to evaluate the correlation between the numbers of the myelinated fibers and the patterns of white matter degeneration in spinal cords , the latter were classified into three groups : group a with selectively demarcated degeneration of lateral and anterior corticospinal tracts , group b with diffuse degeneration of antero-lateral spinal columns and group c with no degeneration of the spinal white matter .
