1. The effects of ionophoretic application of acetylcholine (ACh) and cholinergic antagonists to respiratory neurones of the nucleus ambiguus-retroambigualis complex were studied in cats. 2. Acetylcholine was ineffective when applied to inspiratory neurones (27/31) but inhibited the spontaneous activity of a significant population of expiratory neurones (21/39). 3. The expiratory neurones inhibited by ACh included neurones with axons projecting to the vagus or spinal cord, as well as neurones… CONTINUE READING
