How does a voltage clamp work?
A) It measures the voltage of a neuron that is placed in the preparation.
B) It changes the membrane potential of a neuron using two extracellular electrodes.
C) It holds the current across a neuronal membrane constant and measures the changes in voltage.
D) It holds the voltage of a neuron constant by injecting current equal to the ionic current passing across the cell membrane.
E) It inactivates ion channels so that the only current passing into the cell is delivered by the equipment.
