Description
The effects of the feeding and satiety centres on gastric motility were studied in anesthetized rats by electrically stimulating these centres and recording the intragastric pressure. The results were as follow: (1) There was no difference in the discharges of the feeding and satiety centres between 8 Gy irradiated rats and the controls. (2) Stimulation of the satiety centre elicited chiefly inhibition, whereas that of the feeding centre excitation of gastric motility in normal rats; (3) On the 2nd to 4th day after 8 Gy irradiation stimulation of both the feeding and satiety centres usually revealed inhibition of gastric motility. The above results indicate that the inhibition of gastric motility after irradiation is independent of the activities of feeding and satiety centres
