The vestibulo-ocular reflex (VOR) is essential in our daily life to stabilize retinal images during head movements. Balanced vestibular functionality secures optimal reflex performance which otherwise can be distorted by peripheral vestibular lesions. Luckily, vestibular compensation in different neuronal sites restores VOR function to some extent over time. Studying vestibular compensation giv...

Concern that vestibular stimulation may induce seizures in seizure-prone children has been based on hearsay and unconfirmed clinical impressions of practicing therapists. To clarify this issue, we took electroencephalographic recordings of seizure-prone children before, during, and after specific vestibular stimulation. Ten children with seizure histories, 5, to 15 years of age, were exposed to...

Objective: The main goal of this study is to clarify the electroencephalogram (EEG) characteristics stress response caused by vestibular endurance training under real conditions. Methods: Ten pilot trainees received a series acute anti-vertigo stimulations on rotary ladder while recording electroencephalographic data (64 electrodes). Afterward, ability subject was tested for best performance af...

Reports of vestibular deficits and related impairments in children are increasing in number. However, vestibular dysfunction in childhood appears to be an under-reported and overlooked entity. This report provides an overview of current literature regarding the incidence of vestibular deficits in children, the related impairments of gaze stability and balance and intervention for vestibular rel...

In addition to the deficits in the vestibulo-ocular and vestibulo-spinal reflexes that occur following vestibular dysfunction, there is substantial evidence that vestibular loss also causes cognitive disorders, some of which may be due to the reflexive deficits and some of which are related to the role that ascending vestibular pathways to the limbic system and neocortex play in spatial orienta...

Modern diagnostic methods such as video head impulse test and cervical and ocular vestibular evoked myogenic potentials allow to measure canal and otolith function quantitatively and objectively. These methods contribute to a complex assessment of the functional integrity of all 5 sensory elements of the vestibular organ for the first time. Moreover, in combination with additional vestibular te...

Efferent circuits within the nervous system carry nerve impulses from the central nervous system to sensory end organs. Vestibular efferents originate in the brainstem and terminate on hair cells and primary afferent fibers in the semicircular canals and otolith organs within the inner ear. The function of this efferent vestibular system (EVS) in vestibular and motor coordination though, has pr...

Eye movements were recorded in the pigmented rat during vestibular, optokinetic and combined visual-vestibular stimulation. The dominant time constant in pigmented rats, tested during angular vestibular stimulation in darkness, is about two times longer than the cupular time constant. The gain and the duration of nystagmus, achieved by angular vestibular stimulation, can be enhanced by visual i...

Nasal vestibular stenosis is not only an esthetic, but also a functional problem for the patient. It is caused by disruption of the nasal vestibular lining with secondary proliferation of granulation and fibrous tissue. Various causes account for the development of nasal vestibular stenosis, including trauma, infection, and iatrogenic injury to the vestibular skin. Although a number of techniqu...
