Demonstration of Deep Nuclei of the Insula by Fiber Dissection
1Tokat Devlet Hastanesi, Beyin ve Sinir Cerrahisi Kliniği, Tokat, Türkiye The insula is the invagination of the brain deep in the sylvian fissure and is surrounded by three sulci (anterior, superior and inferior). The anterobasal part of the insula is called limen insula. The insula is a region associated with important functional neuroanatomical structures. In this region, there are important white matter pathways such as extreme, external and internal capsule, as well as important nuclear structures such as caudate nucleus, putamen, globus pallidus, claustrum and thalamus. The claustrum is a gray matter structure located between the internal and external capsules and has been reported to be present in all mammals examined. The putamen and globus pallidus (lentiform nuclei) are located at the medial of the external capsule. Lateral to medial white matter dissection shows the extreme capsule, claustrum, external capsule, putamen, globus pallidus, internal capsule and caudate nucleus, as well as the nucleus accumbens and substantia innominata, respectively.
