title: [Participation of the calcium-binding membrane components in the neurophysiologic mechanisms of habituation in the edible snail].
abstract: The native dynamics of Ca2+ binding with the membrane components in functionally different neurons of Helix pomatia when producing habituation to tactile stimuli are studied by fluorescent chlortetracyclin method. In the command neurons of the defensive behavior the weakening of the electrophysiological response characteristic for habituation and a decrease in the Ca2+ content were found. An increase in the Ca2+ content was found in supposed sensory neuron and in motoneurons in case of tactile stimulation, but according to electrophysiological criteria the habituation development in these cells was impeded. It is supposed that production of habituation is followed by hydrophobic-hydrophilic translocations of Ca2+-binding molecules in nerve cells.
