Viewing the brain through the master hand of Ramon y Cajal


For most neuroscientists, the roots of our discipline stem from Santiago Ramón y Cajal, the Spanish scientist who, during almost half a century of patient work, showed that the nervous system is made up of independent nerve cells. His studies on the anatomical organization of the brain are still a source of inspiration for many of us. His monumental body of work fully justifies that Ramón y Cajal be singled out as the founder of modern neuroscience.
