area v23ab
Acronym: v23ab
The term area v23ab refers to a part of posterior cingulate cortex located in the posterior cingulate gyrus and isthmus of the cingulate gyrus. It is separated from the splenium of the corpus callosum by retrosplenial cortex and bounded caudally by area POS1, dorsally by area 7m and area 31pd, and rostrally by area 31pv and area d23ab. It is considered equivalent to the sum of area v23a and area v23b of Vogt-2009. Defined in the human by multiple criteria, it is somewhat fMRI-activated in a STORY task and deactivated in RELATIONAL and FACES tasks. Other authors have referred to overlapping parts of the same topological area as 23a, 23b, and v23 ( Glasser-2016 ).
