Abstract:

Certain input-output relations were studied by way of intraneuronal recordings in isolated visceral ganglia of Aplysia californica. All cells exhibited a prolonged sequence of excitatory postsynaptic potentials EPSPs of a single type and, as a consequence, produced recurrent spikes. EPSPs either 1 occurred spontaneously or 2 were initiated by stimulating a connective with shocks from a stimulator driven by a Geiger counter. The prespike epoch was analyzed and the events that trigger the postsynaptic spike were identified in a probabilistic manner. Experiments in digital-computer-simulated neurons reproduced and extended the results of animal experiments.
