[Electrical connection between 2 bursting neurons in Helix pomatia].
In the parietal ganglion of some Helix pomatia snails two neurons with fast bursting activity were found instead of a single RPa1 neuron. Simultaneous recording of the activity from these neurons showed an almost complete synchronization of the membrane potential waves. Direct de- or hyperpolarization of the membrane of one of the neurons (either) resulted in de- or hyperpolarization of the other. Synchronous spontaneous modulation of electrical activity of the two neurons was also observed as well as synchronous modulation caused by the addition of a modulating factor to the external solution. Electrical coupling between these neurons is postulated.
