title: Evolution of the silver and gold stains in neurohistology.
abstract: Scientific investigations depend on the reliability of the observations that can be made. This reliability is determined in part by the understanding of the techniques and technology used to make the observations. The limitations and the strengths of the methodology and the equipment used must be evaluated thoroughly. The extent to which this is and has been the case for the use of the metal based stains in neuroscience is the subject of this paper. I evaluate the metallic stains used for neuroscience from several perspectives. I review briefly the state of neurohistology prior to its "golden years," 1870-1910. Then I trace the development of the silver based stains used for neurohistology. I wanted to discuss the reasoning used by the originators of the silver based techniques in developing their specific procedures, but discovered that while procedures may be published, the methods and ideas used to arrive at the final procedures are not usually described in published work.
