Sign of electric charge between two sides of neuron plasma

Question

Which is the normal sign of electric charge between two sides of neuron plasma membrane? Describe potential difference (voltage) generated between these two sides? What is that voltage called?

Answer 1

As in most cells region just outside the surface of neuron plasma membrane presents a positive electrical charge in relation to region just inside that consequently is negative.The normal (at rest) potential differentiation across the neuron membrane is about –70 mV (millivolts). This voltage is called the resting potential of neuron.
