Study Notes
Brain Mystery
- The structure of the brain is a mystery, and this mystery reflects the larger mystery of the universe
- Camillo Golgi developed a tissue-staining technique in 1873, to make nerve cells clearer under a microscope, using silver nitrate
Golgi's Technique
- Golgi wanted to clarify nerve cell structures and make them visible under a microscope
- Golgi's technique involved staining nerve cells with silver nitrate
- Cajal improved Golgi's technique
- Despite evidence, Golgi defended his reticular theory, and argued with Cajal on the structure of the nervous system
Cajal's Contributions
- Cajal used pen and ink drawings to reproduce the structures of the brain and nervous system
- Cajal's drawings transmitted his observations to the scientific world
- Cajal's work was almost photographic in its precision
- Cajal was awarded a Nobel Prize in 1906 (alongside Golgi)
