The father of modern neuroscience, Santiago Ramón y Cajal, drew masterful sketches of the brain.
He was an artist trapped in a laboratory.
But where the Renaissance master goes sensual, macro, and dynamic, the Spaniard zeros in, mapping the miraculously microscopic using new methods of staining slide tissues that isolated single cells under the microscope. In this way, Cajal drew the newly visible synaptic networks of the brain and discovered a breakthrough that proved that neurons are in touch without touching. These results changed neuroscience. His work is still widely used as a teaching device.
