What are 2 ways that scientists figured out which functions correspond to which regions in the brain1/10/2024 ![]() ![]() A similar, but more detailed cortical map was published by Constantin von Economo and Georg N. The same Brodmann area number in different species does not necessarily indicate homologous areas. Brodmann published his maps of cortical areas in humans, monkeys, and other species in 1909, along with many other findings and observations regarding the general cell types and laminar organization of the mammalian cortex. History A number of important Brodmann areas have been marked out on this diagram.īrodmann areas were originally defined and numbered by the German anatomist Korbinian Brodmann based on the cytoarchitectural organization of neurons he observed in the cerebral cortex using the Nissl method of cell staining. These regions, or Brodmann areas, correspond with diverse functions including sensation, motor control, and cognition. Brodmann mapped the human brain based on the varied cellular structure across the cortex and identified 52 distinct regions, which he numbered 1 to 52. ![]() The concept was first introduced by the German anatomist Korbinian Brodmann in the early 20th century. A Brodmann area is a region of the cerebral cortex, in the human or other primate brain, defined by its cytoarchitecture, or histological structure and organization of cells. ![]()
