.... First, tetrodotoxin-sensitive inward rectification occurred during depolarization from rest to spike threshold. Second, 5 mmol l −1 tetraethylammonium (a K + channel blocker) induced plateau potentials that persisted in the presence of Mn 2+ or a low [Ca 2+ ] o but were blocked by a low [Na + ] o or 100...

... the interneurons in the ventilatory central pattern generator. This study demonstrates that the large-amplitude depolarization that underlies bursts of action potentials in ventilatory motor neurons is produced by a plateau potential. These motor neurons satisfy a number of the experimental tests that have been...

... action potentials can co-exist with plateau potentials. In neurones giving both plateau potentials and time-dependent action potentials, plateau potentials can drive action potentials in bursts. REFERENCES Goodman , C. S. and Heitler , W. J. ( 1979 ). Electrical properties of neurones...
