The brain is the central organ in the human body which manages every word uttered, movement made and idea or thought construed. Weighing approximately three pounds, the brain is small considering its size in proportion to the rest of the human body.

Yet the role it plays is an essential one in comparison with the rest of the body's organs. Other organs can be artificially produced or even removed, but technology does not have a way to duplicate the brain, its functions are primary to our very existence.

The brain is comprised of three primary areas, the brain stem, cerebellum and cerebrum. Encased inside the cerebrum are four lobes: frontal, occipital, parietal, and temporal. Situated below the lobes are the cerebellum and the brain stem.

Each of these three primary areas and their components serves specific functions, and if an injury occurs to any of these areas, it impacts our various abilities in both physical and cognitive areas.

Brain Lobes

*Frontal Lobe

Located in the front of the brain under the forehead, the frontal lobe houses a person's personality and manages their emotions. Most human behaviors are controlled by this lobe, which also takes part in motor function, problem solving, judgment calls, spontaneity, memory, language, and social and sexual behaviors.

The frontal lobe is divided into two sections, the anterior and the posterior. The anterior controls the higher level thinking, or cognitive functions, and the posterior area of the frontal lobe control movement.

People who have suffered an injury to the frontal lobe will often experience a loss of either short or long term memory, have impulsivity or experience issues with executive functioning skills. Problems with organizational thinking or problem solving often results from a frontal lobe injury.

Aphasia is another common occurrence with injury of the frontal lobe; this impacts a person's ability to express language. The frontal lobe is one of the most common lobes afflicted in a traumatic brain injury (TBI).

*Occipital Lobe

The occipital lobe is housed in the lower back of the brain. Its primary function is visual perceptions. Damage to this lobe can result in loss of vision, hallucinations, or cause other visual impairments such as the ability to see color or accurately see accurate perceptions of objects. People who suffer injuries to this lobe are likely to have visual deficits.

*Parietal Lobe

This lobe is located in the upper rear of the brain and controls sensation, perception and
