The middle segment of the cingulum contains connections with premotor and motor cortical areas. Another place of importance that explains the cingulum and its relation to mild cognitive impairment is the fact that the cingulum connects to the hippocampus. The cingulum takes memory information and integrates this to other parts of the 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]
This is in contrast to other structures in the limbic system, such as the amygdala, which are thought to respond disproportionately to negative stimuli, or the left frontal pole, which activated only in response to positive stimuli. These results support the hypothesis that the posterior cingulate cortex mediates interactions between emotion ...
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.
Bilateral cingulotomy targets the anterior cingulate cortex, which is a part of the limbic system. This system is responsible for the integration of feelings and emotion in the human cortex. It consists of the cingulate gyrus, parahippocampal gyrus, amygdala, and the hippocampal formation. [8]
The parahippocampal gyrus (or hippocampal gyrus [1]) is a grey matter cortical region of the brain that surrounds the hippocampus and is part of the limbic system. The region plays an important role in memory encoding and retrieval. It has been involved in some cases of hippocampal sclerosis. [2] Asymmetry has been observed in schizophrenia. [3]
(The red color shows the posterior cingulate and its connections.). The precuneus is located on the inside between the two cerebral hemispheres in the rear region between the somatosensory cortex and forward of the cuneus (which contains the visual cortex).
Behavioral neuroscience in relation to systems neuroscience focuses on representational dissimilarity matrices (RDMs), which categorizes brain activity patterns and compares them across different conditions, such as the dissimilar level of brain activity observing an animal in comparison to an inanimate object.
