The Rexed laminae comprise a system of ten layers of grey matter (I-X), identified in the early 1950s by Bror Rexed to label portions of the spinal cord. [1][2]
Similar to Brodmann areas, they are defined by their cellular structure rather than by their location, but the location still remains reasonably consistent.
Laminae
- I-VI:
Posterior/dorsal horn - Lamina I: marginal nucleus of spinal cord or posteromarginal nucleus
- Laminae II: substantia gelatinosa of Rolando
- Laminae III/IV: nucleus proprius
- VII-IX:
Anterior/ventral horn - Lamina VII: intermediolateral nucleus, nucleus dorsalis
- Lamina VIII: motor interneurons
- Lamina IX: motor neurons which also contain the Onuf's nucleus in the sacral region
- Lamina X: neurons bordering
Central canal
