Convulsants (benzylpenicillin and pentylenetetrazol) on potential clamped myelinated axons from the rat.
Brismar T., Jefferys JG.
The effect of two convulsants, benzylpenicillin and pentylenetetrazol, was tested in potential clamp experiments on single rat myelinated nerve fibres. 10 mM concentrations did not affect the permeability properties of the nodal membrane. The convulsive action is therefore probably not mediated through changes in the excitability of central axons.
