Which is the normal sign of the electric charge between the two sides of the neuron plasma membrane? What is the potential difference (voltage) generated between these two sides? What is that voltage called?
As in most cells the region just outside the surface of the neuron plasma membrane presents a positive electrical charge in relation to the region just inside that thus is negative. The normal (at rest) potential difference across the neuron membrane is about – 70 mV (millivolts). This voltage is called the resting potential of the neuron.
