    Main Methods:

    • Utilized an alcohol solution of uranyl acetate at pH 5.0-6.0.
    • Employed unosmicated material for enhanced structural preservation.
    • Performed various procedures to establish chemical characteristics of stained structures.

    Main Results:

    • Successfully demonstrated synaptic densities in the rat CNS.
    • The uranyl acetate staining method proved effective for visualizing these structures.
    • Initial characterization of the chemical properties of the stained synaptic components was achieved.

    Conclusions:

    • The described method provides a reliable way to visualize synaptic densities.
    • This technique aids in the chemical characterization of synapses.
    • Offers a new tool for neuroscience research on synaptic structure and function.
