Cell part cluster consisting predominantly of neurites in the brain and the spinal cord[FMA:83929]., Multi-tissue structure comprised largely of myelinated axons.[TAO]

nlx_anat_101177 seems to have been lost in the transition from NIFGA to Neurolex

has related synonym

substantia alba, CNS tracts and commissures, CNS white matter, white mater

homology notes

The myelination of axons by glial cells was the last major step in the evolution of cells in the vertebrate nervous system, and white-matter tracts are key to the architecture of the mammalian brain.[well established][VHOG]
