The cerebral hemispheres physically dominate the structure of the brain. Many functional areas of the brain gyri have been identified. Four pairs of lobes are present in the cerebrum and various functions have been associated with these lobes. Temporal lobes receive and process auditory information. Association areas of the temporal lobes are involved in recognition, identification, and naming of objects.
Occipital lobes receive and process visual information.
Parietal lobes are separated from the frontal lobes by the central sulcus . The part of each parietal lobe immediately behind the central sulcus is the primary somatosensory cortex . This area receives information through the thalamus about touch and pressure sensations. The thumb and hand send a great deal of information to this part of the cortex illustrating their importance. The frontal lobes are also involved in personality planning viewing oneself in context with the surrounding world.
