What is neurophysiology in medical sciences?

In medical sciences, neurophysiology refers to how neurons generate and transmit electrical and chemical signals. It matters because the same idea reappears across many later topics, so building a clear mental picture of it early saves a lot of time.

How to approach it step by step

To work with neurophysiology confidently, track ion movements across the membrane through each phase of the action potential. LetMeTeach draws this out live on screen while explaining it aloud, so you watch each part appear instead of decoding a static block of text. You can interrupt at any point and ask for the same idea again in simpler words, in another language, or with a different example.

Worked example

Sodium influx drives depolarisation; potassium efflux restores the resting state.

The mistake most learners make

Believing the action potential varies in size with stimulus strength.
