The functional role of Bötzinger complex (Böt. c.) projections to the expiration-related (ER) area of the caudal ventral respiratory group (cVRG) was investigated in anesthetized, vagotomized, paralyzed and artificially ventilated cats. ER neurons in both the ipsi- and the contralateral cVRG displayed excitatory responses to Böt. c. electrical microstimulation. They were also activated by microinjections of D,L-homocysteic acid into the Böt. c. region. We propose that at least part of the Böt. c. projections to the cVRG have an excitatory function.
在麻醉、迷走神经切断、麻痹并进行人工通气的猫身上，研究了包钦格复合体（Böt.c.）向尾侧腹侧呼吸组（cVRG）的呼气相关（ER）区域投射的功能作用。同侧和对侧cVRG中的ER神经元对Böt.c.的微电刺激均表现出兴奋反应。向Böt.c.区域微量注射D，L-高半胱氨酸也可激活它们。我们认为，至少部分Böt.c.向cVRG的投射具有兴奋功能。
