Basically the brain can be divided into three different regions: hindbrain, midbrain and forebrain. Each of these regions is in turn divided into separate areas responsible for quite distinct functions, all intricately linked to other parts of the brain.
The largest structure in the hindbrain is the cerebellum. The largest part of the entire brain is the cerebrum, which is located in the forebrain. It is more developed in humans than in any other animal. This is where the other parts of the brain send incoming messages for decision. The cerebral cortex is the thick wrinkled layer of grey matter folded over the outside of the cerebrum. This part of the brain has become so highly developed in humans that it has had to fold over and over in order to fit inside the skull. Unfolded, it would cover an area 30 times as large as when folded.
The brain is the body’s control center. It keeps the body working smoothly and it looks after thoughts, feelings and memory.
Different parts of the brain have different functions to perform. The largest part is called the cerebrum, or forebrain. It looks like a huge half-walnut. The cerebrum’s main job is to sort out and respond to messages sent to it from the sense. It also stores information, as memory, and it thinks.
Messages from the senses are managed by the cerebrum’s sensory area, while the motor area controls the muscles. Thinking, memory and speech are managed by the parts known as the association area. The cerebellum (hindbrain) is below the cerebrum. It works with the cerebrum’s motor area to ensure that the muscles function smoothly.
