This is the picture of the first intracellular recording of the action potential, or the nerve impulse. It was taken from the giant axon from a squid, because the axons of the neurons of squid are really large, like visible to the naked eye, large. Back in 1939, electrodes weren’t as good as they are now so they had to make do with working with these large axons. However, this was such an important recording that you’ll probably notice the waveform in any respectable textbook that tries to explain nervous function (whether it be at a basic or advanced level). This was such an important discovery that Hodgkin and Huxley, the people who got made this measurement, got the Nobel Prize in 1963 (along with another dude called Eccles).
The discovery of the action potential is possibly one of the most important discoveries of the 20th century, as it’s the basis of neuroscience, intelligence, consciousness, the mind, perception of reality, neurology, psychology and psychiatry… the list goes on.

Hodgkin and Huxley (and Eccles), top lads.
