Neuronal Action Potentials
by Anonymous
See how the sodium-potassium pump maintains the resting potential, explore the five stages of an action potential, and discover the all-or-none response that fires only after crossing the threshold.

About this app
The Action Potential of a Neuron is an interactive biology learning app about resting potential, action potential phases, and the all-or-none principle. Explore how the sodium-potassium pump maintains approximately −70 mV, follow the membrane potential from threshold through depolarisation, repolarisation, and hyperpolarisation, and compare responses to stimuli of different strengths.
Use cases
- High school biology students studying neurons and membrane potential
- Teachers demonstrating action potential concepts in class
- Learners reviewing Life Science I topics interactively
- Science experiment activities comparing threshold and spike frequency
Features
- Toggle the sodium-potassium pump and advance time to observe resting potential changes
- Step through resting, threshold, peak, repolarisation, and hyperpolarisation phases
- View sodium entering and potassium leaving during the action potential
- Adjust stimulus strength to test whether signals fire
- Compare all-or-none spike size with changes in firing count
- Complete guided missions in each learning section
