In this experiment, a group of scientists hooked up electrodes to a longfin inland squid, and then watched as it changed color to Cypress Hill’s Insane in the membrane.
During experiments on the axons of the Woods Hole squid (loligo pealei), we tested our cockroach leg stimulus protocol on the squid’s chromatophores. The results were both interesting and beautiful. The video is a view through an 8x microscope zoomed in on the dorsal side of the caudal fin of the squid. We used a suction electrode to stimulate the fin nerve.
