Neuronal damage can be assessed using various staining techniques. Hematoxylin and eosin (H&E) staining is commonly used to identify general tissue architecture and pathology. Immunohistochemistry (IHC) for markers such as NeuN (neuronal nuclei) and MAP2 (microtubule-associated protein 2) helps in identifying neuronal loss and dendritic damage. Silver staining can highlight axonal injury and degenerating neurons.
