Galvanic vestibular stimulation modulates the electrophysiological response during face processing.
Although galvanic vestibular stimulation (GVS) is known to affect the speed and accuracy of visual judgments, the underlying electrophysiological response has not been explored. In the present study, we therefore investigated the effect of GVS on the N170 event-related potential, a marker commonly associated with early visual structural encoding. To elicit the waveform, participants distinguish...
متن کاملHabituation to Galvanic Vestibular Stimulation during Gait
Balance requires the integration of proprioceptive, visual, and vestibular sensory inputs. Contributions from the vestibular system are increasingly important when other sensory signals are lacking or erroneous [1]. Galvanic vestibular stimulation (GVS), the application of a small electrical current across the mastoid processes, has been used to apply a stimulus to the vestibular system indepen...
متن کاملGalvanic Stimulation of the Vestibular Periphery in Guinea Pigs During
23 Irregular vestibular afferents exhibit significant phase leads with respect to angular velocity of 24 the head in space. This characteristic and their connectivity with vestibulospinal neurons 25 suggest a functionally important role for these afferents in producing the vestibulo-collic 26 reflex (VCR). A goal of these experiments was to test this hypothesis using weak galvanic 27 stimulatio...

et al., 2012). The sense of roll is consistent with a host of other studies using GVS (Fitzpatrick et al., 1994; Inglis et al., 1995; Day et al., 1997; Zink et al., 1997; Day and Cole, 2002; Scinicariello et al., 2002/2003; Wardman et al., 2003a,b; see Fitzpatrick and Day, 2004 for review). Modeled on this research, we used 2–3 mA currents in lightly anesthetized rats and found strong activatio...
متن کاملSomatosensory influence on postural response to galvanic vestibular stimulation.
We investigated how postural responses to galvanic vestibular stimulation were affected by standing on a translating support surface and by somatosensory loss due to diabetic neuropathy. We tested the hypothesis that an unstable surface and somatosensory loss can result in an increase of vestibulospinal sensitivity. Bipolar galvanic vestibular stimulation was applied to subjects who were standi...
