Abstract

The article discusses the pathogenetic and clinical aspects of vestibular and cochlear disorders such as dizziness, tympanophony, and vestibular ataxia. It is emphasized that the vestibular system provides not only the relationship between motor and sensory processes but its functions are also much more significant. The uniqueness of the vestibular system consists of its multisensory cortical projections. The analysis of vestibular information is provided by a network of connections, which its epicenter is located in the depths of the Sylvian fissure and the surrounding parietal-temporal regions, and the retroinsular region. It has been suggested that the vestibular cortex can be considered a network of connections between all cortical areas receiving impulses from the vestibular system, including regions where vestibular information affects the analysis of other sensory (i.e., somatosensory and visual) and motor activity. The pathogenetic mechanisms of dizziness, tympanophony, and ataxia are discussed. The conclusion is made about the significance of connectome disorders in this patient category.
