You are performing a voltage clamp experiment in which the neuron's resting potential is -70 mV. When you change the command voltage to + 40 mV, what is the first current that you observe?

Question

Quizplus · Accepted Answer

The first current observed during a voltage clamp experiment when the command voltage is changed from a resting potential of -70 mV to +40 mV is the capacitative current. This is because the initial response to a sudden change in voltage is the charging of the cell membrane's capacitance, which behaves like a capacitor.
