The activity of single motor units of the intercostal muscles has been studied during reactions of thermoregulation in cats. It has been shown that during shivering both respiratory and tonic units are functioning with a frequency of discharges of 5--12/sec. A marked increased in the quantity of active tonic motor units was revealed in shivering. During warming of the animal and cessation of shivering first the tonic units and then the respiratory ones ceased to discharge. The thermoregulatory function of the intercostal muscles seems to be achieved essentially by tonic motoneurons activated by cold stimulation.
在猫的体温调节反应过程中，对肋间肌单个运动单位的活动进行了研究。结果表明，在寒颤期间，呼吸性和紧张性运动单位均以每秒5 - 12次的放电频率发挥作用。在寒颤过程中，发现活跃的紧张性运动单位数量显著增加。在动物体温升高且寒颤停止时，先是紧张性运动单位，然后是呼吸性运动单位停止放电。肋间肌的体温调节功能似乎主要是由冷刺激激活的紧张性运动神经元实现的。
