Neurootology

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 […]

Head stabilization is necessary during human locomotion in order to contrubute to perception of a stable visual field. Head stabilization is du to the cooperation between vestibular system and proprioception. According to cranio-corpographic experience Authors used a device based on two accelormeters place, respectevely, on th head and the trunk of the subject. Head stabilization […]

Objectives: An isolated directional preponderance (PD) on bithermal caloric testing leaves many doubts to neurootology. It is considered by some to be as a transient, benign disorder (Halmagy, GM et al). We tried to elucidate if the PD can be considered important for the clinical diagnosis, without anamnesis. Methods: A retrospective study of 136 electronystagmographies, […]
