Explain neurophysiology with a simple example

The short version: neurophysiology refers to how neurons generate and transmit electrical and chemical signals. A quick example makes it concrete — Sodium influx drives depolarisation; potassium efflux restores the resting state.

How to approach it step by step

Once one example makes sense, the method generalises: track ion movements across the membrane through each phase of the action potential. In a visual interactive session the example is built on screen piece by piece, so you see which quantity changes at each step instead of only reading a final answer. Ask for a harder variant and the explanation adapts on the spot.

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.
