The Squid and its Giant Nerve Fiber


Getting a bit more anatomical for this post, we present a series of very cool old squid dissection films. When choosing to view the clips, please note that these are scientific dissections using squid cadavers.

"The Squid and its Giant Nerve Fiber" was filmed in the 1970s at Plymouth Marine Laboratory in England. This is the laboratory where Hodgkin and Huxley conducted experiments on the squid giant axon in the 1940s. Their experiments unraveled the mechanism of the action potential, and led to a Nobel Prize. Long out of print, the film is an historically important record of the voltage-clamp technique as developed by Hodgkin and Huxley, as well as an interesting glimpse at how the experiments were done. QuickTime video excerpts from the film are presented by the Smith College Dept. of Neurophysiology.
