median fissureSee the matched myelin stained section in Plates 104A and B
Note the uniform light staining of the white matter in this and all other cell body stained sections in this specimen. That indicates
that myelination gliosis is completely fi nished, even in the lateral corticospinal tract, because nearly all tracts are either myelin-
ated or myelinating. Refer to the matching myelin stained section for the approximate locations of both corticospinal tracts, the
medial longitudinal fasciculus, the tectospinal, lateral reticulospinal, vestibulospinal, intraspinal, and spinocephalic tracts.PLATE105B
