four ventricles consist of the two lateral ventricles, the third ventricle and fourth ventricles which are in the midline and unpaired. The flow of cerebrospinal fluid begins in the choroid plexus of the lateral ventricles, passes through the third and fourth venticicles and then into the spinal cord.

Accumulation of excess fluid in the substance of the brain in known as cerebral edema. The brain is susceptible to injury from edema, because it is located within a confined space and cannot expand. Cerebral herniation is protrusion of brain tissue through an opening when there is increased intracranial pressure. Increased pressure may be due to a number of causes including inflammation of the brain (as in meningitis), a tumor, hemorrhage, and edema (swelling of the brain from a metabolic imbalance). This can be fatal.
