Which stain would you use to study neural components such as dendrites and axons?

• A. Bielschowsky's Silver Technique
• B. Gordon & Sweet's
• C. Gomori Burtner
• D. Gomori's Aldehyde Fuchsin

Answer: (A)

Studying neural components like dendrites and axons requires a stain that highlights neurites by depositing silver on the argyrophilic neurofilaments in neurons.

Bielschowsky's Silver Technique does exactly that: it impregnates neural fibers with silver so axons and dendrites stand out as dark structures against a lighter background. This makes fine neuronal processes visible and is a classic method in neuropathology for examining nerve fibers and related changes, including degenerative processes.

The other stains are used for different tissue components rather than neuronal processes. They tend to emphasize connective tissue elements such as reticulin or elastic fibers, not the delicate neural processes, so they don’t visualize dendrites and axons as effectively as Bielschowsky’s method.
