“…This is in line with clinical observations that the perceived shape and size of the body and body parts might be modified in patients suffering from acute peripheral vestibular disorders (Bonnier, 1905;Yen Pik Sang et al, 2006) and that such modifications might also be evoked during artificial stimulations of the vestibular receptors (André et al, 2001;Le Chapelain et al, 2001;Yen Pik Sang et al, 2006). An interfering effect of vestibular stimulation with tactile mechanisms is further supported by neurons responding to both vestibular stimulation and tactile stimulation applied to the limbs.…”

“…Of pertinence for the present study, Bisiach et al (1991) described a patient suffering from somatoparaphrenia (this patient misidentified her left arm as belonging to her mother), whose abnormal ownership for her left arm was transiently normalized by caloric vestibular stimulation. In the same line, artificial stimulation of the peripheral vestibular system may modify the experience of phantom limbs in amputees and paraplegic patients (André, Martinet, Paysant, Beis, & Le Chapelain, 2001;Le Chapelain, Beis, Paysant, & Andre, 2001), strengthening the idea of an influence of vestibular processing on body part illusions. The contribution of vestibular cues to hand localization has not been specifically investigated in neurological patients, however, in healthy subjects, vestibular stimulation has been shown to induce errors during pointing movements to one's own hand (Bresciani et al, 2002;Mars, Archambault, & Feldman, 2003) and reproduction of arm positions (Knox, Coppieters, & Hodges, 2006).…”

a b s t r a c tArtificial 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 using the ''rubber hand illusion" paradigm. Our results show that left anodal GVS increases illusory ownership of the fake hand and illusory location of touch. We propose that these changes are due to vestibular interference with spatial and/or temporal mechanisms of visual-tactile integration leading to an enhancement of visual capture. As only left anodal GVS lead to such changes, and based on neurological data on body part ownership, we suggest that this vestibular interference is mediated by the right temporo-parietal junction and the posterior insula.

“…Thus, caloric vestibular stimulation modifies the experience of phantom limb sensations in paraplegic [80] and amputated [2] patients. These authors were able to evoke transient perceptions of phantom limbs in patients who did previously not experience such sensations suggesting a direct influence of vestibular processing on body part illusions.…”

Summary Body ownership and embodiment are two fundamental mechanisms of selfconsciousness. The present article reviews neurological data about paroxysmal illusions during which body ownership and embodiment are affected differentially: autoscopic phenomena (out-of-body experience, heautoscopy, autoscopic hallucination, feeling-of-a-presence) and the room tilt illusion. We suggest that autoscopic phenomena and room tilt illusion are related to different types of failures to integrate body-related information (vestibular, proprioceptive and tactile cues) in addition to a mismatch between vestibular and visual references. In these patients, altered body ownership and embodiment has been shown to occur due to pathological activity at the temporoparietal junction and other vestibular-related areas arguing for a key importance of vestibular processing. We also review the possibilities of manipulating body ownership and embodiment in healthy subjects through exposition to weightlessness as well as caloric and galvanic stimulation of the peripheral vestibular apparatus. In healthy subjects, disturbed self-processing might be related to interference of vestibular stimulation with vestibular cortex leading to disintegration of bodily information and altered body ownership and embodiment. We finally propose a differential contribution of the vestibular cortical areas to the different forms of altered body ownership and embodiment. Résumé L'attribution du corps propre et de ses éléments constitutifs (body ownership), ainsi que le sentiment d'incarnation (embodiment) -le fait d'habiter ce corps, d'être localisé dans les limites physiques de ce corps -, sont deux éléments fondamentaux de la conscience de soi. Nous faisons ici la synthèse de données issues de la neurologie montrant que des manifestations paroxystiques telles que les phénomènes autoscopiques (expérience de sortie du corps, héautoscopie, hallucination autoscopique, sensation de présence) et l'illusion de bascule de l'environnement (room tilt illusion) se caractérisent par une atteinte différentielle des mécanismes d'attribution du corps propre et du sentiment d'incarnation. Nous faisons l'hypothèse que les différents phénomènes autoscopiques et l'illusion de bascule de l'environnement se caractérisent par différents patrons de déficits d'intégration des informations sensorielles corporelles (informations visuelles, musculaires proprioceptives et tactiles) combinés à une perte de cohérence entre les références visuelles et vestibulaires. Chez les patients souffrant de phénomènes autoscopiques, les déficits d'attribution du corps propre et du sentiment d'incarnation ont été liés à un dysfonctionnement au niveau de la jonction temporopariétale et d'autres régions corticales recevant des informations vestibulaires, suggérant une contribution importante des afférences vestibulaires dans les mécanismes de la conscience de soi. Nous rapportons également des données de la littérature recueillies chez des sujets sains suggérant la possibilité de manipuler l'attribution ...

“…In some participants the symptoms completely disappeared while others only noticed a slight decrease, and the duration of the effect varied, lasting from only a few minutes to several days. Reduced pain after CVS has also been reported in amputees (André et al, 2001b) and paraplegics (Le Chapelain et al, 2001) with phantom limb pain -possibly mediated by a modification and normalization of the body schema by vestibular stimulation (see chapter 2.4. below). Further analgesic effects of CVS, which were still reported during follow-up several weeks later, were also found in two patients with central post-stroke pain (Ramachandran et al, 2007a(Ramachandran et al, , 2007b.…”

“…Chokron et al, 2007 for a review and a list of relevant studies), artificial vestibular stimulation has been used and suggested to be used as a therapeutic measure for patients with various bodily disorders. It has successfully been used to alleviate somatosensory hemi-inattention (Bottini et al, 2005;Schmidt et al, 2013), motor neglect (Vallar et al, 2003), anosognosia and personal neglect (Cappa et al, 1987), somatoparaphrenia (Rode et al, 1992), macrosomatognosia (Rode et al, 2012) as well as phantom limb sensation and pain (André et al, 2001a;Le Chapelain et al, 2001). Next to these positive (albeit not well-controlled findings), vestibular techniques have been enthusiastically propagated to treat a variety of other bodily disorders of both, neurological or psychiatric origin (Ramachandran et al, 2007a(Ramachandran et al, , 2007bRamachandran and McGeoch, 2007).…”

Although the discovery and understanding of the function of the vestibular system date back only to the 19th century, strategies that involve vestibular stimulation were used long before to calm, soothe and even cure people. While such stimulation was classically achieved with various motion devices, like Cox's chair or Hallaran's swing, the development of caloric and galvanic vestibular stimulation has opened up new possibilities in the 20th century. With the increasing knowledge and recognition of vestibular contributions to various perceptual, motor, cognitive, and emotional processes, vestibular stimulation has been suggested as a powerful and non-invasive treatment for a range of psychiatric, neurological and neurodevelopmental conditions. Yet, the therapeutic interventions were, and still are, often not hypothesis-driven as broader theories remain scarce and underlying neurophysiological mechanisms are often vague. We aim to critically review the literature on vestibular stimulation as a form of therapy in various selected disorders and present its successes, expectations, and drawbacks from a historical perspective.
