Secondary Education From 1888 on, Ramón y Cajal worked on the study of the connections of the nerve cells, for which he developed his own staining methods, exclusive for neurons and nerves, an improvement on those created by Camillo Golgi. Thanks to this, he managed to demonstrate that the neuron is the fundamental constituent of nerve tissue... Santiago Ramón y Cajal Diagram of a neuron drawn by Santiago Ramón y Cajal. He also studied the structure of the brain and the cerebellum, the spinal cord, the medulla oblongata and various sense centres of the organism, such as the retina. His world fame increased when, in 1906, he won the Nobel Prize for Physiology or Medicine for his discoveries about the structure of the nervous system and the role of the neuron, a prize which he shared with C.
