WebRelative to the extracellular fluid, the membrane potential of a resting neuron is negatively charged at about -70 mV (see Figure 5). These are very small voltages compared to the voltages of batteries and sockets that we encounter every day, which range from 1 to 240V. WebA resting (non-signaling) neuron has a voltage across its membrane called the resting membrane potential, or simply the resting potential. The resting potential is determined by concentration gradients of ions across …
