title: [Integrated processes in an identified edible snail neuron possessing 2 trigger zones].
abstract: The paper deals with the distribution of spikes in different axonal branches of one and the same identified neurone of Helix pomatia. It is shown that the identified neurone possesses at least two triggering zones: one -- in the soma, and the other -- on one of the axones. Consequently, spikes travelling along this axone are more numerous than those entering other axonal branches. At the same time the number of the spikes entering axonal branches depends on the state of the neurone itself and may be smaller than AP number recorded in the soma. This suggests a special intraneuronal mechanism of local plasticity. The paper discusses the role of giant neurones in the integrative activity of molluscs CNS.
