What is an arc fasciculus?

Arcuate fasciculus is a bundle of nerve fibers that combine the time and parietal lobes of the brain, known as the tempooparietal intersection (TPJ), to the frontal lobe. It is also considered to be one of the four components that contain an excellent longitudinal fasculus (SLF). In the medical community, however, there is still a debate on the exact areas of connections in the three lobby. Arcuate fasciculus is a Latin term for a "curved bundle".

Some neurologists believe that the arc fasculus combines the TPJ area called the Wernicke area with the frontal lobe area known as Broca's Area. The Wernicke area is used to recognize or understand speech, while the Broca area is used for speech production. Arcuate fasciculus is therefore considered to be helpful in determining the ability to speak and write.

Broca's Area entered the Medical Lexixics in 1861, when the French neurosurgeon Paul Broca examined the brain of a dead patient who was unable to say a sentence and write his mouseLenka. The patient who was after the only articular sound he was able to express was named "Tan", had this disability, even though he was able to recognize speech. But Tan was without any obstacles to speech.

After exploring another eight Broca patients, the defect confirmed: lesions in the lower left area of ​​the frontal lobe. This symbolized for the first time in history that the brain area was associated with a tongue. Ten years later, in 1871, German neurologist Carl Wernicke discovered another area of ​​the brain related to the tongue, located in the back of the left side of the temporary lobe. He noted that people with lesions in this area could present speech, but their speech was difficult to understand.

Thus,

neurologists have theorized time that there must be a nerve pathway connects the Wernicke region with Brod. It was believed that such a connection allowed people not only to speak, but also to do it coherent. This nerve path that consists of whiteSummer for connecting areas of the nervous system relatively distant apart is called arc fascicles.

, however, other neurologists question the theory of the arc of the fasculus regarding language processing. As a result of recent neuroradiological studies, some scientists argue that the bundle connects the receptive areas at the back with premotor/motor areas instead of the Broca region. In general, however, arched fasculus provides a connection between time, parietal and frontal lobes of the brain.
