摘要：
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. © 1990.
