  1. Membrane potential (resting membrane potential) (article) - Khan …

    In this article, we'll see how a neuron establishes and maintains a stable voltage across its membrane – that is, a resting membrane potential.

  2. Neuron action potentials: The creation of a brain signal

    During the resting state (before an action potential occurs) all of the gated sodium and potassium channels are closed. These gated channels are different from the leakage channels, and only …

  3. Neuron resting potential mechanism (video) | Khan Academy

    This video explores the creation of neuron resting potential and its relation to ion concentration differences. It highlights the role of organic anions, sodium potassium pump, and leak channels.

  4. Khan Academy

    Learn about depolarization, hyperpolarization, and action potentials in neurons with Khan Academy's comprehensive biology resources.

  5. Neuron resting potential description (video) | Khan Academy

    Explore the neuron resting membrane potential, a stable charge separation across the cell membrane. Discover the roles of anions and cations, and how their concentration differences …

  6. Depolarization, hyperpolarization & neuron action potentials …

    At rest, a typical neuron has a resting potential (potential across the membrane) of 60 to 70 millivolts. This means that the interior of the cell is negatively charged relative to the outside.

  9. Neuron action potential mechanism - Khan Academy

    Explore the role of voltage-gated ion channels and how they open when the membrane potential crosses a threshold value, as well as the influx of sodium ions and efflux of potassium ions …

  10. Electrotonic and action potentials (video) | Khan Academy

    We've already seen that when a neuron is in its resting state there's a voltage difference across the membrane. And so in these diagrams right over here, this right over here is the membrane.
