title: Effect of simultaneous bilateral tibial nerve stimulation on somatosensory evoked potentials (SEP) in dogs.
abstract: Since somatosensory evoked potentials (SEP) by hindlimb nerve stimulation are known to ascend bilaterally in the spinal cord, it was investigated whether or not simultaneous bilateral stimulation causes facilitation or inhibition of the stimuli. In an experiment using 36 adult Beagle dogs, the difference between simultaneous bilateral stimulation and unilateral stimulation was studied as to latencies and amplitudes. No significant difference was noted. However, the detection of far-field potentials by bilateral stimulation was not effective in which case far-field potentials did not recorded by unilateral stimulation. It was therefore confirmed that simultaneous bilateral stimulation does not cause facilitation or inhibition in the relay pathways, and does not affect the latency.
