Luxol Fast Blue staining of the thoracic spinal cord of 2-day-old piglets. A — Unaffected piglet; there is regular myelination. B — Congenital tremor-affected piglets, there is an important loss of myelin from the periphery of the cord, more severe in the lateral and ventral funiculi. Notice the normal myelination in the nerve roots (internal control). Scale bars = 1 mm.
