[The preprogramming of behavior patterns by changing the neurotransmitter metabolism in the early postnatal ontogenesis of albino rats].
Changes in neurotransmitter concentrations, which are brought about by the administration of neurotropic pharmaceuticals to albino rats at the time of differentiation of the brain, may have a lasting effect upon the reactivity and adaptability of adult animals to environmental factors and give rise to specific patterns of behavior. 1. Pargyline, when administered neonatally, resulted in a reduction of learning power, decrease in the power of retention, as well as reduction of the decision-making ability. 2. Reserpine gave an improvement of learning power, but simultaneously decreased both the power of retaining what had been learnt and the decision-making ability. 3. Pyridostigmine gave a marked improvement of adaptability which was evidenced in higher learning power, greater retentiveness, and better decision-making ability.
