Question

The membrane potential of a neuron is measured from the inside of the cell relative to the outside. For a newly discovered neuron with properties that are not yet known, a researcher measures that the outside of this neuron is 60 mV more positive compared to the inside. What is the membrane potential?

Answer 1

In neurons, the inner surface of the membrane has a negative charge while the outer surface of the membrane has a positive charge causing the formation of the membrane potential. As the difference between the electrodes inside the cell and outside cell equals 60 mV, the membrane potential is -60 mV.
