What is the cingulum in the brain?
The cingulum bundle (CB) is a critical white matter fiber tract in the brain, which forms connections between the frontal lobe, parietal lobe and temporal lobe. In non-human primates, the CB is actually divided into distinct subcomponents on the basis of corticocortical connections.
What is the function of the cingulate?
A component of the limbic system, it is involved in processing emotions and behavior regulation. It also helps to regulate autonomic motor function. Furthermore, the cingulate cortex has many bilateral connections with the frontal, temporal, and occipital cortex of both hemispheres of the brain.
What are the characteristics of cingulum?
The cingulum bundle is a prominent white matter tract that interconnects frontal, parietal, and medial temporal sites, while also linking subcortical nuclei to the cingulate gyrus. Despite its apparent continuity, the cingulum’s composition continually changes as fibres join and leave the bundle.
What is the parahippocampal gyrus?
The parahippocampal gyrus is a cortical region in the medial temporal lobe that surrounds the hippocampus and plays an important role in both spatial memory (Squire, L. R. and Zola-Morgan, S., 1991) and navigation (Aguirre, G. K. et al., 1996; Maguire, E. A. et al., 1996).
Is the cingulate gyrus GREY matter?
The volume of the gray matter in the anterior cingulate gyrus was found to be lower in people with schizophrenia. Healthy females have larger rostral anterior cingulate gyrus than males, this sex difference in size is absent in people with schizophrenia.
Where does ACC project to?
3.1. ACC neurons project to the medial shell of the NAc and rostral VTA. A primary source of output from the ACC occurs via the pyramidal neurons, which are glutamatergic neurons that specifically express the CaMKIIα promoter.
What is parahippocampal gyrus?
Is cingulate gyrus part of basal ganglia?
Basal Ganglia. The basal ganglia are a collection of nuclei found on both sides of the thalamus, outside and above the limbic system, but below the cingulate gyrus and within the temporal lobes.
What does the parahippocampal region do?
The parahippocampal place area (PPA) is a region in the human collateral sulcus that responds more strongly to visual scenes (e.g. images of landscapes or cityscapes) than to other visual stimuli.
