An Implanted Vestibular Prosthesis Improves Spatial Orientation in Animals with Severe Vestibular Damage [PDF]

The Journal of Neuroscience, 2021
Gravity is a pervasive environmental stimulus, and accurate graviception is required for optimal spatial orientation and postural stability. The primary graviceptors are the vestibular organs, which include angular velocity (semicircular canals) and linear acceleration (otolith organs) sensors.

A CMOS Neural Interface for a Multichannel Vestibular Prosthesis [PDF]

IEEE Transactions on Biomedical Circuits and Systems, 2016
We present a high-voltage CMOS neural-interface chip for a multichannel vestibular prosthesis (MVP) that measures head motion and modulates vestibular nerve activity to restore vision- and posture-stabilizing reflexes. This application specific integrated circuit neural interface (ASIC-NI) chip was designed to work with a commercially available ...

Vestibular Perception following Acute Unilateral Vestibular Lesions. [PDF]

, 2013
Little is known about the vestibulo-perceptual (VP) system, particularly after a unilateral vestibular lesion. We investigated vestibulo-ocular (VO) and VP function in 25 patients with vestibular neuritis (VN) acutely (2 days after onset) and after ...

One Step Closer to a Functional Vestibular Prosthesis [PDF]

The Journal of Neuroscience, 2013
To create a stable representation of the visual scene, the brain relies on information provided by the vestibular and proprioceptive systems. Two well studied examples of this are the vestibular-ocular reflex, which counter-rotates the eyes during head rotation to reduce retinal image motion ...

Vestibular modulation of spatial perception [PDF]

, 2013
Vestibular inputs make a key contribution to the own sense of spatial location. While the effects of vestibular stimulation on visuo-spatial processing in neurological patients have been extensively described, the normal contribution of vestibular ...

Multisensory Interactions between Vestibular, Visual and Somatosensory Signals. [PDF]

, 2015
Vestibular inputs are constantly processed and integrated with signals from other sensory modalities, such as vision and touch. The multiply-connected nature of vestibular cortical anatomy led us to investigate whether vestibular signals could ...

HSV-1 not only in human vestibular ganglia but also in the vestibular labyrinth [PDF]

, 2001
Reactivation of herpes simplex virus type 1 (HSV-1) in the vestibular ganglion (VG) is the suspected cause of vestibular neuritis (VN). Recent studies reported the presence of HSV-1 DNA not only in human VGs but also in vestibular nuclei, a finding that ...

Interproximal papilla volumization using vestibular incision subperiosteal tunneling access technique in esthetic rehabilitation

Contemporary Clinical Dentistry, 2020
An accurate diagnostic and interdisciplinary approach is essential for obtaining suitable, conservative, and predictable results in areas with high esthetic demand. Patients reporting with an improper prosthesis that has a black triangle pose a challenge

Perilymphatic gusher in osteogenesis imperfecta

Otolaryngology Case Reports, 2021
Perilymphatic gusher is a rare event during stapes surgery that can have dramatic consequences on hearing outcomes. While gusher has been reported in X-linked deafness and otosclerosis, this is the first report of perilymphatic gusher during stapedotomy ...

The modified ampullar approach for vestibular implant surgery: Feasibility and its first application in a human with a long-term vestibular loss

Frontiers in Neurology, 2012
Objective: To assess, for the first time in a human with a long-term vestibular loss, a modified approach to the ampullae and the feasibility of evoking a VOR by ampullar stimulation.Material and methods: Peroperative stimulation of the ampullae, using ...
