Study Notes
Santiago Ramón y Cajal
- Nobel Prize-winning neuroscientist
- Pioneered the use of microscopes to study the nervous system
- First to understand that the nervous system is composed of independent communicating cells
- Born in northern Spain
Milestones
- Turning Point: Observed Golgi's obscure tissue-staining method in 1887, realizing its potential for research
- Technological Feat: Modified Golgi's stain in 1888, enhancing its ability to illuminate brain tissue
- Discredits Theory: In 1888, demonstrated that nerve cells are separate units, not continuous
- Writes Magnum Opus: Published the first volume of his major book on the structure of the nervous system in 1899
Microscopes and Staining
- As a doctor, Cajal initially used microscopes to study muscle tissue at increasing magnification
- He shifted to understanding the nervous system, using histology as the focus.
- Improvements in microscope optical lenses and tissue stains allowed for more detailed observations of individual nerve cells
- Early 1800s microscopes had limitations in resolution and magnification, but these limitations were overcome in Cajal's time
Prize Winner
- Jointly won the Nobel Prize in 1906 with Camillo Golgi for their work on the structure of the nervous system
- Developed Golgi's tissue-staining technique further, creating numerous illustrations of the human brain and nervous system
