<span>This hyperpolarization is due to the exiting of potassium ions or the influx of chloride ions through the channels in the neuron. During this time, the neuron enters a refractory period (approximately 2ms), during which an action potential is unable to be transmitted. After this timeframe, the neuron resets to around -70mV and the cell becomes able to re-transmit an action potential.</span>
