The cerebrum is the upper and larger portion of the brain and occupies the whole of the dome of the skull. The cerebrum is descriptively divided into four section, or lobes, named for the cranial bones which they are nearest: the frontal lobe, the occipital lobe, the parietal lobe, and the temporal lobe. Cerebrospinal fluid, used to support the brain and buffer it, is transmitted to these lobes by means of lateral ventricles which project branches, or horns (cornu), into the frontal, occipital, and temporal lobes. The functions of each lobe are coordinated by connecting, or commissural, fibres. The frontal lobe is located behind the frontal bone and is responsible for voluntary motor coordination. It houses control areas for muscular control of the body and for coordinated rhythmical movements of the head and throat, such as in chewing, licking, and swallowing. The frontal lobe also contains the higher thought processing centers of memory, reasoning, and associative conceptualizing.
The occipital lobe is located just in front of the occipital bone and contains the centers responsible for sight. Damage to the occipital lobe therefore often results in vision impairment. The parietal lobe is located in the upper, middle part of the brain, next to the parietal bones. It houses the control centers for processing impulses related to the sense of touch. Temperature, texture, size, shape, and weight are analyzed and processed here. The temporal lobe is located on the side of each hemisphere of the brain, next to the temporal bone, and houses areas for the processing and correlation of auditory (hearing) and olfactory (smell) senses. Damage to this section of the brain can result in deafness, auditory hallucinations, and other hearing disorders. Research Cerebrum
