Probing the human vestibular system with galvanic stimulation
Journal of Applied Physiology, 2004Galvanic vestibular stimulation (GVS) is a simple, safe, and specific way to elicit vestibular reflexes. Yet, despite a long history, it has only recently found popularity as a research tool and is rarely used clinically. The obstacle to advancing and exploiting GVS is that we cannot interpret the evoked responses with certainty because we do not ...

Temporal Bone Studies of the Human Peripheral Vestibular System
Annals of Otology, Rhinology & Laryngology, 2000Quantitative assessments of vestibular hair cells and Scarpa's ganglion cells were performed on temporal bones from 24 patients with well-documented Meniere's disease. Of these, 18 had unilateral disease and 6 had bilateral disease.

Brain Stimulation, 2018 There is strong evidence that the presence of noise can enhance information processing in sensory systems via stochastic resonance (SR).To examine the presence of SR in human vestibulospinal reflex function.Healthy subjects were stimulated with 1 Hz sinusoidal GVS of varying amplitudes (0-1.9 mA).

The possible effect of human menopausal gonadotropin on the audio-vestibular system
Auris Nasus Larynx, 2018Human menopausal gonadotropin (HMG) is one of the commonest drugs used for ovarian stimulation with no reports on the audio-vestibular system. This study aims to examine HMG on the hearing profile of patients planning intracytoplasmic sperm injection (ICSI).This prospective study was conducted from June 2016 to June 2017 in a tertiary referral hospital.

Peripheral Vestibular System Disease in Vestibular Schwannomas
Otology & Neurotology, 2015Dizziness is a common symptom in patients with vestibulo-cochlear schwannoma (VS), and several recent studies have identified this symptom as the single most important concerning the quality of life. Clinical and histological observations regarding hearing loss have suggested that this may be caused by both cochlear and retrocochlear mechanisms ...

Effect of Transdermally Administered Scopolamine on the Vestibular System in Humans
Acta Oto-Laryngologica, 1993In order to elucidate the effect of scopolamine on the vestibular system in humans, various experimentally-induced forms of nystagmus, i.e. caloric nystagmus, rotational nystagmus, optokinetic nystagmus, visual-vestibular interaction and optokinetic after nystagmus, were evaluated before and after the administration of two pieces of Scopoderm-TTS or ...

Visualization of Human Vestibular Aqueduct with Computeraided Serial Section Reconstruction System
Acta Oto-Laryngologica, 1988 The computer-aided serial section reconstruction system (SERSERS) was employed to elucidate the entire configuration of the vestibular aqueduct in the human temporal bone. The advantages and the disadvantages of this system are discussed in comparison with several conventional methods such as X-ray visualization, plastic casting and graphic ...

Tuning and sensitivity of the human vestibular system to low-frequency vibration
Neuroscience Letters, 2008Mechanoreceptive hair-cells of the vertebrate inner ear have a remarkable sensitivity to displacement, whether excited by sound, whole-body acceleration or substrate-borne vibration. In response to seismic or substrate-borne vibration, thresholds for vestibular afferent fibre activation have been reported in anamniotes (fish and frogs) in the range ...

Histopathology of the Peripheral Vestibular System after Cochlear Implantation in the Human
Otology & Neurotology, 2006The objective of this study was to describe the histology of the peripheral vestibular system in temporal bones from patients who in life had undergone cochlear implantation and to correlate the findings with previous reports of vestibular dysfunction after cochlear implantation.

Sliding Mode Control of the Human Vestibular System
Volume 1: Development and Characterization of Multifunctional Materials; Modeling, Simulation and Control of Adaptive Systems; Structural Health Monitoring, 2012An original sliding mode controller is designed, based on an existing mathematical model for response control of the human vestibular system. The human vestibular system is located in the inner ear and significantly contributes to the functions of detecting head motion, maintaining balance and posture, and realizing gaze stabilization.
