[Effect of an acute lesion on afferent reactions of the stomach and duodenum]

By recording the evoked potentials in the cortex and thalamic nuclei, afferent reactions of gastroduodenal components were studied early after acute gastroduodenal lesion in acute feline experiments. A model of acute ulcer in various gastric portions and the duodenal bulb gave rise to inhibition of their afferentation. This phenomenon was most pronounced in pyloric ulcer. It is concluded that the inhibition of the afferent reactions of gastroduodenal components in early periods after their acute lesion is a specific protective reaction of the viscera and appears mainly at the intraorgan level.
