Brodmann area
While the ventromedial prefrontal cortex does not have a universally agreed on demarcation, in most sources, it is equivalent to the ventromedial reward network of Öngür and Price. This network includes Brodmann area 10, Brodmann area 14, Brodmann area 25, and Brodmann area 32, as well as portions of Brodmann area 11, Brodmann area 12, and Brodmann area 13. However, not all sources agree on the boundaries of the area. Different researchers use the term "ventromedial prefrontal cortex" differently. Sometimes, the term is saved for the area above the medial orbitofrontal cortex, while at other times, 'ventromedial prefrontal cortex' is used to describe a broad area in the lower (ventral) central (medial) region of the prefrontal cortex, of which the medial orbitofrontal cortex constitutes the lowermost part. This latter, broader area, corresponds to the area damaged in patients with decision-making impairments investigated by António Damásio and colleagues (see diagram, and below).
