Component items:

Lamina I (LPC.SC.PH.L1)
- Marginal Nucleus (LPC.SC.PH.MG): Relay information related to pain and temperature sensation
  - Upper Marginal Nucleus: Relay information related to pain and temperature sensation - C1-C8,T1-T6
  - Lower Marginal Nucleus: Relay information related to pain and temperature sensation - T7-T12,L1-L5,S1-S5,CX
Lamina II (LPC.SC.PH.L2)
- Substantia Gelatinosa (LPC.SC.PH.SG): Relay for C-fibers of slowly conducting, poorly localized pain sensation
  - Upper Substantia Gelatinosa: Relay for C-fibers of slowly conducting, poorly localized pain sensation - C1-C8,T1-T6
  - Lower Substantia Gelatinosa: Relay for C-fibers of slowly conducting, poorly localized pain sensation - T7-T12,L1-L5,S1-S5,CX
Lamina III, IV (BMA.SC.PH.L34)
- Proprius Nucleus: Relay light touch, pain and temperature information
Lamina V, VI (BMA.SC.PH.L56)
- Clarke Nucleus: Unconscious Proprioception
