      - Plan, initiate & produce voluntary movement
    - - Process sensory stimuli
      - Consciously aware general somatic sensation; conscious of objects, sounds & body parts
    - - Primary auditory, olfactory cortex
      - Recognize objects, words, faces & language comprehension
      - Emotional response & memory
    - - Visual Cortex
    - - Primary cortex for gustation & general visceral sensation
  - - - Location of primary motor cortex (sending)
      - Pyramidal Neurons
    - - Location of primary somato sensory cortex
      - General sensory: touch, pain, vibrations
      - Skin, muscles, joint
  - - - Frontal; left hemisphere; controls motor movements of speech
    - - Speech comprehension area (temporal parietal region; left hemisphere)
      - Allows us to name viewed objects & read words
  - - - Connects parts of cortex of same hemisphere
    - - Connects one hemisphere to another; corpus callosum in the mid-saggital section
    - - Both ascending & descending
- - - - Tough, dense, fibrous connective tissue
      - 2 Layers: Periosteal layer, Meningeal layer
    - - Subarachnoid space & blood vessels filled with C.S.F
    - - Very thin and very vascular
- - - - composed of pyramids motor tracts coming from cerebral cortex
    - - Broken down into superior colliculi and inferior colliculi
