Nucleus centrobasalis

Name: Nucleus centrobasalis
Description: Nucleus located in the cervical and lumbosacral enlargements at base of the dorsal horn, bordered dorsally by the n. proprius cornus dorsalis, and ventrally by the zona intermedia. Cells comprising this nucleus vary widely in size. Large cells appear to project ipsilaterally to the cerebellum. The nucleus is a major site of termination for dorsal root fibers. Petras and Cummings suggest that these cells give rise to the rostral spinocerebellar tract.[1]
Is part of: Cervical spinal cord dorsal horn[1]
Super-category: Regional part of spinal cord
*Id: nlx_143588

Cyto-architecture defining Criteria: The cells comprising this nucleus vary widely in size. It was best identified in Nissl stain in sections 100-200 um thick [1]
Myelo-architecture defining Criteria: Weil or Weigert preparations reveal an abundantly myelinated neuropil in the basilar region of the dorsal horn. [1]
Connectivity defining Criteria: Following dorsal rhizotomy, the centrobasilar territory was distinguished by massive numbers of degenerated fibers stained by the Nauta technique or its variants. [1]
Brain regions that send axons into this region: dorsal root ganglion
Brain regions that receive axons from this region: cerebellum
