Neuronal Currents (s) having Bath application of Pb2+ shifted the neurons'' current-voltage relation in patch-clamp recording from acutely isolated pyramidal neurons. These results were interpreted to "demonstrate that Pb2+ in micromolar concentration is a voltage-dependent, reversible blocker of delayed-rectifier potassium currents of hippocampal neurons" as Publication facts
