[The role of the reticular formation at the hypothalamic level in regulating insulin secretion].

In cats, electric stimulation of direct microapplication of insulin to posterior hypothalamic nucleus increases the insulin content in the pancreatic venous blood independently of the concomitant changes of the blood sugar level. The insulin had no such effect in bilateral lesion of the lateral hypothalamus. Blockade of M-cholinergic system did not influence the changes of blood sugar level in these conditions. Electric stimulation of the anterior hypothalamic nucleus entailed no obvious changes of insulin and sugar level in the blood.
