Terrestrial snails Helix are the strategic objects for the psychophysiological studies at the scientific school united by the research strategy “Human—Neuron—Model”. E.N. Sokolov considered studies of the snails’ neurons as very meaningful for the theory of psychophysiology. The unified spherical model developed by Sokolov using vectorial approach consists from the elements similar to the nerve cells. “Simpler nervous systems” of mollusks such the snails present a possibility for experimental testing of spherical model at the level of real neurons and synapses. A task of following talk is to present the results obtained at the snails’ neurons under leadership of E.N. Sokolov and the experiments that he planned for future studies of the spherical model at the level of neurons and synapses.
