Often called the “father of modern neuroscience,”Santiago Ramón y Cajal was a Spanish scientist whose exquisitely detailed drawings helped to reveal the pathways,cells and structure of the brain. Born in 1852, Cajal crafted illustrations, based on painstaking observations of brain slices under the microscope, that led to major discoveries long before neuroimaging was possible. He realized, for instance, that the brain was a vast network of individual neurons—a inding that led him to earn a Nobel Prize in 1906. In this largeformat book, 82 of Cajal’s drawings are paired with commentary and essaysfrom neuroscientists celebrating both the scientiic value and the pure artistry of his work.
