Roles of each area of the brain

Each part of your brain has a different role:

The front of the brain is the center for emotions, intelligence, and reasoning. This is where much of your personality comes from. Memory is mainly stored in both temporal lobes.
The right side of your brain controls the muscles and sensation on the left side of your body. The right side also directs problem-solving and spatial skills, such as judging distance and recognizing faces. It handles many artistic and imaginative activities.
The left side of your brain controls the muscles and sensation on the right side of your body. It also handles most verbal or language skills.
The brain stem handles basic body functions, such as breathing, blood flow, and swallowing. It also controls the movement and senses of your eyes, face, and head and neck muscles. This includes swallowing, taste, and hearing.
The back of your brain (occipital lobes) controls vision.
The cerebellum is the part of your brain just below your visual cortex. It controls coordination and helps with balance and movement.
