Electrical stimulation of 80% of negative and 82% of positive sites of the rabbit hypothalamus increased the latent period of thermal nociceptive stimulus avoidance and diminished the evoked potential amplitude in the parafascicular complex of the thalamus in response to electrical nociceptive stimulation of the skin. The opposite effects were evoked by subthreshold stimulation of the negative rather than positive sites. Electrical stimulation of neutral sites had not effect on the test parameters of pain sensitivity.
对家兔下丘脑80%的负极位点和82%的正极位点进行电刺激，可延长热痛觉刺激回避的潜伏期，并降低丘脑束旁复合体在皮肤受到电伤害性刺激时诱发的电位幅度。阈下刺激负极位点而非正极位点会产生相反的效果。对中性位点进行电刺激对痛觉敏感性的测试参数没有影响。
