Study Notes
Brain Structure and Mystery
- The structure of the brain is a mystery, which reflects the mystery of the universe
- Camillo Golgi, an Italian doctor, invented a tissue staining technique to study the nervous system
- Golgi (1843-1926) wanted to improve the clarity of nerve cells under the microscope
- In 1873, Golgi discovered a method to make nerve cells appear black with silver nitrate
- Santiago Ramon y Cajal improved Golgi's method
- Despite evidence to the contrary, Golgi clung to the reticular theory
- Cajal's detailed drawings of the brain's structure were a powerful tool for scientific observations
