title: Central core in the spinal grey matter.
abstract: Golgi--Kopsch impregnated spinal cord sections of adult cats revealed a regular orientation of the dendrites in the intermediate region forming a circular or elliptical grey matter. The orientation of the dendrites is strictly transverse in the central core. A new interpretation of the spinal grey matter is proposed by viewing the dorsal, lateral and ventral horns (or columns) as crest-like appendages attached to the rod-like central core. A structural and possibly functional similarity between the central core and the brain stem reticular formation is emphasized.
