Biology - Neuroscience - Basic - Neurons and nerve impulses - Action Potential Simulator
An interactive neuron showing the action potential. Display a section of axon membrane with Na⁺ and K⁺ ion channels. A 'Stimulate' button triggers the sequence. Show membrane potential changing on a voltage graph (-70mV resting → +30mV depolarized → -90mV hyperpolarized → -70mV back to resting). Ste
