Experiments were done on 33 adults cats. After injection of WGA-HRP (5%, 30-60 nl) into the Bötzinger complex, labelled cells were observed in the lateral parabrachial nucleus and the Kölliker-Fuse nucleus. Injection into control sites failed to label the cells in the above two nuclei. Ninety-one respiratory related neurons recorded from the pneumotaxic center were tested by electrical stimulation of the Bötzinger complex. Thirteen neurons (14.3%, inspiratory 11, phase-spanning 2) could be antidromically activated. Results of the present study showed that neurons in the pneumotaxic center sent axons to the Bötzinger complex concerning respiratory control.
对33只成年猫进行了实验。向包钦格复合体注射WGA-HRP（5%，30 - 60 nl）后，在臂旁外侧核和 Kölliker-Fuse 核中观察到标记细胞。注射到对照部位未能标记上述两个核中的细胞。通过电刺激包钦格复合体对从呼吸调整中枢记录到的91个呼吸相关神经元进行了测试。13个神经元（14.3%，吸气性11个，跨相性2个）可被逆向激活。本研究结果表明，呼吸调整中枢的神经元向参与呼吸控制的包钦格复合体发出轴突。
