Who developed the Golgi stain that allowed visualization of individual neurons?

• A. Santiago Ramón y Cajal
• B. Camillo Golgi
• C. Paul Broca
• D. Karl Wernicke

Answer: (B)

Seeing entire neurons in tissue comes from the Golgi staining method, developed by Camillo Golgi. This silver impregnation technique colors a small, random subset of neurons in their full morphology, so you can trace the cell body, dendrites, and axon within a single stained cell. That clear, complete view made it possible to study neuronal structure in detail and laid the groundwork for understanding how neurons are organized. Ramón y Cajal later used Golgi’s stain to argue for the neuron doctrine, but he didn’t create the staining method himself.
