We used single-unit vagal recordings to study the average discharge pattern during a respiratory cycle from 57 intrapulmonary CO2 receptors in 6 ducks artificially ventilated with a Starling pump. Peak discharge frequency occurred during inspiration in 51%, expiration in 19%, and both inspiration and expiration in 30% of the receptors. Average discharge frequency from all receptors was maximum at mid-inspiration, but frequency also increased slightly during early expiration. The results suggest that the brain receives a discharge pattern from the total population of intrapulmonary CO2 receptors which is phasic with respiration. Such a signal may control the rate and amplitude of breathing.
我们使用单单位迷走神经记录法，研究了用斯塔林泵进行人工通气的6只鸭的57个肺内二氧化碳受体在一个呼吸周期中的平均放电模式。51%的受体在吸气时出现放电频率峰值，19%在呼气时出现，30%在吸气和呼气时均出现。所有受体的平均放电频率在吸气中期最高，但在呼气早期频率也略有增加。结果表明，大脑接收到来自肺内二氧化碳受体总体的与呼吸同步的放电模式。这样一个信号可能控制呼吸的速率和幅度。
