Santiago Ramón y Cajal

Santiago Ramón y Cajal was a Spanish neuroscientist, often regarded as the father of modern neuroscience. In the late 19th and early 20th centuries, he used innovative staining techniques to visualize neurons, revealing their structure and connectivity. His work demonstrated that the nervous system is made up of individual cells, rather than being a continuous network, a pioneering idea known as the "Neuron Doctrine." Cajal's insights laid the foundation for our understanding of the brain and earned him the Nobel Prize in Physiology or Medicine in 1906, alongside Camillo Golgi. His research continues to influence neuroscience today.
