Golgi's method is a silver staining technique that is used to visualize nervous tissue under light microscopy. The method was discovered by Camillo Golgi , an Italian physician and scientist , who published the first picture made with the technique in 1873. [ 1 ]
Camillo Golgi (Italian: [kaˈmillo ˈɡɔldʒi]; 7 July 1843 – 21 January 1926) was an Italian biologist and pathologist known for his works on the central nervous system.He studied medicine at the University of Pavia (where he later spent most of his professional career) between 1860 and 1868 under the tutelage of Cesare Lombroso.
Camillo Golgi perfected silver staining for the study of the nervous system.Although the exact chemical mechanism by which this occurs is unknown, [5] Golgi's method stains a limited number of cells at random in their entirety.
This method was discovered by Italian Camillo Golgi, by using a reaction between silver nitrate and potassium dichromate, thus precipitating silver chromate in some cells (see Golgi's method). Argyrophilic cells reduce silver solution to metallic silver after being exposed to the stain that contains a reductant.
Dendritic spines were first noted by Ramón y Cajal in 1888 by using Golgi's method. Ramón y Cajal was also the first person to propose the physiological role of increasing the receptive surface area of the neuron. The greater the pyramidal cell's surface area, the greater the neuron's ability to process and integrate large amounts of information.
Waldeyer learned Spanish in order to absorb Cajal's detailed studies using Golgi's method and became his friend, mentor and promoter in the German-dominated field of microscopic anatomy. The theory was published in a series of papers in the main medical journal of Germany, Deutsche Medizinische Wochenschrift , which became extremely influential.
Golgi apparatus (also called the Golgi body, Golgi complex, or dictyosome), an organelle in a eukaryotic cell; Golgi tendon organ, a proprioceptive sensory receptor organ; Golgi's method or Golgi stain, a nervous tissue staining technique; Golgi alpha-mannosidase II, an enzyme; Golgi cell, a type of interneuron found in the cerebellum
Rather than using the traditional method of presenting the cells treated with Golgi techniques as opaque blobs on a neutral background, he took the unconventional step of including illustrations of the textures, dimensions, and surfaces of the cells in his studies, which he believed allowed for a richer understanding of the microscopist’s ...
