(1) The oscillatory network underlying centrally programmed feeding in the fresh water pulmonate, Helisoma trivolvis, was studied using intracellular recording and staining techniques. These premotor neurons have been termed cyberchron neurons. (2) Intracellular staining with Procoin yellow has allowed the construction of a soma map and tentative identification of axonal projections of the cyberchron neurons. (3) Cyberchron neurons form a tightly electrically coupled network. Coupling coefficients range from 0.15 to 0.5, and electrotonic junctions allow the passage of Procion dye from cell to cell. Electrical synapses act as low pass filters, and allow spatial and temporal summation. (4) Burst generation within the network is the result of network interaction manifest as regeneration positive feedback from neuron to neuron via attenuating electrical synapses. (5) Decreased coupling between cyberchron neurons during and immediately following a burst is observed, and is discussed as a possible mechanism for burst termination.
