Full Answer

One of the primary structures of the supratentorial region, the cerebrum, is divided into two hemispheres. These hemispheres are split by fissures into four separate lobes, which are responsible for different tasks in the brain. The frontal lobe is responsible for logic and planning, and a small subdivision of the frontal lobe, called Brocha's area, is responsible for language development. The frontal lobe is also contains an individual's intelligence and personality.

The parietal lobes interpret physical sensations, such as temperature and pressure, and also allow humans to perform arithmetic. The temporal lobes help with understanding language and sound, as well as short-term memory. The occipital lobe contains the visual center of the brain. The right occipital lobe receives visual data from the left eye, while the left lobe interprets data from the right eye. The other structure, the diencephalon, is located in the center of the brain and contains three of the brain's most important structures – the thalamus, the hypothalamus and the pituitary gland – which handle tasks such as relaying information to other parts of the brain and controlling hormones related to sexual development, thyroid production and growth.
