Exocytosis inhibitor Exo 1 potentiates depression of acetylcholine-induced inward current in defensive behavior command neurons of edible snail, when acetylcholine is applied rhythmically to the soma in cellular correlate of habituation. A mathematical model presupposing different receptor localization in the cell and regularities of their translocations made it possible to analyze the dependence of acetylcholine-induced current depression on a number of intracellular processes. It was concluded that depression of choline-sensitive extrasynaptic zones on the membrane of defensive behavior command neurons in edible snail in cellular correlate of habituation is partially determined by attenuation of exocytosis of internalized cholinergic receptors.
