What is an intralarietal sulcus?

Intrarietal sulcus (IPS), which is also known as an interparietal crack, is a long slot located in a parietal lobe of the human brain. The primary function of the intararietal sulcus is related to the direction of eye movements, by precise attainment or prolongation of the arms and visual attention, although it is also assumed that it plays a role in understanding numerical symbolism and recognizing the intention of others through visual stimuli. IPS does not run in a straight line from its starting point to the end point, instead of the meanders from the lateral or side, part of the parietal lobe to its end in the occipital lobe.

The external coverage of the human brain is the brain, and it is affected by gyri and fris. The cerebrum is divided into the right and left hemispheres of a large longitudinal crack, which is also known as a medium longitudinal crack, longitudinal brain crack, longitudinal crack and internaliispheric crack. Both brain hemispheres are divided into four lobes: front lobes located in the forehead area, parietal lobes at the top andOn the sides of the head, temporary lobes on the sides of the head under the parietal lobes and ocre lobes in the back of the head.

.

both left and right parietal lobes contain intraphone sulcus. The interparietal crack is divided into two perpendicular lines at its lower end and when it is attached to the postcentral sulk at its upper end, it forms the shape of "H", which divides the parietal lobe into the superior and lower lobul. In some brains, it is an intralarietal sulcus a continuous line, in others it is divided into two lines. In approximately two -thirds of the brain begins with intra -paralytal sulcus at the center of the postcentral sulcus or in its vicinity, which is also located in a parietal lobe. IPS travels down to the top of the occipital lobe, where it ends in the transverse occipital sulcus.

Interparietal crack has sections that spread horizontally and parts that spread obliquely. Intararietal sulcus can have different Czechst branches that may point up or down. The highest point branch of down that can reach either from the intraphone sulk or postcentral sulk is called the primary inter -production sulcus. The branch pointing the routing substances immediately below the primary medium sulcus, which ranges from the intraparpiteal sulk, is called the secondary intermediate sulcus intermediate.
