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 ...
Its connections have been summarized as "it seems not to be interconnected with ‘downstream’ areas in the way that other prefrontal areas are. .. it is the only prefrontal region that is predominantly (and possibly exclusively) interconnected with supramodal cortex in the PFC, anterior temporal cortex and cingulate cortex."
The posterior cingulate cortex (Brodmann's area 23) sends projections to dorsolateral prefrontal cortex (Brodmann's area 9), anterior prefrontal cortex (Brodmann's area 10), orbitofrontal cortex (Brodmanns’ area 11), the parahippocampal gyrus, posterior part of the inferior parietal lobule, the presubiculum, the superior temporal sulcus and ...
The medial prefrontal cortex (mPFC) is composed of BA12, BA25, and anterior cingulate cortex: BA32, BA33, BA24. [1] Within that area is the dorsal nexus, which interconnects many parts of the brain. [19] The ventral prefrontal cortex is composed of areas BA11, BA13, and BA14. [1] (Also see the definition of the orbitofrontal cortex.)
In the guenon this area is referred to as area 24 of Brodmann-1905.It includes portions of the cingulate gyrus and the frontal lobe.The cortex is thin; it lacks the internal granular layer (IV) so that the densely distributed, plump pyramidal cells of sublayer 3b of the external pyramidal layer (III) merge with similar cells of the internal pyramidal layer (V); the multiform layer (VI) is very ...
In the guenon, Brodmann area 32 is a subdivision of the cytoarchitecturally defined cingulate region of cerebral cortex.This area was named 25 in Brodmann-1905 and labeled 25 in a figure contributed by Brodmann in Mauss-1908.
In neuroscience, the default mode network (DMN), also known as the default network, default state network, or anatomically the medial frontoparietal network (M-FPN), is a large-scale brain network primarily composed of the dorsal medial prefrontal cortex, posterior cingulate cortex, precuneus and angular gyrus.
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).
