Diagnostic criteria for persistent postural-perceptual dizziness (PPPD) are presented and it is classified as a chronic functional vestibular disorder, which is not a structural or psychiatric condition.
Differential effects of central versus peripheral vision on egocentric and exocentric motion perception
Simultaneous presentation of conflicting central and peripheral optokinetics stimuli has shown that exocentric orientation depends on the peripheral stimulus whereas optokinetic nystagmus and egocentric motion perception rely on the center of the visual field.
Visual-Vestibular Interaction: Effects on Self-Motion Perception and Postural Control
The sensation of self-motion is a common visual illusion which allows inferences concerning visual-vestibular interaction. It may be perceived while gazing at moving clouds, streaming water, or when…

A PET activation study on CV was conducted and it was shown for the first time that visual motion stimulation with CV not only activates a medial parieto-occipital visual area bilaterally, separate from middle temporal/medial superior temporal areas, it also simultaneously deactivates the pariete-insular vestibular cortex.

Stimulus-dependent, inhibitory vestibular-visual, and nociceptive-somatosensory interactions may be functionally significant for processing perception and sensorimotor control.
Dominance for vestibular cortical function in the non-dominant hemisphere.
This PET study showed for the first time that cortical and subcortical activation by vestibular caloric stimulation depends on the handedness of the subjects and on the side of the stimulated ear.
Vestibular cortex lesions affect the perception of verticality
Although electrophysiological and cytoarchitectonic data in animals demonstrate several multisensory areas rather than a single primary vestibular cortex, the parieto‐insular vestibul cortex seems to represent the integration center of the multisENSory vestIBular cortex areas within the parietal lobe.
Visual stabilization of posture. Physiological stimulus characteristics and clinical aspects.
The purpose of the present investigation was to obtain quantitative data in man by means of posturography of fore-aft and lateral body sway in relation to different visual stimulus characteristics, which demonstrates clinical relevance in patients with oculomotor disturbances.
Vestibular loss causes hippocampal atrophy and impaired spatial memory in humans.
The current data on BVL patients and bilateral hippocampal atrophy revive the idea that a major--and probably phylogenetically ancient--function of the archicortical hippocampal tissue is still evident in spatial aspects of memory processing for navigation, and demonstrate for the first time in humans that spatial navigation critically depends on preserved vestibular function.
