Cytoarchitecture (Greek κύτος= "cell" + αρχιτεκτονική= "architecture"), also known as cytoarchitectonics, is the study of the cellular composition of the body's tissues under the microscope. Applied particularly to the study of the central nervous system, cytoarchitectonics is one of the ways to parse the brain, by obtaining sections of the brain and staining them with chemical agents that reveal how neurons are "stacked" into layers.
