What the Brain Does

Side view of brain in head with blood vessels.Each part of your brain has a different role. The brain controls your breathing, heart rate, digestion, temperature regulation, your 5 senses, and movement. The brain also allows you to think, communicate, handle emotions, and make judgments among many other critical functions. 

The Brain

Roles of different areas in the brain

Different areas of the brain have different functions: 

  • 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.

  • The back of your brain controls vision.

  • The cerebellum is the part of your brain located just below your visual cortex. It controls coordination and helps with balance and movement.
