The first grew from the demonstration in the 1950s, by Waksman and Adams, that rabbits immunised with homologous sciatic nerve and adjuvant developed an inflammatory demyelinating neuropathy. In this model, experimental allergic neuritis, the CSF characteristically shows a raised protein concentration and a paucity of cells.
