Circular Insular Furrow [S. Circularis Insulae, Pna; S. circularis (Reili), Bna; S. circularis, Jna; Syn. Reileva Borozd]

Circular insular sulcus (S. Circularis Insulae, S. Circularis Reili, S. Circularis Jna) is a cerebral sulcus that separates the insula from the frontal, parietal and temporal lobes of the brain. It is located on the superolateral surface of the cerebral hemisphere and is one of the largest grooves in this area.

The sulcus of the insula Circular is located on the upper edge of the cerebral hemisphere, towards the anterior part of the cortex. It begins at the posterior end of the insula and runs across its entire anterior edge, separating it from the frontal lobe. It then rises up and continues on the lateral surface of the brain, separating the insula from the parietal lobe. Finally, the sulcus descends and ends at the temporal lobe, separating it from the insula. Thus, it forms a circular shape, which gives it the name “Circular insula fissure.”

The function of the sulci of the circular insula is to divide the cerebral cortex into functional areas that are responsible for various functions such as vision, hearing, speech, memory and thinking. The insula plays an important role in sensory processing and motor coordination.

In addition, the sulcus of the circular insula is also involved in the regulation of blood pressure and heart rate. In particular, it is associated with the centers of the hypothalamus, which are responsible for the regulation of these functions.

Overall, the insular sulcus is an important brain structure that plays a key role in the functioning of the cerebral cortex and the regulation of various body functions.

Fissure Insular Circular - B., located on the superolateral surface of the brain - from the anterior surface of the 3rd ventricle to the insular lobe of the brain (8th pair). At the base of the cerebrum, the fissure is located in front of the insular nucleus, which determines its name. Posterior furrows
