Nissl bodies can be demonstrated by a method of selective staining developed by Nissl (Nissl staining), using an aniline stain to label extranuclear RNA granules. RNA stains blue with this method due to its basophilic (lat. "base-loving") properties.
Nissl bodies show changes under various physiological conditions and in pathological conditions they may dissolve and disappear (karyolysis).
