- - - - Cerebral peduncles
    - - Pyramidal tracts: Go
    - - Reticular Formation Nuclei: Controls autonomic behaviors
  - - - Parietal
        
        Postcentral Gyrus
        
        Primary somatosensory cortex
        
        Wernickes area: understanding speech
      - Temporal: Limbic system, visual/auditory cortex, recognition, memory
      - Frontal
        
        Precentral Gyrus
        
        Primary Motor Cortex: Voluntary movement
        
        Prefrontal cortex: Task management, decisions, memory, problem solving
        
        Broca's area: prdouces speech
      - Occipital: Visual cortex
    - - Commissural tracts: Connects the two hemispheres
      - Projection tracts
        
        Descending tracts: Carry motor signals
        
        Ascending tracts: Carry sensory info
      - Association tracts: Connects same hemisphere
  - - - Pinal Gland: Makes us sleepy
  - - - Tight Junctions: Limit leaking and help keep invaders out
- - - - Carries motor signals
    - - Posterior Root Ganglion: Cluster of satelite and sensory neuron cell bodies
      - Carries sensory signals
