The Vestibular is a competitive examination and is the primary and widespread entrance system used by Brazilian universities to select the students admitted. The Vestibular usually takes place from November to January, right before the start of school year in February or March, although certain universities hold it every semester. The exams often span several days, usually two, with different disciplines being tested each day.

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 Anatomy and Physiology, Systems. As compared to the wealth of knowledge ascertained about the primary sensory cortices, The Parietal Lobe. The vestibular cortex differs in various ways from other sensory cortices. It consists of a network Neuro-ophthalmology.

In monkeys, the parietoinsular vestibular cortex (PIVC) at the posterior 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 somatosensory stimuli. The parieto-insular vestibular cortex (PIVC) and the posterior insular cortex (PIC) are key regions of the cortical vestibular network, both located in the midposterior section of the lateral sulcus.

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'. However, no clear concept has emerged as to where and how the vestibular information is processed in the cerebral cortex.

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. The vestibular sensory organs are located in the petrous part of the temporal bone in close proximity to the cochlea, the auditory sensory organ. 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]. vestibular area of the cerebral cortex after relaying in the ventral posterior nuclei of thalamus; Functions of the Vestibular System.
