It can also refer to the occipital operculum, part of the occipital lobe. The insular lobe is a portion of the cerebral cortex that has invaginated to lie deep within the lateral sulcus . It sits like an island (the meaning of insular ) almost surrounded by the groove of the circular sulcus and covered over and obscured by the insular opercula.
The primary gustatory cortex (GC) is a brain structure responsible for the perception of taste.It consists of two substructures: the anterior insula on the insular lobe and the frontal operculum on the inferior frontal gyrus of the frontal lobe. [1]
The insular cortex (also insula and insular lobe) is a portion of the cerebral cortex folded deep within the lateral sulcus (the fissure separating the temporal lobe from the parietal and frontal lobes) within each hemisphere of the mammalian brain.
Frontal lobe (red) of left cerebral hemisphere. The frontal lobe is the largest lobe of the brain and makes up about a third of the surface area of each hemisphere. [3] On the lateral surface of each hemisphere, the central sulcus separates the frontal lobe from the parietal lobe.
The left opercular part of the inferior frontal gyrus is a part of the articulatory network involved in motor syllable programs. The articulatory network also contains the premotor cortex, and the anterior insula.
Changes in the structure of gyri in the cerebral cortex are associated with various diseases and disorders. Pachygyria , lissencephaly , and polymicrogyria are all the results of abnormal cell migration associated with a disorganized cellular architecture, failure to form six layers of cortical neurons (a four-layer cortex is common), and ...
Operculum (animal), a structure resembling a lid or a small door that opens and closes; Operculum (bird), a structure which covers the nares of some birds; Operculum (bryozoa), a lid on the orifice of some bryozoans; Operculum (fish), a flap covering the gills of bony fish; Operculum (gastropod), a sort of trapdoor used to close the aperture of ...
The planum temporale is a highly lateralized brain structure involved with language and with music. Although the planum temporale is found to have an asymmetry in the normal population, having a leftward bias in right-handed individuals, people who possess absolute pitch have an increased leftward asymmetry of the planum temporale.
