Action Potential Lab: Experiment with a squid neuron

Welcome to the Action Potential Lab!

In this simulation, you will learn about the propagation of an action potential along the membrane of the axon of a neuron. To do this you will extract the giant axon from a squid and use electrodes to send various electric signals to observe their effects.
