F G Wouterlood et al.
Journal of neuroscience methods, 7(4), 295-308 (1983-04-01)
A procedure is described by which the solid silver chromate precipitate present in Golgi-impregnated neurons is reduced by a photographic developer into metallic silver grains or particles. The remaining silver chromate is subsequently removed, and the fine structure and synaptic
N Fernandez et al.
Journal of the history of the neurosciences, 10(1), 19-26 (2001-07-12)
Knowledge of cerebral structure and function in its modern form can be traced to the neurone doctrine based largely on the work of Santiago Ramón y Cajal [1852-1934] and his lifelong exploitation of the Golgi method. Cajal openly acknowledged his
A Angulo et al.
The journal of histochemistry and cytochemistry : official journal of the Histochemistry Society, 42(3), 393-403 (1994-03-01)
We examined the role of chromium reduction in the Golgi-Colonnier method, correlating the quality of neuronal impregnation with the levels of hexavalent (CrVI) and trivalent (CrIII) chromium in the tissue and in the chromation fluid (CF). The concentrations of both

Stain technology, 61(6), 337-352 (1986-11-01)
Deterioration of Golgi impregnation begins immediately after impregnated tissue blocks are sectioned with the Vibratome. The first signs of deterioration are fading of delicate impregnated processes, the disruption and fragmentation of dendrites, and, eventually, fading of entire neurons. These changes
F G Wouterlood
Microscopy research and technique, 23(4), 275-288 (1992-12-01)
Direct electron microscopy of nervous tissue stained with the Golgi impregnation method is unsatisfactory because the cytoplasm of the cell bodies and processes of the impregnated neurons are completely filled with a compact precipitate of electron dense silver chromate. This
