The material stained blue in the image corresponds to which neural structure?

Explanation:
The blue material is myelin. Luxol fast blue binds to the lipid-rich sheaths that wrap around axons, staining them blue. In neurohistology slides stained this way (often with a Cresyl Violet counterstain), white matter—rich in myelinated axons—appears blue, while neuron cell bodies and nuclei stain a different color. So the blue structure you’re seeing corresponds to the myelin sheath surrounding axons.
