The cingulum is described from various brain images as a C-shaped structure within the brain that wraps around the frontal lobe to the temporal lobe right above the corpus callosum. It is located beneath the cingulate gyrus within the medial surface of the brain therefore encircling the entire brain.
Cingulum means "belt" in Latin. [25] The name was likely chosen because this cortex, in great part, surrounds the corpus callosum. The cingulate cortex is a part of the "grand lobe limbique" of Broca (1878) that consisted of a superior cingulate part (supracallosal) and an inferior hippocampic part (infracallosal). [26]
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 assigning appropriate control to other areas in the brain.
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.
Association fibers are axons (nerve fibers) that connect cortical areas within the same cerebral hemisphere. [1]In human neuroanatomy, axons within the brain, can be categorized on the basis of their course and connections as association fibers, projection fibers, and commissural fibers. [1]
The cingulum forms from this lingual lobe of development. [12] The majority of a lingual surface's cervical third is made up of the cingulum. [13] On lower incisors, a cingulum usually is poorly developed or absent. Maxillary canines have a large, well-developed cingulum, [13] whereas the cingulum of mandibular canines is smoother and rounded. [14]
