R. Douglas Fields, PhD, is Chief of the Nervous System Development and Plasticity Section at the National Institute of Child Health and Human Development. He is also Editor-in-Chief of the journal Neuron Glia Biology and author of "The Other Brain," about glial cells in the brain that do not communicate using electricity but that support neurons. In the Scientific American (May 27, 2010) an article by Fields is entitled, "Michelangelo's secret message in the Sistine Chapel: A juxtaposition of God and the human brain." You may enjoy reading about Michelangelo and "his hidden anatomical illustrations" that have been found—painted on the ceiling of the Sistine Chapel (notably, sketches of brain anatomy.)
