Rabbit nasal airway receptors were investigated electrophysiologically in vitro. Cold receptors, warm receptors, and mechanoreceptors were found in the nasal membrane. The cold receptors showed a maximum static discharge at 28 degrees C, and the warm receptors at 38 degrees C. These thermoreceptors were activated constantly at temperatures between 18 degrees C and 40 degrees C. The mechanoreceptors were seen to adapt rapidly to gentle mechanical stimulation and were activated easily by repeated stimuli. Air blown directly at the nasal membrane did not activate the mechanoreceptors. It was concluded that nasal airflow sensation is due mainly to the activation of cold or warm receptors in the nasal airway, rather than the stimulation of mechanoreceptors.
对兔鼻气道受体进行了体外电生理研究。在鼻黏膜中发现了冷感受器、温感受器和机械感受器。冷感受器在28℃时表现出最大静息放电，温感受器在38℃时表现出最大静息放电。这些温度感受器在18℃至40℃之间的温度下持续被激活。机械感受器能迅速适应轻微的机械刺激，并且容易被重复刺激激活。直接吹向鼻黏膜的气流不会激活机械感受器。得出的结论是，鼻气流感觉主要是由于鼻气道中冷或温感受器的激活，而不是机械感受器的刺激。
