What Does Galvanic Vestibular Stimulation Actually Activate?
Luigi Galvani spent 20 years conducting experiments to demonstrate electrical conductivity of nerves and muscles before publishing his major treatise on the subject in 1791 (Galvani, 1791). His personal friend and professional nemesis Count Alessandro Volta held a respectful but opposing view, that nerve and muscle tissues simply serve as passive conductors, and he built the first “voltaic” bat...

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 کاملWhat Galvanic Vestibular Stimulation Actually Activates
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 conclusion does not follow from the evidence. The evidence from neurophysiology is very clear: galvanic stimulation activ...
متن کاملGalvanic 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 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...
