Variations of the voltage clamp technique: Two-electrode voltage clamp using microelectrodes, Single-electrode voltage clamp, Continuous single-electrode clamp (SEV-c) (aka patch clamp technique), Discontinuous single-electrode voltage-clamp,
Technique "used by electrophysiologists to measure the ion currents across the membrane of excitable cells, such as neurons, while holding the membrane voltage at a set level. Cell membranes of excitable cells contain many different kinds of ion channels, some of which are voltage gated. The voltage clamp allows the membrane voltage to be manipulated independently of the ionic currents, allowing the current-voltage relationships of membrane channels to be studied.[1] [1] Kandel ER, Schwartz JH, Jessell TM [2000] Principles of Neural Science, 4th ed. pp.152-153.
