The Nissl staining technique (named for Franz Nissl the neuroscientist and histologist who originated the technique) is commonly used for determining the cytoarchitectonics of neuroanatomical structures, using common agents such as thionine, cresyl violet, or neutral red. These dyes intensely stain "Nissl bodies" (rough endoplasmic reticulum), which are abundant in neurons and reveal specific patterns of cytoarchitecture in the brain.
