“…in 1887, Spanish neuroanatomist Santiago Ramón y Cajal learned about Golgi’s black reaction from psychiatrist Luis Simarro Lacabra, who had managed to improve Golgi’s original technique. Cajal, who was already obsessed with studying the structures of living tissues in minute detail, immediately recognized the black reaction as the most sophisticated way to investigate the nervous system and puzzled at why so few scientists apart from Golgi himself had tried out the staining procedure. Cajal further improved the black reaction and applied the technique to all kinds of nervous tissue from different animals and from people, producing beautiful and detailed sketches of what he saw under the microscope—drawings that scientists and educators still rely on today.”
