1. 1. The characteristic activity pattern of the bimodal pacemaker neuron (RPal) of Helix pomatia was temporarily inhibited by synaptic input, both in isolated ganglion by electrical stimulation of nerves and in brain-heart preparation by tactile stimulation of peripheral receptors. 2. 2. Intracellular injection or extracellular application of SH blockers changed bursting of the RPal neuron. Hyperpolarizing phases were absent while the cell generated action potentials in a normal way, or, slow waving was present without generation of action potentials. 3. 3. It is suggested that slow oscillation of the membrane potential is based on an intracellular metabolic cycle, which is independent of spike generation.
