Where is the intraparietal sulcus located?
parietal lobe
Intraparietal sulcus runs horizontally at the middle of the parietal lobe. The intraparietal sulcus (IPS) is located on the lateral surface of the parietal lobe, and consists of an oblique and a horizontal portion.
What does intraparietal sulcus mean?
[ ĭn′trə-pə-rī′ĭ-təl ] n. A horizontal sulcus extending from the postcentral sulcus and dividing into two branches to form with the postcentral sulcus a figure H that divides the parietal lobe into a superior and an inferior lobule.
Where is the gyrus located?
A gyrus (plural: gyri) is the name given to the bumps ridges on the cerebral cortex (the outermost layer of the brain). Gyri are found on the surface of the cerebral cortex and are made up of grey matter, consisting of nerve cell bodies and dendrites.
Where is the temporal sulcus located?
temporal lobe
The superior temporal sulcus (STS) is the sulcus separating the superior temporal gyrus from the middle temporal gyrus in the temporal lobe of the brain.
Where is the superior temporal line?
The superior temporal line is an arching ridge along the lateral surface of the skull; it begins as a continuation of the upper posterior border of the zygomatic bone and continues as a broad arch along the frontal and parietal bones, above and roughly parallel to the upper edge of the temporal bone.
What is the intraparietal sulcus?
[edit on Wikidata] The intraparietal sulcus (IPS) is located on the lateral surface of the parietal lobe, and consists of an oblique and a horizontal portion. The IPS contains a series of functionally distinct subregions that have been intensively investigated using both single cell neurophysiology in primates and human functional neuroimaging.
Is the parietal lobe involved in reflex saccades?
The parietal lobe contains the intraparietal sulcus, an area involved in saccade generation, and a lesion in this region results in increased saccadic latencies and a reduced amplitude of contralaterally directed reflexive saccades (Pierrot-Deseilligny et al., 1987) and memory-guided saccades ( Muri et al., 2000 ).
What is the function of the caudal sulcus?
Monkey caudal intraparietal sulcus (cIPS) contains neurons selective for binocular disparity and 3D surface orientation and may provide information for the visual guidance of hand action (Sakata, H. et al., 1997; 1998; 1999 ).
What is the posterior parietal cortex in monkeys?
The cortical areas surrounding the IPS in monkeys are referred to collectively as the posterior parietal cortex. PPC is normally subdivided anatomically into a rostral division – the superior parietal lobule (SPL) – and a caudal zone – the inferior parietal lobule (IPL). The SPL and IPL in monkeys were named areas 5 and 7 by Brodmann (1909).
