Transfer of conditioned reflex hypoglycemia in dogs

Conditioned hypoglycemia was induced by intravenous injection of a 20% glucose solution to donor dogs. In control tests the dogs were injected the same volume of 0.9% saline. Then 0.5 ml of cerebrospinal fluid from donor animals was injected into suboccipital cisterna of recipient dogs. 24 hours later the recipient animals were exposed to the conditioned signal and injected physiological saline. It has been demonstrated that hypoglycemic response in recipient and donor dogs was identical, the reactions retained in the recipient dogs for 5-7 days after the liquor administration.
