(7) A subpopulation of identified postsynaptic dorsal column neurons also showed a significant increase in the percentage that responded to sural nerve stimulation after DLF lesions.
(8) Muscle biopsies revealed neurogenic atrophy and sural nerve biopsies were histologically unremarkable.
(9) We have studied the physiology of primary sensory neurons innervating rat hindlimb muscle in the following: 1) normal control animals; 2) animals in which the gastrocnemius nerve (Gn) had regenerated to its original muscle target; and 3) animals in which the cutaneous sural nerve (Sn) had regenerated to a foreign target, muscle.
(10) In 167 consecutive patients with various types of neuropathy, the amplitude of the sensory potential and the maximum conduction velocity along the sural nerve were compared with conduction in other sensory nerves, and were related to structural changes revealed by nerve biopsy.
