Rexed laminae
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: posteromarginal nucleus
- Laminae II/III: substantia gelatinosa
- Laminae III/IV/V: nucleus proprius
- Lamina VI: nucleus dorsalis
- VII-IX: Anterior/ventral horn
- Lamina VII: intermediolateral nucleus
- Lamina VIII: motor interneurons
- Lamina IX: motor neurons which also contain the nucleus of onuf in the sacral region
- Lamina X: neurons bordering Central canal
