    • @PsychExplained
      @PsychExplained  9 місяців тому

      Potassium channels open in response to depolarization, allowing potassium ions to move out of the cell down their concentration gradient. This efflux of potassium ions helps restore the negative charge inside the cell. Sodium channels that opened during depolarization begin to close, reducing the influx of sodium ions into the cell. This decreases the positive charge inside the cell. As a result of these processes, the ion gradients across the cell membrane gradually return to their resting state, with potassium ions predominantly inside the cell and sodium ions predominantly outside. This restoration of ion gradients allows the neuron to prepare for subsequent action potentials and maintain its resting membrane potential.

    Why is the voltage at -70 inside at the start? If potassium is positive, what else is in the neuron that's so negative? Great video btw, thank you!

    • @PsychExplained
      @PsychExplained  9 місяців тому

      The resting membrane potential of approximately -70 millivolts (mV) inside a neuron at rest is primarily due to the differential distribution of ions across the cell membrane, particularly potassium (K+) and sodium (Na+), as well as the selective permeability of the membrane to these ions.
