Indian Journal of Physiology and Pharmacology. 1990 Apr; 34(2): 105-8http://imsear.searo.who.int/handle/123456789/108811Learning behaviour under different glycaemic conditions were studied in albino rats using an avoidance box. When insulin and glucose levels were low after fasting, animals showed delay in avoidance learning. But there was no change in acquisition of learning after hypoglacaemia induced by insulin. This difference in behaviour under hypoglycaemia of almost similar severity is possibly due to difference in its rate of induction and activation of counter regulatory neuro-endocrine mechanisms. Diabetic (alloxan) rats failed to improve learning. Besides, hyperglycemia, other factors like metabolic disturbances, cytotoxic effects of alloxan may have inhibited learning in this group. Hypo or hyperglycemia disturb the function of neuronal substrates responsible for learning and memory.engAnimalsAvoidance Learning --drug effectsBlood Glucose --metabolismDiabetes Mellitus, Experimental --psychologyHyperglycemia --psychologyHypoglycemia --psychologyInsulin --pharmacologyMaleRatsJournal Article
