insular region
The term
insular region originally referred to a cytoarchitecturally defined portion of the
cerebral cortex that occupies all of the
insula and immediately adjacent portions of surrounding
frontal lobe and
temporal lobe (
Brodmann-1909 ). Subsequently it has come to refer to one of three components of the olfactocentric division of the
paralimbic regions( Mesulam-1984 ). The other components are the orbitofrontal region and the temporopolar region.
The three regions surround and radiate from the
piriform cortex (
allocortex ) into the corresponding
insula,
orbital gyri and polar portion of the
superior temporal gyrus. Each is subdivided into an agranular (
periallocortex ) belt, a dysgranular (
proisocortex ) belt and a granular (
true isocortex ) belt, which is continous with granular areas of surrounding
neocortex: the
primary somatosensory cortex, the
secondary somatosensory cortex and the
retroinsular area.
The corresponding subdivisions of the
insular region are the agranular
insula, the
dysgranular insula, and the
granular insula ( Mesulam-1984 ).
Also known as: Regio insularis, insular region, insula region
