The legacy of Camillo Golgi for modern concepts of brain organization.

The experimental advance made by Camillo Golgi's 'black reaction' has been universally recognized as the start of the modern revolution in the study of the nervous system. By contrast, his concepts of nervous organization, particularly his support for the idea of a 'nervous reticulum', have been universally rejected. The premise of the present paper is that ideas of a biologist of this stature deserve re-examination. Golgi's arguments for considering the holistic function of the brain seem to come from his experience as a physician, and presage the views of the gestaltists and, more recently, the conceptual underpinnings of artificial neural networks. His interest in the possible nutritional roles of neuronal dendrites can be seen to anticipate current investigations, at the cellular level, of the metabolic basis of brain imaging. These and other currents in Golgi's thought deserve further study.
