[The effect of microinjections of bombesin into the amygdala on the slow-wave frequency of the gastroduodenal smooth muscles and on the migrating myoelectric complex].
In dogs with electrodes implanted in the smooth muscle wall of the stomach and duodenum, microinjection of bombesin (5 micrograms) during the 2nd phase of the migrating myoelectric complex decreased frequency of slow waves in the stomach, leaving unaltered the frequency of slow waves in the duodenum. Bombesin caused a short-term inhibition of the gastric and intestinal spike activity followed by its increase, the active period of the migrating myoelectric complex being prolonged.
