“…The sources of this vestibular alpha suppression are in line with the temporoparietal vestibular cortex previously identified (Bense et al 2001;Dieterich et al 2003;Hewett et al 2011;Kahane et al 2003;Lobel et al 1998;Lopez and Blanke 2011). Future work should distinguish how the present vestibular alpha oscillations compare to alpha oscillations over parietal regions previously linked to attentional (Haegens et al 2011(Haegens et al , 2012Romei et al 2008;Sauseng et al 2005) and related (i.e., Ferrè et al 2014;Figliozzi et al 2005) processes. Unlike studies of visual and somatosensory attention that showed a lateralization of alpha suppression (Haegens et al 2011(Haegens et al , 2012, we note that there was no significant difference between alpha suppression when comparing the early periods of CW and CCW rotation in study 2 and no lateralized topographies across all studies (Fig.…”

While there have been numerous studies of the vestibular system in mammals, less is known about the brain mechanisms of vestibular processing in humans. In particular, of the studies that have been carried out in humans over the last 30 years, none has investigated how vestibular stimulation (VS) affects cortical oscillations. Here we recorded high-density electroencephalography (EEG) in healthy human subjects and a group of bilateral vestibular loss patients (BVPs) undergoing transient and constant-velocity passive whole body yaw rotations, focusing our analyses on the modulation of cortical oscillations in response to natural VS. The present approach overcame significant technical challenges associated with combining natural VS with human electrophysiology and reveals that both transient and constant-velocity VS are associated with a prominent suppression of alpha power (8 -13 Hz). Alpha band suppression was localized over bilateral temporo-parietal scalp regions, and these alpha modulations were significantly smaller in BVPs. We propose that suppression of oscillations in the alpha band over temporo-parietal scalp regions reflects cortical vestibular processing, potentially comparable with alpha and mu oscillations in the visual and sensorimotor systems, respectively, opening the door to the investigation of human cortical processing under various experimental conditions during natural VS. EEG; vestibular processing; vestibular cortex THE VESTIBULAR SYSTEM encodes three-dimensional displacements of the head and its position relative to gravity. Vestibular signals are used for oculomotor and postural control but also underpin perceptual and cognitive functions, including visual perception according to internal models of gravity, spatial navigation, and bodily awareness (Brandt et al. 2005;Indovina et al. 2005;Lopez et al. 2010). In strong contrast with the growing number of functions shown to be under vestibular influence is the relative lack of data on the vestibular cortex in animals and humans (Angelaki and Cullen 2008;Brandt and Dieterich 1999;Lopez and Blanke 2011).Electrophysiological investigations in nonhuman primates have revealed vestibular responses in several areas of the cortex. These include the intraparietal sulcus and the somatosensory, temporal, frontal, and parieto-insular cortices (Bremmer et al. 2002;Grüsser et al. 1990aGrüsser et al. , 1990bGu et al. 2008;Liu et al. 2011;Schwarz and Fredrickson 1971). These areas form a cortical network of which the core is presumed to be located in the "parieto-insular vestibular cortex" (PIVC; Guldin and Grüsser 1998). Recently, descriptions of vestibular neurons' spatiotemporal tuning in these cortical regions have been achieved during three-dimensional passive rotations/ translations on motion platforms in nonhuman primates (e.g., Chen et al. 2011;Shinder and Newlands 2014;Takahashi et al. 2007).Investigations of the human vestibular cortex are challenging because neuroimaging techniques (fMRI, PET) do not allow head and body movements and thus the app...

“…If attention mediated vestibulo-tactile interactions, higher tactile sensitivity would be expected in the congruent condition with respect to the incongruent condition. Our results show improved tactile sensitivity during rotation, independently of congruency, as compared to the no-rotation baseline ( Figure 5, B) (Ferrè et al, 2014). Thus, natural vestibular stimulation improves tactile detection and this effect is independent of spatial attention.…”

Self motion perception involves the integration of visual, vestibular, somatosensory and motor signals. This article reviews the findings from single unit electrophysiology, functional and structural magnetic resonance imaging and psychophysics to present an update on how the human and non-human primate brain integrates multisensory information to estimate one’s position and motion in space. The results indicate that there is a network of regions in the non-human primate and human brain that processes self motion cues from the different sense modalities.

“…For completeness, the RHI and FBI are not only dissimilar from a conceptual point of view, but also from an empirical one—the RHI for instance is limited to a real hand to fake hand range of about 30 cm, while no finite range is known for the FBI. Similarly, while the vestibular system is an important component in bodily self‐consciousness (a sensory modality that is by default “global”), this sensory modality does not appear to strongly contribute to the RHI (but see Refs. and ), which instead importantly involves proprioceptive inputs.…”

Integrating information across sensory systems is a critical step toward building a cohesive representation of the environment and one's body, and as illustrated by numerous illusions, scaffolds subjective experience of the world and self. In the last years, classic principles of multisensory integration elucidated in the subcortex have been translated into the language of statistical inference understood by the neocortical mantle. Most importantly, a mechanistic systems-level description of multisensory computations via probabilistic population coding and divisive normalization is actively being put forward. In parallel, by describing and understanding bodily illusions, researchers have suggested multisensory integration of bodily inputs within the peripersonal space as a key mechanism in bodily self-consciousness. Importantly, certain aspects of bodily self-consciousness, although still very much a minority, have been recently casted under the light of modern computational understandings of multisensory integration. In doing so, we argue, the field of bodily self-consciousness may borrow mechanistic descriptions regarding the neural implementation of inference computations outlined by the multisensory field. This computational approach, leveraged on the understanding of multisensory processes generally, promises to advance scientific comprehension regarding one of the most mysterious questions puzzling humankind, that is, how our brain creates the experience of a self in interaction with the environment.
