An investigation was made into the links between electric activity of antral and of duodeno-jejunal musculature in different functional conditions. The function of the gastroduodenal junction in this linking mechanism was analysed. The following observations were made: (a) in the absence of gastric stimulation, the slow electric activities of stomach and duodenum appear to be completely independent; (b) the gastroduodenal junction evidences no electric activity of its own but is affected by that of the two adjacent structures; (c) chemical stimulation of the gastric mucosa causes activation of the electric and mechanical activity of the stomach and analogous activation of duodenal musculature; this effect is mediated by the gastroduodenal junction; (d) very probably, the transmission of gastric activation to the duodenum is myogenic for it ceases after surgical transection but not after cooling or after ligature. The possible functional role of the pyloric junction in the complex gastroduodenal mechanism is discussed.
