[Peripheral and central neural conduction in the rat].

The orthodromic sensory nerve conduction velocity was measured on the tail nerve of 35 male and 14 female Wistar rats. The spinal somatosensory evoked potential also was determined for the excitation of the tail and lower limb over the 5th and 1st lumbar vertebrae. The cervical response and cortical somatosensory evoked potential were determined for the stimuli of the hind and fore paw. Normal values are compared with the latencies evaluated by upper limb stimulus. Differences between both sexes are discussed.
