Action Potentials from Squid featuring Alan Hodgkin

This movie is from the early 1970's made at the Marine Biological Labs at Plymouth, UK. Demonstration of the Voltage Clamp technique and the basic ionic mechanisms that underlie the resting potential and the action potential in a giant squid axon. P. F. Baker and A. Hodgkin demonstrate the experiment. These discoveries earned Hodgkin and Huxley the 1963 Nobel Prize in Physiology or Medicine.
