“…Before and after the visuotactile stimulation, subjects were able to see the reflection of the ruler in the mirror and indicated the felt location of their right (stimulated) hand by verbally reporting the corresponding number on the ruler. The difference between the positions where the subjects localized their hands before and after the visuotactile stimulation indicated the condition-related proprioceptive drift (Lopez et al, 2010). The onsets of the ruler referred to different points and varied across conditions.…”

During mental rotation (MR) of body parts, people internally simulate the movement of their corresponding body segments. These sensory-motor mechanisms render MR sensitive to proprioceptive information (e.g., posture). Similar mechanisms can alter illusory hand ownership following synchronous visuotactile stimulation (e.g., the rubber hand illusion [RHI]). In the present study, we first showed that illusory ownership for a fake hand can also be induced when the posture of the fake hand (palm-up) does not correspond with the subject's physical hand posture (palm-down). Then we tested whether illusory ownership for a fake hand in such a posture impacts the MR of hands carried out immediately and repeatedly after the RHI. The results showed that MR was altered for the view corresponding to the fake hand's posture, but not for other views. Additionally, these effects depended on illusory ownership, as only synchronous visuotactile stimulation was found to lead to these changes, characterized by a modulation of the rotation-dependent profile of MR response times. These findings show that similar sensory-motor mechanisms are recruited during the MR of hands and illusory hand ownership manipulated through multisensory mismatch, and that bottom-up visuotactile stimulation interferes with highlevel imagery processes.

“…Rubber hand illusion Subjects were seated in front of a device specifically designed to induce the RHI (Lopez, Lenggenhager, & Blanke, 2010). The device was placed on a table in front of the subjects, at the midchest level, and consisted of a wooden frame with a two-way mirror on the top plane and a flat surface as the bottom plane.…”

“…The description of the anatomy and function of the vestibular cortex is thus not only necessary for systems neuroscience, but should also further our understanding of clinical aspects of vestibular disorders and the role of the vestibular cortical system in perception, cognition, and consciousness. The vestibular system has been involved in a variety of perceptive and cognitive functions based on behavioral effects reported after caloric or galvanic vestibular stimulation in healthy humans (Lenggenhager et al, 2008;Lopez and Blanke, 2007;Lopez et al, 2010b;Miller and Ngo, 2007), and such stimulation may have beneficial effects on deficits regarding external and corporeal space in brain-damaged patients (Bottini et al, 1995;McGeoch et al, 2008;Vallar et al, 1993).…”

The vestibular system provides the brain with sensory signals about three-dimensional head rotations and translations. These signals are important for postural and oculomotor control, as well as for spatial and bodily perception and cognition, and they are subtended by pathways running from the vestibular nuclei to the thalamus, cerebellum and the "vestibular cortex."The present review summarizes current knowledge on the anatomy of the thalamocortical vestibular system and discusses data from electrophysiology and neuroanatomy in animals by comparing them with data from neuroimagery and neurology in humans. Multiple thalamic nuclei are involved in vestibular processing, including the ventroposterior complex, the ventroanterior-ventrolateral complex, the intralaminar nuclei and the posterior nuclear group 2 0 1 1 ) 1 1 9 -1 4 6 Abbreviations: 3aHv, 3a-hand-vestibular area; 3aNv, 3a-neck-vestibular area; ASS, anterior suprasylvian cortex; DVN, descending vestibular nucleus; FEF, frontal eye fields; Ig, insula granularis; IL, intralaminar nuclei; LD, lateral dorsal nucleus; LGN, lateral geniculate nucleus; LP, lateral posterior nucleus; LVN, lateral vestibular nucleus; MGmc, medial geniculate nucleus, pars magnocellularis; MGN, medial geniculate nucleus; MIP, medial intraparietal area; MST, medial superior temporal area; MT, middle temporal area; MVN, medial vestibular nucleus; PIVC, parieto-insular vestibular cortex; PO, posterior group of the thalamus; Reipt, area retroinsularis pars parietalis; Ri, area retroinsularis; SGN, suprageniculate nucleus; SVN, superior vestibular nucleus; TPJ, temporo-parietal junction; VA, ventroanterior thalamic nucleus; Vim, nucleus ventralis intermedius; VIP R A I N R E S E A R C H R E V I E W S 6 7 (

“…Our data reveal that passive own body displacements due to vestibular stimulation systematically modulate bistable perception, which is in line with the functional importance of integrating vestibular with visual motion information (Young et al 1973;Buttner and Henn 1981). A more recent line of work has started investigating the effects of vestibular signals on mental imagery (Lenggenhager et al 2008) and other aspects of cognition (Berthoz et al 1995) as well as bodily self-consciousness (Lopez et al 2009(Lopez et al , 2010Ferre et al 2011;Ionta et al 2011). The present study extends the latter line of research showing that lowlevel vestibular signals regarding self-motion influence mechanisms of visual consciousness that are further modulated by the type of bistable object that is seen.…”

“…As vestibular stimulation has been shown to modulate perceptual, cognitive, and conscious aspects of bodily processing (Lenggenhager et al 2008;Lopez et al 2009Lopez et al , 2010Ferre et al 2011), we here investigated whether observer motion, conveyed by vestibular signals, modulates the perception of bistable moving human bodies. Given the functional importance of integrating vestibular with visual motion information for self-motion perception and the prominent neural interactions between vestibular and visual motion processing (e.g., Chowdhury et al 2009;Liu and Angelaki 2009), one may expect that vestibular information may also influence bistable visual motion perception of human bodies.…”

In two experiments we investigated whether bistable visual perception is influenced by passive own body displacements due to vestibular stimulation. For this we passively rotated our participants around the vertical (yaw) axis while observing different rotating bistable stimuli (bodily or non-bodily) with different ambiguous motion directions. Based on previous work on multimodal effects on bistable perception, we hypothesized that vestibular stimulation should alter bistable perception and that the effects should differ for bodily versus non-bodily stimuli. In the first experiment, it was found that the rotation bias (i.e., the difference between the percentage of time that a CW or CCW rotation was perceived) was selectively modulated by vestibular stimulation: the perceived duration of the bodily stimuli was longer for the rotation direction congruent with the subject's own body rotation, whereas the opposite was true for the non-bodily stimulus (Necker cube). The results found in the second experiment extend the findings from the first experiment and show that these vestibular effects on bistable perception only occur when the axis of rotation of the bodily stimulus matches the axis of passive own body rotation. These findings indicate that the effect of vestibular stimulation on the rotation bias depends on the stimulus that is presented and the rotation axis of the stimulus. Although most studies on vestibular processing have traditionally focused on multisensory signal integration for posture, balance, and heading direction, the present data show that vestibular self-motion influences the perception of bistable bodily stimuli revealing the importance of vestibular mechanisms for visual consciousness.
