Typically, the voltage of a resting neuron is -60 to -70 millivolts (mV). This voltage fluctuates according to the strength of an incoming stimulus.

WebThe resting membrane potential is the potential difference between the inside of a neuron and the extracellular fluid that the neuron is. In other words, the inside of the neuron is negatively charged relative to the outside of it. This is achieved primarily via the ATP-K+-Na+ active transporter, which uses 1 ATP molecule to send out 3Na+ ions ...
