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.
由于已知后肢神经刺激诱发的体感诱发电位（SEP）在脊髓中双侧上行，因此研究了同时双侧刺激是否会促进或抑制刺激。在一项使用36只成年比格犬的实验中，研究了同时双侧刺激和单侧刺激在潜伏期和波幅方面的差异。未发现显著差异。然而，双侧刺激检测远场电位并不有效，在这种情况下，单侧刺激未记录到远场电位。因此证实，同时双侧刺激不会在中继通路中产生促进或抑制作用，也不会影响潜伏期。
