nervous system
• make fewer turns around axons and otherwise showing varying degrees of abnormal development and degeneration
• schwann cells formed little compacted myelin and that was abnormal
• at 1 year of age, conduction velocities in the sciatic nerve were reduced, temporal dispersion slowed, polyphasia, increased latencies

• after 2 weeks of age, body showed weak vibrations when lifted by the tail
• by 4 weeks of age clasping of the hindlimbs when lifted by the tail
• becoming more pronounced with age, sometimes leading to convulsions
• weak forelimbs and hindlimbs in adults
• becoming more pronounced with age
• uncoordinated
• dragging or jerky movements of hindlimbs
