Gated ionic channels and the mechanism of excitability.
Fluctuating ionic currents caused by the activation of individual ionic channels can be observed in excitable membranes. These single-channel currents allow experimenters to characterize the stochastic properties of the membrane protein conformational transitions that underlie excitation. This exact characterization is leading to a new level of precision in the description of excitable cell behavior throughout the nervous system.
