When a neuron is at its resting state, the inside of the cell membrane is negatively charged (due to the presence of negatively charged proteins and other biomolecules), while the outside is positively charged (due to the presence of positively charged ions such as Na+ and K+). This separation of charges creates an electrical potential, with the inside of the neuron being about 70 millivolts more negative than the outside. This electrical potential is called the resting potential.
