[Neurochemical analysis of the brain structures in the formation of adaptive behavior in chicken embryogenesis].

Studies have been made on the rate of biosynthesis of high molecular and neurospecific proteins in the hippocamp and archistriatum of chick embryos during the formation of adaptive changes in motor activity under controlled experimental conditions and unmonitored occasional stimulation. It was shown that during uncontrolled sensory stress the rate of synthesis of high molecular and neurospecific proteins in the structures investigated is increased whereas during learning these changes are absent.
