Action Potential Experiments

Action Potential Experiments is a demonstration/simulation laboratory for neurophysiology based on the "sodium theory" as originally formulated and tested by A. L. Hodgkin and his colleagues. The application includes simulations of the original experiments of Hodgkins and his colleagues, and of the classic voltage clamp and patch clamp experiments and an animated illustration of the "sodium theory" explanation of Nernst potentials for potassium and sodium ions. The student can perform simple ion concentration experiments to test the predictions of the theory.
