Electrical stimulation of the corticospinal tract increases the excitability of the phrenic motoneurons directly. As a result the responses of these motoneurons to the impulses from the respiratory centre are facilitated. Until now there were attempts to explain exercise hyperpnea by increasing the activity of the respiratory centre. The experiments permit to suppose that the hyperpnea may be produced by facilitatory action of the corticospinal tract on the respiratory motoneurons, i.e. independently from the respiratory centre.
对皮质脊髓束进行电刺激可直接增加膈运动神经元的兴奋性。结果，这些运动神经元对来自呼吸中枢的冲动的反应得到促进。到目前为止，人们一直试图通过增加呼吸中枢的活动来解释运动性呼吸增强。这些实验使人们可以推测，呼吸增强可能是由皮质脊髓束对呼吸运动神经元的易化作用产生的，即独立于呼吸中枢。
