Anatomy of the Human Brain

The Cerebrum is the largest part of the brain.  Divided into two hemispheres, the outermost layer, the cerebral cortex, has four lobes:

• Occipital used for processing visual information
  
  
• Temporal, one close to each ear, used for auditory processing, but may also be involved in emotion, learning and pronunciation/ learning a new language.
  
  
• Frontal used for solutions to complex tasks, voluntary movements, forming complete sentences when talking and personality traits
  
  
• Parietal for general sensation and feeling

The Cerebellum is located behind the top part of the brain stem where the spinal cord meets the brain and is made up of two hemispheres.  It receives information from the sensory systems, spinal cord and other parts of the brain and then regulates motor movement.  The cerebellum coordinates voluntary movement such as balance, coordination, posture, and speech, resulting in smooth and balanced muscular activity.

The Brainstem lies underneath and behind the cerebellum.  It controls the flow of messages between the brain and the rest of the body.  The brainstem also controls basic bodily functions such as breathing, swallowing, heart rate, blood pressure, consciousness, and state of sleepiness.
