stimulation of the celiac neural bundle in the presence of hyperglycemia resulted in an inhibition of insulin release and in an augmentation of glucagon release . alpha-adrenergic stimulation resulted in a strong suppression of insulin secretion and a mild suppression of glucagon secretion . beta-adrenergic fiber stimulation caused a mild augmentation of both insulin and glucagon release , whereas the cholinergic fibers strongly stimulated both alpha- and beta-cell secretion .
