[Mechanisms of central regulation of blood sugar content].
Acute experiments were conducted on adult cats. Injection of insulin microdose (0.025 U/kg with 0.025 ml of saline) into the posterior hypothalamic nucleus caused an increase in the blood sugar level 10 and 70 min after the injection. Changes of the blood sugar level correlated with the EEG activation of the posterior hypothalamic nucleus in response to the insulin injection, spreading to the lateral hypothalamus. However, hormonal stimulation of the posterior hypothalamic nucleus against the background of bilateral coagulation of the lateral hypothalamus produced no increase in the blood sugar level in 10 min. This is indicative of the participation of the lateral hypothalamus in the realization of hyperglycemic reactions in response to the insulin injection into the posterior hypothalamic nucleus.
