Sustained and Transient Vestibular Systems: A Physiological Basis for Interpreting Vestibular Function.

Frontiers in neurology

Curthoys IS, MacDougall HG, Vidal PP, de Waele C.
PMID: 28424655
Front Neurol. 2017 Mar 30;8:117. doi: 10.3389/fneur.2017.00117. eCollection 2017.

Otolithic afferents with regular resting discharge respond to gravity or low-frequency linear accelerations, and we term these the static or sustained otolithic system. However, in the otolithic sense organs, there is anatomical differentiation across the maculae and corresponding physiological...

A Novel Saccadic Strategy Revealed by Suppression Head Impulse Testing of Patients with Bilateral Vestibular Loss.

Frontiers in neurology

de Waele C, Shen Q, Magnani C, Curthoys IS.
PMID: 28868046
Front Neurol. 2017 Aug 18;8:419. doi: 10.3389/fneur.2017.00419. eCollection 2017.

OBJECTIVE: We examined the eye movement response patterns of a group of patients with bilateral vestibular loss (BVL) during suppression head impulse testing. Some showed a new saccadic strategy that may have potential for explaining how patients use saccades...

Electrophysiological Measurements of Peripheral Vestibular Function-A Review of Electrovestibulography.

Frontiers in systems neuroscience

Brown DJ, Pastras CJ, Curthoys IS.
PMID: 28620284
Front Syst Neurosci. 2017 May 31;11:34. doi: 10.3389/fnsys.2017.00034. eCollection 2017.

Electrocochleography (EcochG), incorporating the Cochlear Microphonic (CM), the Summating Potential (SP), and the cochlear Compound Action Potential (CAP), has been used to study cochlear function in humans and experimental animals since the 1930s, providing a simple objective tool to...

The Video Head Impulse Test.

Frontiers in neurology

Halmagyi GM, Chen L, MacDougall HG, Weber KP, McGarvie LA, Curthoys IS.
PMID: 28649224
Front Neurol. 2017 Jun 09;8:258. doi: 10.3389/fneur.2017.00258. eCollection 2017.

In 1988, we introduced impulsive testing of semicircular canal (SCC) function measured with scleral search coils and showed that it could accurately and reliably detect impaired function even of a single lateral canal. Later we showed that it was...

Otolithic Receptor Mechanisms for Vestibular-Evoked Myogenic Potentials: A Review.

Frontiers in neurology

Curthoys IS, Grant JW, Burgess AM, Pastras CJ, Brown DJ, Manzari L.
PMID: 29887827
Front Neurol. 2018 May 25;9:366. doi: 10.3389/fneur.2018.00366. eCollection 2018.

Air-conducted sound and bone-conduced vibration activate otolithic receptors and afferent neurons in both the utricular and saccular maculae, and trigger small electromyographic (EMG) responses [called vestibular-evoked myogenic potentials (VEMPs)] in various muscle groups throughout the body. The use of...

Maintaining Balance when Looking at a Virtual Reality Three-Dimensional Display of a Field of Moving Dots or at a Virtual Reality Scene.

Frontiers in neurology

Chiarovano E, de Waele C, MacDougall HG, Rogers SJ, Burgess AM, Curthoys IS.
PMID: 26284023
Front Neurol. 2015 Jul 27;6:164. doi: 10.3389/fneur.2015.00164. eCollection 2015.

EXPERIMENTAL OBJECTIVE: To provide a safe, simple, relatively inexpensive, fast, accurate way of quantifying balance performance either in isolation, or in the face of challenges provided by 3D high definition moving visual stimuli as well as by the proprioceptive...

Horizontal Eye Position Affects Measured Vertical VOR Gain on the Video Head Impulse Test.

Frontiers in neurology

McGarvie LA, Martinez-Lopez M, Burgess AM, MacDougall HG, Curthoys IS.
PMID: 25852637
Front Neurol. 2015 Mar 17;6:58. doi: 10.3389/fneur.2015.00058. eCollection 2015.

BACKGROUND/HYPOTHESIS: With the video head impulse test (vHIT), the vertical VOR gain is defined as (vertical eye velocity/vertical head velocity), but compensatory eye movements to vertical canal stimulation usually have a torsional component. To minimize the contribution of torsion...

The Skull Vibration-Induced Nystagmus Test of Vestibular Function-A Review.

Frontiers in neurology

Dumas G, Curthoys IS, Lion A, Perrin P, Schmerber S.
PMID: 28337171
Front Neurol. 2017 Mar 09;8:41. doi: 10.3389/fneur.2017.00041. eCollection 2017.

A 100-Hz bone-conducted vibration applied to either mastoid induces instantaneously a predominantly horizontal nystagmus, with quick phases beating away from the affected side in patients with a unilateral vestibular loss (UVL). The same stimulus in healthy asymptomatic subjects has...

Bleed-through correction for rendering and correlation analysis in multi-colour localization microscopy.

Journal of optics (2010)

Kim D, Curthoys NM, Parent MT, Hess ST.
PMID: 26185614
J Opt. 2013 Sep;15(9). doi: 10.1088/2040-8978/15/9/094011.

Multi-colour localization microscopy has enabled sub-diffraction studies of colocalization between multiple biological species and quantification of their correlation at length scales previously inaccessible with conventional fluorescence microscopy. However, bleed-through, or misidentification of probe species, creates false colocalization and artificially...

What galvanic vestibular stimulation actually activates.

Frontiers in neurology

Curthoys IS, Macdougall HG.
PMID: 22833733
Front Neurol. 2012 Jul 20;3:117. doi: 10.3389/fneur.2012.00117. eCollection 2012.

In a recent paper in Frontiers Cohen et al. (2012) asked "What does galvanic vestibular stimulation actually activate?" and concluded that galvanic vestibular stimulation (GVS) causes predominantly otolithic behavioral responses. In this Perspective paper we show that such a...
