      - Occipital Lobe
        
        Back portion of brain
        
        Interpreting visual stimuli and information
        
        Primary visual vortex
        
        receives and interprets information fro the retinas of eyes.
        
        Damages

        identify colours
        
        recognizing objects
        
        recognizing words
      - Parietal Lobe
        
        Middle section of brain

        Somatosensory cortex is located
        
        Essential to the processing of the body's senses
      - Temporal Lobe
        
        Bottom section of brain

        Speech perception
        
        Language skills
    - - Not a lobe, connects two halves of brain together
      - allows communication of.. b/w both sides of the brain
        
        motor
        
        sensory
        
        cognitive information
  - - - composed of small lobes
        
        receives information from
        
        the balance system of the inner ear
        
        sensory nerves
        
        auditory and visual systems
        
        involved in coordination of movements & motor learning
    - - accounts for more than 50 % of total # of neurons located in brain
        
        serves to modify signals and make motor movements accurate and useful
    - - posture
      - balance
      - coordination of voluntary movements
  - - - responsible for controlling...
        
        hunger, thirst, emotions, body temp regulation, circadian rhythms
        
        also pituitary gland by secreting hormones
  - - - Processes and transmits movement and sensory information
        
        'relay station'
        
        take sensory information and pass it on the cerebral cortex
        
        cerebral cortex also sends information to the thalamus
