Abstract
Summary
Electrically induced convulsions produce a hyperglycemia in the normal, a hypoglycemia in the adrenalectomized rat, and no change in blood sugar in adrenalectomized-vagotomized animals. This is interpreted to mean that the convulsions excite both the sympathetico-adrenal and vago-insulin systems. The effect on the former predominates over that on the latter. If a normal animal the vagi are cut below the diaphragm and therefore the secretion of insulin can no longer be controlled by the vagus, it is found that the hyperglycemic response is greater than in control animals in which the vagi are intact.
