Gyrus longus insulae

From WikiMD's Wellness Encyclopedia

Gyrus longus insulae is a structure in the human brain located within the insula, which is part of the cerebral cortex. The insula itself is a small region situated deep within the lateral sulcus, which separates the temporal lobe from the frontal lobe and parietal lobe. The gyrus longus insulae is one of the two main gyri of the insula, the other being the gyrus brevis insulae.

Structure[edit | edit source]

The gyrus longus insulae runs along the long axis of the insula, extending from the apex near the limen insulae to the anterior perforated substance. It is typically longer and less curved than the gyrus brevis insulae. The surface of the gyrus longus insulae is divided by shallow sulci into several short gyral segments.

Function[edit | edit source]

The exact functions of the gyrus longus insulae are not fully understood, but the insula as a whole is known to be involved in diverse functions including perception, motor control, self-awareness, cognitive functioning, and interpersonal experience. More specifically, the insula has been implicated in functions ranging from consciousness to the regulation of emotion, as well as the integration of sensory information with visceral responses.

Clinical Significance[edit | edit source]

The gyrus longus insulae, like other parts of the insula, can be involved in various neurological conditions. It may be affected in cases of stroke, epilepsy, and other neurological disorders that impact the insular cortex. Due to its role in processing emotions and bodily sensations, damage to this area can lead to alterations in pain perception, emotional responses, and interoceptive awareness.
