Staining the cells of the nervous system
Camillo Golgi (1843 –1926) was an Italian biologist and pathologist, now recognized as the greatest neuroscientist of his time. He studied and worked at the University of Pavia, where he developed a technique of using potassium dichromate and silver nitrate to stain cellular components black. Using this stain he was able to discover the organelle now known as the Golgi apparatus, consisting…
