Its core region, the parietoinsular vestibular cortex (PIVC), is located in the posterior insula and retroinsular region and includes the parietal operculum. 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. 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]. 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).

2002) that several cortical regions including the parieto-insular vestibular cortex (PIVC) are consistently active during the resulting sensations of movement or tilt. Activation of vestibular cortex areas, visual motion‐sensitive areas, and ocular motor areas exhibited a significant right‐hemispheric dominance. 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.

It consists of a network Neuro-ophthalmology. Christopher The vestibular cortex. Its locations, functions, and disorders Evidence is presented that the multisensory parieto-insular cortex is the human homologue of the parieto-insular vestibular cortex (PIVC) in the monkey and is involved in the perception of verticality and self-motion. Vestibular cortex. The vestibular nuclei and vestibular cerebellum send projections to the regions of the thalamus that are sensitive to vestibular stimulation (reviewed in Lopez and Blanke, 2011). In turn, these regions of the thalamus send ascending projections to areas of cortex. Very different areas of the primate cortex have been labelled as 'vestibular'.
