Die menschliche Gleichgewichtsfunktion wird durch ein sogenanntes Raumkonzept mit Einspeisung von Informationen aus der Gleichgewichtstetrade, nämlich Auge, Vestibularis, Cochlea und Propriozept im menschlichen Hirnstamm gebildet. Ergänzt wird die Gleichgewichtsregulation durch cerebelläre und kortikale Musterverarbeitungsprozesse und Speicherinhalte. Gleichgewichtsfunktionsstörungen können an den verschiedensten Orten der genannten Rezeptoren, wie auch innerhalb des Zentralnervensystemes entstehen. Für die diagnostische Suche […]

A study of cerebral cortical projections in Ménière Syndrome has been carried out. The analysis was made by Brain Electric Tomography – Loreta and the most significant areas have been evaluated by means of Statistical non Parametric Mapping – SnPM. The regular Ménière Syndrome (vertigo-hypoacusis-tinnitus) has a very important cortical representation in frontal areas Brodmann […]

Many authors have reported different useful studies on the evaluation of the nystagmus which may be spontaneous and induced, any of these authors have been devoted to the study of vestibulo-spinal reflexes.1,2 The diagnosis of patients in modern neuro-otological centres has to include not only the history and examination, but also objective and quantitative tests. […]

The goal of this work is to study the vestibular system of whiplash people using a 3D dCCG system. A new experimental set-up, based on optoelettronic technique, was developed to evaluate the 3D pattern of movement of head and trunk in different experimental set-ups. The exam protocol is very close to the classical one with […]

Introduction: The goal of this study is to evaluate the role of vestibular rehabilitation (VR) with feed-back techniques such us dynamic posturography compared with conventional postural and oculocephalic maneuvers, after vestibular neurectomies (VN), in patients with unilateral Ménière disease, and to demonstrated if instrumental (VR) improves recovery of balance. Material and Methods: Sixty three patients […]

Vestibular nuclei receive signals from the skin, muscle, and viscera, although the pathways conveying these nonlabyrinthine inputs to the vestibular nucleus neurons are unknown. Experimental data show that an anatomical substrate is present for somatosensory and visceral inputs to influence the activity of cells in the autonomic region of the vestibular nuclei and suggest that […]

Ketamine, or ketamine hydrochloride, is a non-barbiturate, rapid-acting disassociative anesthetic: the primary central nervous system action of ketamine appears to be a non-competitive block of NMDA (named after the selective agonist N-methyl-D-aspartate). In the current study, we examined the effect of ketamine on cortical and subcortical function by exploiting evoked eye movements: we analyzed the […]
