The anterior cingulate cortex can be divided anatomically based on cognitive , and emotional components. [5] The dorsal part of the ACC is connected with the prefrontal cortex and parietal cortex , as well as the motor system and the frontal eye fields , [ 6 ] making it a central station for processing top-down and bottom-up stimuli and ...
The ventral anterior cingulate (Brodmann's area 24) sends projections to the anterior insular cortex, premotor cortex (Brodmann's area 6), Brodmann's area 8, the perirhinal area, the orbitofrontal cortex (Brodmann's area 12), the laterobasal nucleus of amygdala, and the rostral part of the inferior parietal lobule.

The salience network is theorized to mediate switching between the default mode network and central executive network. [1] [2]The salience network (SN), also known anatomically as the midcingulo-insular network (M-CIN) or ventral attention network, is a large scale network of the human brain that is primarily composed of the anterior insula (AI) and dorsal anterior cingulate cortex (dACC).
In the human this area is known as ventral anterior cingulate area 24, and it refers to a subdivision of the cytoarchitecturally defined cingulate cortex region of cerebral cortex (area cingularis anterior ventralis). It occupies most of the anterior cingulate gyrus in an arc around the genu of the corpus callosum.
It is located beneath the cingulate gyrus within the medial surface of the brain therefore encircling the entire brain. There are two primary parts of the cingulate cortex: the posterior cingulate cortex and the anterior cingulate cortex. The anterior is linked to emotion, especially apathy and depression. Here function and structure changes ...
Simplified diagram of frontal cortex to striatum to thalamus pathways. There are five defined frontostriatal circuits: motor and oculomotor circuits originating in the frontal eye fields are involved in motor functions; while dorsolateral prefrontal, orbital frontal, and anterior cingulate circuits are involved in executive functions, social behavior and motivational states. [2]
An anterior cingulate circuit that involves projections from the ACC to the ventral striatum, through the rostrolateral GPi/VP/rostrodorsal SNr, which returns via the posteromedial medialis dorsalis. A problem identified with the current anatomy of the circuit is that the time delay between the direct and indirect pathways should result in this ...
Sensorimotor Anterior Region. This occurs around the margin of the cingulate sulcus ( blue in figure) and is connected with sensorimotor areas of the cerebral cortex such as the paracentral lobule, supplementary motor area, premotor cortex, somatosensory area (Brodmann area 2), parietal operculum and insula. fMRI Research upon humans finds a connection with the caudalmost part of ...
