The insular cortex is divided by the central sulcus of the insula, into two parts: the anterior insula and the posterior insula in which more than a dozen field areas have been identified. The cortical area overlying the insula toward the lateral surface of the brain is the operculum (meaning lid ).
Area 15 is located in the part of the insula nearest the temporal lobe and part of the anterior temporal lobe facing the insula. [1] It is buried in the Sylvian Fissure and thus not visible on the surface of the brain without dissection.
The insular cortex is divided into two parts: the larger anterior insula and the smaller posterior insula in which more than a dozen field areas have been identified. The cortical area overlying the insula toward the lateral surface of the brain is the operculum (meaning lid). The opercula are formed from parts of the enclosing frontal ...
In human brain anatomy, an operculum (Latin, meaning "little lid") (pl.: opercula), may refer to the frontal, temporal, or parietal operculum, which together cover the insula as the opercula of insula. [1] It can also refer to the occipital operculum, part of the occipital lobe.
The claustrum is a small bilateral gray matter structure (comprising roughly 0.25% of the cerebral cortex) located deep to the insular cortex and extreme capsule, and superficial to the external capsule and basal ganglia.
The lateral sulcus (or lateral fissure, also called Sylvian fissure, after Franciscus Sylvius) is the most prominent sulcus of each cerebral hemisphere in the human brain. The lateral sulcus is a deep fissure in each hemisphere that separates the frontal and parietal lobes from the temporal lobe. The insular cortex lies deep within the lateral ...
A Brodmann area is a region of the cerebral cortex, in the human or other primate brain, defined by its cytoarchitecture, or histological structure and organization of cells.
This region is extremely rich in serotonin transporters and is considered as a governor for a vast network involving areas like hypothalamus and brain stem, which influences changes in appetite and sleep; the amygdala and insula, which affect the mood and anxiety; the hippocampus, which plays an important role in memory formation; and some parts of the frontal cortex responsible for self ...
