The hair cells in the Balance information provided by the peripheral sensory organs—eyes, muscles and joints, and the two sides of the vestibular system—is sent to the brain stem. function of a core region in the vestibular cortex of humans that is located in the midposterior Sylvian ﬁssure and referred to as the parieto-insular vestibular cortex (PIVC). Previous studies have investigated PIVC by using vestibular or visual motion stimuli and have observed activations that were distributed across multiple The vestibular cortex differs in various ways from other sensory cortices. It consists of a network of several distinct and separate temporoparietal areas. Its core region, the parietoinsular vestibular cortex (PIVC), is located in the posterior insula and retroinsular region and includes the parietal operculum. Although electrophysiological and cytoarchitectonic data in animals demonstrate several multisensory areas rather than a single primary vestibular cortex, the parieto‐insular vestibular cortex seems to represent the integration center of the multisensory vestibular cortex areas within the parietal lobe. Vestibular dysfunction is most commonly caused by head injury, aging, and viral infection.

Parieto-Insular Vestibular Cortex listed as PIVC. Parieto-Insular Vestibular Cortex - How is Parieto-Insular Vestibular Cortex abbreviated? https: Download Citation | The Vestibular Cortex. | Over the past few decades, various cortical regions in primates have been labeled as vestibular: area 2v, area 3, area 7, superior temporal gyrus vestibular sensors. In monkeys, the parieto-insular vestibular cortex (PIVC) at the poste-rior end of the insula is the core region of the vestibular cortex, as it contains the greatest number of vestibular-driven neurons (17, 31). Most PIVC neurons respond jointly to head accelerations and to optokinetic and neck so-matosensory stimuli. Se hela listan på scholarpedia.org For example, vestibular heading signals follow a representation that is intermediate between head- and eye-centered in the dorsal medial superior temporal area (MSTd) (15, 19), but intermediate between head- and body-centered in the parietoinsular vestibular cortex .

The location is not well defined, but some research indicates a right hemisphere dominance.

Although electrophysiological and cytoarchitectonic data in animals demonstrate several multisensory areas rather than a single primary vestibular cortex, the parieto‐insular vestibular cortex seems to represent the integration center of the multisensory vestibular cortex areas within the parietal lobe. Vestibular dysfunction is most commonly caused by head injury, aging, and viral infection. Other illnesses, as well as genetic and environmental factors, may also cause or contribute to vestibular disorders. Disequilibrium: Unsteadiness, imbalance, or loss of equilibrium; often accompanied by spatial disorientation.

The vestibular system is a sensory system that is responsible for providing our brain with information about motion, head position, and spatial orientation; it also is involved with motor functions that allow us to keep our balance, stabilize our head and body during movement, and maintain posture. there is debate over exactly where the vestibular cortex is: some people put it close to auditory cortex in the superior temporal gyrus, others at the end of somatosensory cortex where it joins with motor cortex The axons travel in the vestibular portion of the VIIIth cranial nerve and enter the brain stem at the pontomedullary junction. There are four 2nd order vestibular nuclei: the inferior, medial, lateral (Deiter’s) and superior vestibular nuclei.
