Ever since there were doctors performing experiments, there has been a fascination with the brain of all the earth’s species. The most complicated of those being the human brain. The human brain is made up of several structures that perform everyday functions. The outer part, or the cerebral cortex, divides its functions into parts. The areas, located in the cerebral cortex, are divided by the longitudinal fissure into two cerebral hemispheres, which runs through the middle of the brain. The left hemisphere controls the right half of the body and controls speech, while the right half controls the left half of the body and governs spatial perceptions. The brain is then divided into four lobes by the central sulcus and the lateral sulcus. These lobes deal with sight, hearing, movement, speech, and other mental activities, each performing there own specific functions. The frontal lobe, the largest lobe in the human brain, is located before the central sulcus, or anterior end of the cerebrum, and extends to the anterior boundary of the cerebral cortex. It consists of an anterior pole called the prefrontal cortex, which receives sensory information, and is responsible for thinking, problem solving, motor movement, impulse control and programming individual needs and emotion.
