Summary The effect of selective denervation of the pyloric antrum on secretory response to three types of food was determined in 3 dogs with innervated and 4 with denervated stomach pouches. With the antrum in situ this procedure has surprisingly little effect on the total meal responses in innervated pouches, on the variation in response induced by altered buffering capacity of the meals, or on the effect of subsequent vagotomy. However, the antrum appears less sensitive to local stimuli after denervation, as evidenced by the reduced meal response from the denervated indicator pouch after denervation of the antrum.
