  • Title: [Localization of areas of action potential generation in neurons of the edible snail].
    Author: Ierusalimskiĭ VN, Balaban PM.
    Journal: Neirofiziologiia; 1988; 20(1):90-8. PubMed ID: 3380214.
    Abstract:
    Site of origin of action potentials in silent and spontaneously active unipolar neurons of the snail Helix lucorum was established by stimulation of neurons isolated together with the initial part of the process from the neuropile by the sinusoidal extracellular current flowing along the soma-axon direction in the saline. The source of the spontaneous activity was in the neuronal process in all investigated neurons and one trigger zone usually dominated. Threshold of the action potential generation in response to the extracellular current in silent neurons was also connected with the axonal trigger zone activation. The low-threshold zone of action potential generation in the soma was found only in 20% of studied neurons.
