The thalamocortical vestibular system in animals and humans [PDF]
The vestibular system provides the brain with sensory signals about three-dimensional head rotations and translations. These signals are important for postural and oculomotor control, as well as for spatial and bodily perception and cognition, and they are subtended by pathways running from the vestibular nuclei to the thalamus, cerebellum and the ...

Aging of the Human Vestibular System
Aging affects every sensory system in the body, including the vestibular system. Although its impact is often difficult to quantify, the deleterious impact of aging on the vestibular system is serious both medically and economically. The deterioration of the vestibular sensory end organs has been known since the 1970s; however, the measurable impact ...

Ultrastructural Aspects of the Human Peripheral Vestibular System
Acta Oto-Laryngologica, 1990The sensory epithelia from the membranous labyrinths of 4 patients were examined by transmission electron microscopy. The distribution ratio of type 1 to type 2 cells was recorded, compared for each sensory area and correlated with age. An ultrastructural assessment confirmed generalized patterns consistent with autolytic and preparation artefact, viz.

Adaptation to Steady-State Electrical Stimulation of the Vestibular System in Humans
Objectives: Efforts are being made toward the development of a vestibular implant. If such a device is to mimic the physiology of the vestibular system, it must first be capable of restoring a baseline or “rest” activity in the vestibular pathways and then modulating it according to the direction and velocity of

The saccule is one of the vestibular sensory organs of the inner ear. It detects head movements and provides information to maintain balance and orient in space. Despite its critical role, very little is known about its neurotransmission and regulation.

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.

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.
