Motor signs such as head tilt and body lateropulsion, components of ocular tilt reaction, are typical for vestibular lesions of the peripheral vestibular organ and the pontomedullary brainstem (vestibular nucleus). They are less frequent in midbrain lesions (interstitial nucleus of Cajal) and rare in cortical lesions.

Vestibular cortex is the portion of the cerebrum which responds to input from the vestibular system. The location is not well defined, but some research indicates a right hemisphere dominance. Lesions of the vestibular nucleus impair function.

Vestibular cortex

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. Other illnesses, as well as genetic and environmental factors, may also cause or contribute to vestibular disorders.

Se hela listan på 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.
