The displace- ment group demonstrated more severe edema of the DRG, and the combination group demonstrated edema, endothelial and Schwann cell hypertrophy, demyelinization, and widespread myelin abnormali- ties at postprocedure day 21.

other cranial nerves (V, VII, IX, and XI), which also originate in the brainstem. The ventral vagus is myelinated, i.e., insulated by a covering of Schwann cells (connective-tissue cells) that enable it to transmit information more rapidly than non-myelinated nerves. The dorsal vagus, the older of the
