According to Souza, numbness caused by which site presents bilaterally and may involve the central cord?

Numbness that is bilateral and may involve the central cord points to a lesion in the central nervous system. Peripheral nerves, nerve roots, and nerve plexuses typically produce unilateral, segmental patterns that follow specific nerves or dermatomes. In contrast, involvement of the CNS can affect sensory pathways on both sides and may involve central spinal cord areas, leading to bilateral sensory changes. So the bilateral distribution with potential central cord involvement makes CNS the best site to localize the numbness.
