Video from Neuroscientifically Challenged on YouTube

5.8.2 Explain threshold, depolarisation, repolarisation and after-hyperpolarisation in terms of ionic conductances.

The part on this line: 4:18–7:20

Why this video

Explains how the sequential opening, inactivation, and closing of voltage-gated sodium and potassium channels drive threshold, depolarisation, repolarisation, and hyperpolarisation.

Heads up

Check the specific voltage values against course conventions, where resting potential is -70 mV, threshold is -55 mV, and peak overshoot reaches +35 mV.
