Activation of vestibular cortex areas, visual motion‐sensitive areas, and ocular motor areas exhibited a significant right‐hemispheric dominance.

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 . Most remarkably, vestibular heading signals in the ventral intraparietal (VIP 2020-01-29 · Attention Networks in the Parietooccipital Cortex Modulate Activity of the Human Vestibular Cortex during Attentive Visual Processing.

A cortical representation has been postulated with the argument that there is a true vestibular sensation and that vestibular signals might also be useful for higher motor mechanisms (Spitzer, 1924). Foerster (1936) showed that auras that accompany seizures originating from foci within the intraparietal sulcus may include vestibular sensations.

There are four 2nd order vestibular nuclei: the inferior, medial, lateral (Deiter’s) and superior vestibular nuclei. The core of the vestibular cortex (shown in red) is located in the midposterior Sylvian fissure and consists of the parieto-insular vestibular cortex area (PIVC) and the posterior insular cortex area [PIC; visual posterior Sylvian area (VPS) in nonhuman primates]. vestibular area of the cerebral cortex after relaying in the ventral posterior nuclei of thalamus; Functions of the Vestibular System.

Little is known about the structural connectivity pattern of these areas. Se hela listan på physio-pedia.com The vestibular cortex intimately interacts with the visual cortex to match the two 3‐D orientation maps (perception of verticality, room‐tilt illusion) and mediates self‐motion perception by means of a reciprocal inhibitory visual‐vestibular interaction. Via the subnuclei of this relay station, vestibular information in animals reaches several separate and distinct cortex areas such as the parieto-insular vestibular cortex (PIVC) in the posterior insula, adjacent retroinsular areas and the granular insular region (Grüsser et al., 1982, 1990a, b; Guldin and Grüsser, 1996), the visual temporal sylvian area VTS posterior to PIVC (Guldin and The vestibular cortical system presented here includes such different cortical regions as the premotor regions of the frontal cortex (area 6v, area VC) as well as parietal areas (area 2v, area 7), temporal areas (VPS and MST) and a central core region called PIVC, consisting of parts of the granular insula and the retroinsular region close to the acoustic cortex.
