Golgi Stain

The Golgi stain is a special laboratory technique used to visualize individual neurons in brain tissue. It involves applying a chemical that selectively coats a small number of neurons, coloring them darkly without affecting surrounding cells. This allows scientists to see the detailed shapes and connections of neurons under a microscope, providing insight into the brain's structure and how neurons connect and communicate. The Golgi stain has been fundamental in understanding the complex wiring of the nervous system and the morphology of neurons.
