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.
Remains of the top floors of an insula near the Capitolium and the Insula dell'Ara Coeli in Rome. In Roman architecture, an insula (Latin for "island", pl.: insulae) was one of two things: either a kind of apartment building, or a city block. [1] [2] [3] This article deals with the former definition, that of a type of apartment building.
Normally, the insular opercula begin to develop between the 20th and the 22nd weeks of pregnancy. At weeks 14 to 16 of fetal development, the insula begins to invaginate from the surface of the immature cerebrum of the brain, until at full term, the opercula completely cover the insula. [4] This process is called opercularization. [5]
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 ...
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]
Insula is the Latin word for "island" and may refer to: Insula (Roman city) , a block in a Roman city plan surrounded by four streets Insula (building) , a kind of apartment building in ancient Rome that provided housing for all but the elite
The limen insulae forms the junction point between anterior and posterior stem of the lateral sulcus.It is the lateral most limit of the anterior perforated substance and the starting point of the insular cortex.
The insula (or insular cortex), is the main neural structure involved in the emotion of disgust. [ 6 ] [ 27 ] [ 33 ] The insula has been shown by several studies to be the main neural correlate of the feeling of disgust both in humans and in macaque monkeys.
