Set the baseline
Define the resting state, relevant gradient and membrane property. A change makes sense only against its starting condition.
EXCITABLE TISSUE
Start the signal.
Trace the response.
Use this framework to understand membrane behaviour and propagation before adding detailed channel facts, values and diagrams from lawful approved sources.
Cross the threshold
Connect stimulus, threshold behaviour and the initiating membrane event. State the model’s assumptions rather than treating a threshold as universal.
Follow propagation
Trace how local change becomes a travelling signal and which structural features alter its speed or reliability.
Explain recovery
Connect restoration, refractoriness and readiness for the next signal. Time is central to both the curve and function.
RECALL CHECK
Can you explain the sequence?
Try the original check, then add detailed source-backed channel and waveform facts in your own notes.
