In vivo intracellular recording and intrasomal injection of Lucifer yellow revealed two populations of postganglionic parasympathetic neurons in the tracheal ganglia of cats. One consisted of large cells that had an inspiratory rhythm, had a significant post-spike afterhyperpolarization, and projected to the tracheal smooth muscle. The second consisted of small cells that fired with an expiratory rhythm, had no significant afterhyperpolarization, and projected to the intercartilaginous spaces.
在体细胞内记录和向胞体内注射路西弗黄显示，猫气管神经节中有两类节后副交感神经元。一类由大细胞组成，具有吸气节律，锋电位后有明显的超极化后电位，并投射至气管平滑肌。另一类由小细胞组成，以呼气节律放电，无明显的超极化后电位，并投射至软骨间隙。
