area a24
Acronym:
a24
The term area a24 refers to a narrow strip of anterior cingulate cortex located adjacent to the genu of the corpus callosum and rostrum of the corpus callosum ( Glasser-2016; Vogt-2012 ). In the human it is bounded dorsocaudally by area p24, dorsally by area d32 and area 9m, rostroventrally by area p32, rostroventrally by area s32 and ventrocaudally by area 25 ( Glasser-2016 ). Defined in the human by multiple criteria, it is fMRI-deactivated in LANGUAGE STORY, THEORY OF MIND and FACES tasks. It has two parts, a more caudal area 24a in the rostral wall of the callosal sulcus and area 24b, which lies parallel to 24a on the surface of the subcallosal gyrus and anterior cingulate gyrus ( Vogt-2012 ). In another parcellation scheme, it is divided into ventral and dorsal parts, s24ab and p24ab respectively ( Vogt-2013 ).
In the macaque it has ventral and dorsal parts area 24a and area 24b respectively.
The rat and mouse have an area 24a and area 24b equivalent to the macaque areas, except that they are located in the anterior cingulate area posterior to area 32o and dorsal to the genu of the corpus callosum ( Vogt-2013 ).
