Voltage-clamp analysis of the sodium and potassium currents in skeletal muscle fibres treated with 4-aminopyridine

J Molgó. Experientia. .

Abstract

External application of low concentrations of 4-aminopyridine blocks potassium currents without affecting sodium currents in pieces of single frog skeletal muscle fibres. The blockade of potassium currents was voltage-dependent, being partially relieved on depolarization.
