The (Resting) Membrane Potential
The baseline difference in electrical charge between the inside of the neuron and the exterior is typically -70 millivolts and is called the resting membrane potential, sometimes just called the resting potential. This value can vary slightly in different neurons and in different animal species, but most mammalian species have a resting potential of -70 millivolts. The inside of the neuron is just slightly more negative than the outside of the cell; -70 millivolts is -0.07 volts, less than one-tenth of a volt. The establishment of the resting potential is generated by moving electrically charged ions against their chemical concentration gradients or against their electrical gradients or sometimes both gradients. The concentration gradient is determined by simple chemical diffusion, i.e., that atoms or molecules tend to move from regions of higher concentration to lower concentration. The higher the concentration of a chemical, the stronger the diffusion force is pushing all the atoms or molecules of that chemical away from each other. Hence, the higher the concentration, the greater the energy needed to resist or overcome the diffusion force. The electrical gradient is present because the atoms or molecules being moved across the neuronal membranes carry either positive or negative electric charges. Like charges repel each other. When particles of similar (same sign) charge are moved physically closer together, energy is required to overcome the electrical repulsion between those similarly charged particles.
