    Purpose:

    • To present a modified Golgi silver impregnation technique.
    • To enable the clear demonstration of apical dendrites and spines.
    • To improve the analysis of neuronal morphology in archival tissue samples.

    Summary:

    • A modified Golgi silver method is described for formalin-fixed neural tissues.
    • The protocol involves specific incubation steps with potassium bichromate and silver nitrate solutions.
