Brodmann area 23
Brodmann area 23 (BA23), also known as the posterior cingulate cortex, is a region of the brain that is part of the limbic system. It is named after its discoverer, Korbinian Brodmann, a German neurologist.
Pronunciation
Brodmann area 23 is pronounced as "Brod-man area twenty-three".
Etymology
The term "Brodmann area 23" is named after Korbinian Brodmann, who was a German neurologist and known for his definition of the cerebral cortex into 52 distinct regions from their cytoarchitectonic characteristics.
Function
The Brodmann area 23, or the posterior cingulate cortex, is involved in various cognitive functions, including attention and memory. It is also associated with the default mode network, a network of interacting brain regions known to have activity highly correlated with each other and distinct from other networks in the brain.
