Interactive neurophysiology simulations. No downloads required. Interact with Hodgkin & Huxley model neuron in both current and voltage clamp modes. Simulate current inject into passive membrane (RC Circuit simulation). Easy to use for students of neurophysiology without having to code models themselves. Useful for professors to demonstrate concepts live. JavaScript source code for Hodgkin Huxley and Passive membrane simulations available on my github Adding Goldman Hodgkin Katz and interactive
