1 (The One-Electrode Voltage Clamp)). 6. However, all of these variants have in common that the voltage-clamped membrane, either from a whole cell or from a membrane patch, has a resistance in the range of GΩ. 5 and 50 MΩ, voltage control can be achieved with only one electrode that measures potential and passes current simultaneously. 24 gives a schematic representation of the minimum electronic circuit. One can derive the circuit for the patch-clamp method from that of the two-electrode method simply by omitting the current electrode and connecting the output of the negativefeedback op-amp back to the "voltage-electrode" via a resistor (feedback resistor).

For working with intact cells, microelectrodes (first introduced by Ling and Gerard 1949) must be used. 13). This allows penetration of the cell membrane without much harm to the cell. The electrical contact between cytoplasm and the electronics is achieved by filling the capillaries with an electrolyte solution and via the Ag/AgCl connection. As electrolyte solution a highly concentrated (3 M) KCl solution is often used. This brings the resistances of such pipettes down to the MΩ range, and makes liquid-junction potentials occurring at the tip of the electrode (due to the similar mobility of potassium and chloride ions) nearly independent of changes in the composition of the outer solution.

For the completely excited cell, the potential difference will again be zero; now the cell surface is continuously negative. With this kind of extracellular recording, we cannot distinguish whether the entire cell is at rest or completely excited. This statement is also true for the heart when recording an ECG; only time- and space-dependent changes can be detected. 2 • Example (ECG) .. 5a,b a The symbolized heart as a dipole in the centre of an electrolyte container.
