Sagittal MRI slice with highlighting indicating location of the cingulate cortex. Coronal section of brain. Cingulate cortex is shown in yellow. The cingulate cortex is a part of the brain situated in the medial aspect of the cerebral cortex.
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.
In cingulate or subfalcine herniation, the most common type, the innermost part of the frontal lobe is scraped under part of the falx cerebri, the dura mater at the top of the head between the two hemispheres of the brain. [8] [13] Cingulate herniation can be caused when one hemisphere swells and pushes the cingulate gyrus by the falx cerebri. [7]
The posterior cingulate cortex (PCC) is the caudal part of the cingulate cortex, located posterior to the anterior cingulate cortex. This is the upper part of the "limbic lobe". The cingulate cortex is made up of an area around the midline of the brain. Surrounding areas include the retrosplenial cortex and the precuneus.
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 precuneus is bounded in front by the marginal branch of the cingulate sulcus, at the rear by the parieto-occipital sulcus, and underneath by the subparietal sulcus. It is involved with episodic memory, visuospatial processing, reflections upon self, and aspects of consciousness. The location of the precuneus makes it difficult to study.
The cingulate sulcus is a sulcus (brain fold) on the cingulate cortex in the medial wall of the cerebral cortex. The frontal and parietal lobes are separated from the cingulate gyrus by the cingulate sulcus.
red:Brodmann area 41, green:Brodmann area 42, note 1: BA41 is bounded medially by Brodmann area 52 and laterally by BA42, note 2: pSTG is posterior part of the superior temporal gyrus In human brain anatomy, an operculum (Latin, meaning "little lid") ( pl. : opercula ), may refer to the frontal, temporal, or parietal operculum, which together ...
