Blocking of the axon spikes by pentylenetetrazol in an identified neuron of the snail Helix lucorum, with consequent induction of epileptic activity in the cell body of the same neuron.

abstract：:Following peripheral nerve section, the cell body and proximal axon undergo various physiological and morphological changes which may be associated with regrowth. We found that axotomy reduced the amplitude and duration of the afterhyperpolarization (AHP) of the action potential (AP) of bullfrog sympathetic neurones. ...
