  • Title: [The selective participation of brain-specific non-histone proteins of chromatin Np-3,5 during the reproduction of a defensive habit to food in edible snails].

    Abstract:
    The role of brain-specific nonhistone proteins of chromatine Np-3.5 in the processes of reproduction of elaborated defensive habit to food was studied in previously learning snails. It was found, that gamma-globulines to Np-3.5 during tens of minutes inhibited behavioural and neuronal reactions elicited by a definite conditioned stimulus--carrot juice, without changing reactions to other conditioned stimulus--apple juice. gamma-globulines to other nonhistone proteins of chromatine did not influence the reproduction of food rejection habits. It was supposed that brain-specific nonhistone proteins of chromatine Np-3.5 were selectively involved in the molecular processes providing for neurophysiological mechanisms of information extraction from the long-term memory.
