A growing number of studies indicate that cognitive complaints are common in patients with peripheral vestibular disorders. A better understanding of how vestibular disorders influence cognition in these patients requires a clear delineation of the cognitive domains affected by vestibular disorders. Here, we compared the consequences of left and right vestibular neurectomy on third-person perspective taking-a visuo-spatial task requiring mainly own-body mental imagery, and on 3D objects mental rotation imagery-requiring object-based mental imagery, but no perspective taking. Patients tested 1 week after a unilateral vestibular neurectomy and a group of age- and gender-matched healthy participants played a virtual ball-tossing game from their own first-person perspective (1PP) and from the perspective of a distant avatar (third-person perspective, 3PP). Results showed larger response times in the patients with respect to their controls for the 3PP taking task, but not for the 1PP task and the 3D objects mental imagery. In addition, we found that only patients with left vestibular neurectomy presented altered 3PP taking abilities when compared to their controls. This study suggests that unilateral vestibular loss affects mainly own-body mental transformation and that only left vestibular loss seems to impair this cognitive process. Our study also brings further evidence that vestibular signals contribute to the sensorimotor bases of social cognition and strengthens the connections between the so far distinct fields of social neuroscience and human vestibular physiology.

This pilot study aimed to investigate the effects of incorporating vibrotactile sensory augmentation (SA) on balance performance among people with unilateral vestibular disorders (UVD).
People with vestibular loss present a deficit in the vestibular system, which is primarily responsible for promoting postural control, gaze stabilization, and spatial orientation while the head moves....
Level-2 visuo-spatial perspective-taking is an embodied process during which the perspective-taker mentally simulates a movement of his or her body into the location of the target. Evidence for the em...
Vestibular rehabilitation is an exercise-based program that has been in existence for over 70 years. A growing body of evidence supports the use of vestibular rehabilitation in patients with vestibula...
Earth's gravity acts both as a mechanical stimulus on the body and as a sensory stimulus to the vestibular organ, which is transmitted into the brain. The vestibular system has been recently highlight...
The purpose of this study is to determine whether vestibular disorders could affect visuo-spatial cognition. Visuo-spatial cognition will be evaluated using a new computerized test using a...
In this study the investigators propose to apply cognitive training, which has been largely used in the realm of age-related cognitive decline, dementia, and Alzheimer's disease, in a nove...
Unilateral vestibular lesions are frequent and disabling pathologies causing a set of oculomotor, postural and perceptual symptoms. These symptoms reduce over time according to a vestibula...
The investigators objective is twofold. Investigators propose to study how the vestibular and auditory information interact in the construction of coherence between the staff and extrapers...
Spanish population with unilateral peripheral vestibular disorders.
Measures of spatial cognition and memory.
Methods used to take into account and incorporate spatial autocorrelation and regional variation into regression analysis models of data that has spatial dependency, and also to provide information on the spatial relationships among the variables.
The vestibular part of the 8th cranial nerve (VESTIBULOCOCHLEAR NERVE). The vestibular nerve fibers arise from neurons of Scarpa's ganglion and project peripherally to vestibular hair cells and centrally to the VESTIBULAR NUCLEI of the BRAIN STEM. These fibers mediate the sense of balance and head position.
Vestibular nucleus lying immediately superior to the inferior vestibular nucleus and composed of large multipolar nerve cells. Its upper end becomes continuous with the superior vestibular nucleus. (From Dorland, 28th ed)
Pathological processes of the VESTIBULAR LABYRINTH which contains part of the balancing apparatus. Patients with vestibular diseases show instability and are at risk of frequent falls.
