The marginal nucleus of spinal cord or posteromarginal nucleus or Substantia Marginalis Rexed lamina I is located at the most dorsal aspect of the dorsal horn of the spinal cord. The neurons located here receive input primarily from Lissauer’s tract and relay information related to pain and temperature sensation. Pain sensation relayed here cannot be modulated e.g. pain from burning the skin.
