    Abstract:
    Application of desglycine-argininvasopressin (DG-AVP) differently influenced different types of cells of snail isolated central nervous system. In neurosecretory cells an increase of spontaneous impulse activity took place and, as a rule, bursts of impulses appeared, most often of synaptic origin, excluding PPa1 neurones and one of the neurosecretory cells of the left parietal ganglion. The increase of the bursts activity in these cells was based on the increase of the amplitude of membrane potential waves. Under the influence of neurosecretory cells system activation, EPSPs frequency and amplitude in secondary-sensory neurones increased, which led to a greater probability of the action potentials appearance. At prolonged action the spontaneous EPSPs in these cells began to group in bursts. Excitability and membrane resistance of these cells remained unchanged. DG-AVP had no influence on primary-sensory neurones and motoneurones.
