Ramon y Cajal

Santiago Ramón y Cajal was a pioneering Spanish neuroscientist who, in the late 19th and early 20th centuries, made groundbreaking discoveries about the structure of the nervous system. Using advanced staining techniques, he was able to visualize individual neurons, proving that the brain is made up of discrete cells rather than a continuous network. His work laid the foundation for modern neuroscience, enhancing our understanding of how nerve cells communicate and how the brain functions. Cajal’s insights earned him the Nobel Prize in Physiology or Medicine in 1906, and he is celebrated as one of the great founders of neurobiology.
