The Brodmann Areas are important numbered divisions of the cerebral cortex into regions based on their neuronal arrangement and connections. The concept of Brodmann areas was introduced by neurologist Korbinian Brodmann in the early 20th century (Brodmann, 1909). Brodmann's work has impacted the understanding of the functional organization of the cortex and remains influential in neuroscience research.
 

Brodmann's classification was based on his observations of differences in the cellular organization of the cortex across various mammalian species, including humans. He identified 43 numbered areas in the human brain by examining the cellular organization, cell types, and layer thickness (Kurth et all, 2010). Some refinements have been made since Brodmann's initial classification, and many identified areas retain their original numbering.
