The action potential is started when the membrane is very slightly ‘depolarised’‚ meaning that the charges inside and outside the cell become more similar. This happens when a stimulus causes a small influx of sodium ions into the cell. For an action potential to occur‚ the voltage has to pass a threshold value of -58mV. at this point‚ in a cycle of positive feedback‚ the action potential will always occur. Once the threshold value has been reached
