various dimensions of the human vestibular aqueduct were evaluated in two groups, patient and control, and these measurements were compared. both groups were examined clinically, followed by audiometric evaluation and temporal bone high resolution ct scan. it was found that in approximately one third of the patient group (with idiopathic snhl), the vestibular aqueduct was 1.5 mm or larger. also...

Although considerable evidence suggests that the vestibular system regulates sympathetic outflow during movement and changes in posture, little is known about relative vestibular influences on activity of different sympathetic nerves and sympathetic efferents with different functions. In the present study, we demonstrated that electrical stimulation of the vestibular nerve in the cat elicited r...

Following you will find a brief description of the book done, as accorded with Alessandro De Stefano, to publish in Int Tinnitus J Vertigo: Diagnosis and Management of Jaypee Brother Publisher, is a new book in the field of vestibular disorders. This publication includes several topics ranging from anatomy of vestibular system to the rehabilitation after a vestibular disease. The book, edited b...

Vestibular compensation, which is the behavioral recovery from vestibular dysfunction produced by unilateral labyrinthectomy (UL), is attributed to functional and structural reorganization of neural networks in the central vestibular system. To assess the possible contribution of brain-derived neurotrophic factor (BDNF) to this recovery process, we investigated changes in mRNA expression levels...

BACKGROUND The concept of the vestibular implant is primarily to artificially restore the vestibular function in patients with a bilateral vestibular loss (BVL) by providing the central nervous system with motion information using electrical stimulation of the vestibular nerve. Our group initiated human trials about 10 years ago. METHODS Between 2007 and 2013, 11 patients with a BVL received ...

background and aim: caffeine at low doses blocks adenosine receptors. these receptors are present in all parts of the body including auditory and vestibular system. this study aimed to evaluate the effects of caffeine on cervical vestibular evoked myogenic potential (cvemp). methods: in this interventional double-blind study, 40 cases (20 females and 20 males) aged 18-25 years were randomly ass...

For decades it has been speculated that there is a close association between the vestibular system and spatial memories constructed by areas of the brain such as the hippocampus. While many animal studies have been conducted which support this relationship, only in the last 10 years have detailed quantitative studies been carried out in patients with vestibular disorders. The majority of these ...

The last decade has witnessed advances in understanding the roles of receptors of neurotrophin and glutamate in the vestibular system. In the first section of this review, the biological actions of neurotrophins and their receptors in the peripheral and central vestibular systems are summarized. Emphasis will be placed on the roles of neurotrophins in developmental plasticity and in the mainten...

Recent studies have shown that vestibular stimulation can influence affective processes. In the present study, we examined whether emotional information can also modulate vestibular perception. Participants performed a vestibular discrimination task on a motion platform while viewing emotional pictures. Six different picture categories were taken from the International Affective Picture System:...

Vestibular damage can induce locomotor abnormalities in both animals and humans. Rodents with bilateral vestibular loss showed vestibular deficits syndrome such as circling, opisthotonus as well as locomotor and exploratory hyperactivity. Previous studies have investigated the changes in the dopamine system after vestibular loss, but the results are inconsistent and inconclusive. Numerous evide...
