  • Title: [Phase-dependent coordination of two motor programs in the buccal ganglion of a pteropod mollusk].
    Author: Norekian TP, Nikitin ES, Bravarenko NI, Malyshev AIu, Balaban PM.
    Journal: Zh Vyssh Nerv Deiat Im I P Pavlova; 2001; 51(6):717-22. PubMed ID: 11871036.
    Abstract:
    Rhythmic activities of two feeding structures of the pteropod mollusk Clione limacina, redula and hooks, controlled by the neural networks in the buccal ganglia must be coordinated in order to produce a meaningful feeding response. Optical recording from the buccal ganglia, which allows the simultaneous activities of numerous neurons to be traced, revealed that such coordination exists in a phase-dependent manner. Instead of recording four theoretically possible phases of neuronal rhythmic activity, we always recorded only two phases, even after the electrical stimulation of the cerebro-buccal connective, which triggers both radula and hook rhythmic movements in the preparation.
