Epidermal cells that identify colors, transmit radio waves, and process information. The skin's job is not just to feel. The skin is a thinking circuit comparable to the brain, still unknown. There are many organisms without brains, but there are no multicellular organisms without skin. A science essay discussing the potential of the skin, the most important organ. ■ Author: Mitsuhiro Denda Chief Researcher, Shiseido Life Science Research Center. Born in 1960.
