Summary

In chap. 5 we discussed the selectivity of ion channels and the ion permeation process in detail. Another important property of pores is the kinetics of their opening and closing, their gating behavior. We had already addressed this property when we discussed the characterization of individual channels using the patch-clamp technique and the analysis of current fluctuations and gating currents. The patch-clamp technique in particular has expanded the understanding of electrophysiological phenomena to include a new “microscopic” dimension. In the following we want to consider a phenomenon called excitability, the elucidation of which, although on a macroscopic level, represented a milestone in electrophysiology. In this context, macroscopic means that a large number of simultaneous single channel events contribute to the measured signal.
