Abstract: The fasciculus gracilis and fasciculus cuneatus of the spinal cord of mutant Wistar rats (Rattus norvegicus) were studied by light microscopy at the level of the first and sixth cervical segments in order to determine the extent of myelination at zero, 1, 3, 5, 10, 15, 30 and 120 days of postnatal life. The fasciculus gracilis was found to be practically nonmyelinated at birth, with effective myelination activity starting after the 5th day of age. At the 20th day of age, myelination was more than was more than 50% completed compared to adult 120-day old animals. At birth, the fasciculus cuneatus had myelin fibers and always presented a greater extent of myelination than the fasciculus gracilis at each stage assessed. At the 20th day of age, more than 3/4 of fasciculus cuneatus were myelinated comparing to adult 120-day old animals at level of the first cervical segment. Thus, the myelination of the fasciculus gracilis and fasciculus cuneatus of the spinal cord of mutant Wistar rats was processed as the normal rat, demonstrating that the mutation of
