Why is staining used in histology?

Staining is used to highlight important features of the tissue as well as to enhance the tissue contrast. Hematoxylin is a basic dye that is commonly used in this process and stains the nuclei giving it a bluish color while eosin (another stain dye used in histology) stains the cell’s nucleus giving it a pinkish stain.

When was silver staining used in histology?

This historic technique allowed Santiago Ramón y Cajal (1852–1934) to interpret the structure of the central nervous system. There are also a range of other silver staining techniques (see silver staining reticular fibres). Developed in 1950 by an American histologist George Gömöri (1904–1957).

What is Golgi stain in psychology?

There are also a range of other silver staining techniques (see silver staining reticular fibres).
