A non-synaptic spread of excitation between neighboured neurons was studied in a model nervous system using epileptiform activity. The identified giant neuron B3 in the buccal ganglia of Helix pomatia reliably generated paroxysmal depolarization shifts (PDS) when treated with pentylenetetrazol or etomidate. Simultaneous recordings of neuron B3 and other neurons showed that each PDS in neuron B3 was accompanied by a depolarization in the other neurons. These related depolarizations (PDS-RD… CONTINUE READING
