528:. The change of color is activated by an action potential traveling through the cephalopod skin. Because all neural activity in biological systems are controlled by the propagation of action potentials, neuroscientists are especially interested in this visual representation of action potential propagation. Cuttlefish have a mode of color change typified by dark bands traveling across the animal's body in a coordinated pattern called "passing clouds". The paintpot cuttlefish is especially conducive to this kind of research due to their small size, slow speed and the frequency of the passing clouds display. The results of this study concluded that the passing clouds phenomenon was a result of central wave generation indicating that the action potential originated at a single point controller. This may indicate that cephalopods may have a
