Insane in the Chromatophores

from the page

During experiments on the axons of the longfin squid in Woods Hole, we were taken in by the beauty of the fast changing color of the skin. The squid’s skin contains many colorful light-reflecting cells called chromatophores. We wanted to try to stimulate the fin nerve directly from our iPod. The results were both interesting and beautiful.

The video is a view through an 8x microscope zoomed in on the dorsal side of the squid’s fin. We used a suction electrode to stimulate the fin nerve.

More details can be found here: Backyard Brains
and an explanation of how it works can be found on our TED talk.

A good portion of the Lab just returned home from Dragon*Con which was a blast. This is a nice cross-section of the cosplay there.
