â¢ When the axon hillock is depolarized to threshold, an action potential is generated. Voltage-gated. channels open, thereby increasing permeability of the neuron first to sodium and then to. potassium. â¢ As sodium moves rapidly into the neuron, it produces the rising phase of the action potential. â¢ As the inward movement of sodium slows and the outward movement of potassium increases, the. membrane repolarizes.
