When a nerve impulse (which is how neurons communicate with one another) is sent out from a cell body, the sodium channels in the cell membrane open and the positive sodium cells surge into the cell. Once the cell reaches a certain threshold, an action potential will fire, sending the electrical signal down the axon. See more When a neuron is not sending signals, the inside of the neuron has a negative charge relative to the positive charge outside the cell.
