The Black Stain That Changed Neuroscience

The video explores the history of neuroscience, focusing on the discovery of neurons. It highlights the contributions of Camila Golgi and Santiago Ramón y Cajal, who used innovative staining techniques to visualize brain cells. Golgi's black reaction was a breakthrough, but he adhered to the reticular theory, which Cajal challenged. Cajal's observations led to the neuron doctrine, establishing that the nervous system is composed of discrete cells. Their work earned them a joint Nobel Prize, and their techniques continue to influence modern neuroscience.
