[The functional interrelationships of the components of the gastroduodenal complex and its afferent reactions].
The study was undertaken to study the functional relations between the overall electric activities of smooth muscles in 3 gastric portions (cardial and pyloric antrums, and the body of the stomach) and that of duodenal muscles during their direct electric stimulation, followed by the recording of potentials evoked in the feline cerebral cortex. There was an ambiguous correlation of the amplitudes of the electric activity of 4 portions of the gastroduodenal complex during opiate receptor activation and after vagotomy. The central and intraorgan components were found to play a combined role in displaying responses of gastroduodenal smooth muscles to opiate receptor stimulation and block.
