Abstract:
Relationship between the blood level of calcium and the level of catecholamines in the brain limbic structures was studied in passive avoidance conditioning and extinction in rats with hypoparathyreosis. After parathyroidectomy, conditioning processes were shown to be impaired as a result of a disorder of calcium supply. In hypoparathyreosis, not only the basic dopamine and noradrenalin levels change, but catecholamine dynamics in learning and forced extinction of a passive avoidance reaction shifts. The results point to the deranged functioning of dopamine and noradrenaline brain systems as a result of disorders in calcium homeostasis. These shifts result in disorders of conditioning and development of an adaptive behavioral strategy.
