A
  1. Spinal lemnisucs - Contralateral Hemianalgesia
  2. Medial Lemniscus - Contralateral Proprio/2pt
  3. Trigeminal lemniscus
  4. Lateral lemniscus - Bilateral Diminished hearing with the contralateral side having more hearing loss than the other
  5. Descending tract of V - Hemianalgesia to the face
  6. Corticospinal Tract - Contralateral Spastic Hemiplesia
  7. Corticobulbar Tract - Supernuclear Facial Palsey (crosses over @ the Pons between CN V and VI)
