The disappearing hand: vestibular stimulation does not improve hand localisation

Bilateral vestibular stimulation does not improve visual hemineglect.

This work compared the effect of unilateral (right and left) and bilateral vestibular stimulation in a right-brain-damaged patient with neglect. Neglect was improved following left caloric vestibular stimulation, and worsened following right vestibular stimulation. On the other hand, no modification of neglect was observed after bilateral vestibular stimulation. These results support the idea t...

Multisensory disintegration and the disappearing hand trick

Figure 1: Mean maximum single rise in skin conductance in response to threatening stimuli. Left panel: SH baseline condition in which the hand was always visible. Central panel: In the CH condition, a black cloth covered the right hand so that it could be touched, but not seen. Right panel: in the DH condition the hand was absent from both vision and touch using the disappearing hand trick (see...

How vestibular stimulation interacts with illusory hand ownership.

Artificial stimulation of the peripheral vestibular system has been shown to improve ownership of body parts in neurological patients, suggesting vestibular contributions to bodily self-consciousness. Here, we investigated whether galvanic vestibular stimulation (GVS) interferes with the mechanisms underlying ownership, touch, and the localization of one's own hand in healthy participants by us...

Dual touch localisation on the hand dorsum

Vestibular stimulation does not diminish the desire for amputation.
