Selective participation of brain-specific nonhistone Np-3.5 proteins of chromatin in the processes of the reproduction of a defensive habit in response to food in edible snails.

The role of brain-specific nonhistone Np-3.5 proteins of chromatin in the processes of the reproduction of a developed defense habit in response to food was studied in preliminarily trained edible snails. It was found that gamma globulins to Np-3.5 over the course of tens of minutes suppress behavioral and neuronal reactions elicited by a specific conditional stimulus, carrot juice, while not altering the reaction to a different conditional stimulus, apple juice. The gamma globulins to other nonhistone proteins of chromatin did not exert an influence on the reproduction of habits of food rejection. It is hypothesized that brain-specific nonhistone Np-3.5 proteins of chromatin are selectively involved in the molecular processes supporting the neurophysiological mechanisms of the extraction of information from long-term memory.
