The feeding responses evoked by cholecystokinin are mediated by vagus and splanchnic nerves

► Effects of VGX and CMGX on the feeding responses by CCK-8 and 33 were tested. ► Reduction of meal size (MS) by CCK-8 and 33 is mediated by the vagus. ► Prolongation of IMI by CCK-33 is mediated by celiaco-mesenteric ganglia. ► Both neuronal components are required in mediating feeding responses by CCK.
