As expected, thresholds by fiber population decreased from large myelinated nerve fibers to small myelinated nerve fibers and more so for small unmyelinated nerve fibers.
These findings agree with neuropathology of a biopsy of human lead neuropathy that found loss of the large myelinated nerve fibers in a sensory nerve (Buchthal and Behse 1979).
Conversely, the nerve biopsy disclosed a severe depopulation of myelinated nerve fibers
, segmental demyelination on teased nerve preparation, and several degenerated axons.
