WebHyperpolarization and depolarization. At rest, a typical neuron has a resting potential (potential across the membrane) of -60 −60 to -70 −70 millivolts. This means that the interior of the cell is negatively charged relative to the … free screenshot grabberWebThe depolarization of the neural axon during an action potential is driven by an influx of sodium ions, entering through voltage-gated sodium channels. Following this stage, voltage-gated potassium channels are stimulated, allowing potassium ions to exit the axon and causing hyperpolarization. farms for sale in oudtshoornWebVerified questions.
