The cingulate cortex includes the entire cingulate gyrus, which lies immediately above the corpus callosum, and the continuation of this in the cingulate sulcus. The cingulate cortex is usually considered part of the limbic lobe .
The cingulate gyrus plays a key role in the limbic system's emotion formation and processing. The cingulate cortex is separated into an anterior and a posterior region, which corresponds to areas 24, 32, 33 (anterior) and 23 (posterior) of the Brodmann areas .
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 ...
The posterior cingulate cortex is considered a paralimbic cortical structure, consisting of Brodmann areas 23 and 31. As part of the paralimbic cortex, it has fewer than six layers, placing its cell architecture in between the six-layered neocortex and the more primitive allocortex of core limbic structures. It has also been associated with the ...
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 ...
The Brodmann area 32, also known in the human brain as the dorsal anterior cingulate area 32, refers to a subdivision of the cytoarchitecturally defined cingulate cortex. In the human it forms an outer arc around the anterior cingulate gyrus .
This area is also known as ventral posterior cingulate area 23. It is a subdivision of the cytoarchitecturally defined cingulate region of cerebral cortex. In the human it occupies most of the posterior cingulate gyrus adjacent to the corpus callosum. At the caudal extreme it is bounded approximately by the parieto-occipital sulcus.
Fibres arise from the primary motor cortex (about 30%), supplementary motor area and the premotor cortex (together also about 30%), and the somatosensory cortex, parietal lobe, and cingulate gyrus supplies the rest. [2] The cells have their bodies in the cerebral cortex, and the axons form the bulk of the pyramidal tracts. [4]
