1843-1926. Italian cell biologist who with Santiago Ramon y Cajal produced the first detailed knowledge of the fine structure of the nervous system. Golgi's use of silver salts in staining cells proved so effective in showing up the components and fine processes of nerve cells that even the synapses - tiny gaps between the cells - were visible. The Golgi body, a series of flattened membranous cavities found in the cytoplasm of cells, was first described by him in 1898. Golgi and Ramon y Cajal shared the 1906 Nobel Prize for Medicine.
