History of Medicine

Even though the origins of neuroscience can be traced back to the ancient Greeks, it remained a speculative science until the imaging of the neurons. The person who transformed the study of nerves to an experimental and observational science was Spanish physician Santiago Ramón y Cajal. Cajal’s images and drawings made such a profound contribution to the field of neuroscience that he is considered the Father of Neuroscience. Cajal (1852-1935) created nearly 3000 drawings of the nervous system, detailing its architecture, and unraveling the mysteries of neuroanatomy. Through his elaborate drawings of the nervous system, he showed that the brain is made up of individual cells called neurons. Until Cajal’s drawings, the common view was that the nervous system was a spider web-like structure of cells that behaved like a single unit.
