  1. Lateral spinothalamic damage Area 1,2,3
    • Left entire body
    • Specific/ less specific pain and temp
  2. Lateral spinothalamic tract starts at
    S5
  3. Lateral spinothalamic tract where 1st order meets 2nd
    Laminae I-IV
  4. What can you perceive on a thalamic level
    specific and less specific touch, Pressure, pain, temp, vibration and auditory input
  5. BML nuclei
    • receives incoming info and relay to area 1 2 and3
    • intralaminar nuclei –perceive this info
  6. Ventral/ Anterior spinothalamic tract modality
    Less specific touch and pressure
  7. Ventral/ Anterior spinothalamic tract receptors
    Free nerve endings and hair end organs
  8. Ventral/ Anterior spinothalamic tract pathways
    • Primary neuron: receptor --> DRG --> DH and synapses in laminae I-IV, substancia gelatinosa
    • Secondary: crosses to contralateral side in the ventral white commissure --> lateral portion ventral funiculus --> forms bundle and ascends as lateral spinothalamic tract through lateral luminesces and synapses in thalamus (VPL)
    • Tertiary: ascends through internal capsule to post central gyrus of cerebral cortex (Areas 1,2,3 then 5 and 7) for interpretation
  9. Ventral spinothalamic tract damage left L3
    • Left LE
    • less specific touch and pressure
  10. Ventral spinothalamic damage T7
    • Left lower trunk, LE
    • less specific touch and pressure
  11. Ventral spinothalamic damage T1
    • Left trunk, LE
    • less specific touch and pressure
  12. Ventral spinothalamic damage C1
    • Left entire body
    • less specific touch and pressure
  13. Ventral spinothalamic damage VPL
    • Left entire body
    • less specific touch and pressure
  14. Ventral spinothalamic damage Area 1,2,3
    • Left entire body
    • less specific touch and pressure
