“…Neurophysiological studies in different animals showed that stimuli comparable to our STB mainly stimulate otolithic irregular afferents (Zhu et al 2011;Curthoys et al 2014). Moreover, STB engage the visual-vestibular cortex in human fMRI (Janzen et al 2008;Schlindwein et al 2008;Indovina et al 2014). We speculate that the non-physiological vestibular stimulation of STB disrupts the normal anticipation of gravity effects during visual self-motion by altering the integration of visual and vestibular signals in the brain, possibly in the visual-vestibular cortex.…”

“…Here we used loud STB during visually simulated self-motion on a roller coaster (Indovina et al 2013a, b) because these acoustic stimuli are known to excite otolith receptors in several animal species (Young et al 1977;Curthoys and Vulovic 2011;Zhu et al 2011;Curthoys et al 2014) and to engage PIVC and parietal operculum in human fMRI (Janzen et al 2008;Schlindwein et al 2008;Indovina et al 2014). We hypothesized that the non-physiological vestibular stimulation would selectively disrupt the anticipation of gravity effects during visual self-motion.…”

“…We hypothesized that the non-physiological vestibular stimulation would selectively disrupt the anticipation of gravity effects during visual self-motion. To control for aspecific auditory effects, we contrasted STB with WN that stimulates the cochlea and auditory cortex but does not stimulate the vestibular receptors and vestibular cortex (Janzen et al 2008;Schlindwein et al 2008;Indovina et al 2014). …”

Humans anticipate the effects of gravity during visually simulated self-motion in the vertical direction. Here we report that an artificial vestibular stimulation consisting of short-tone bursts (STB) suppresses this anticipation. Participants pressed a button upon entering a tunnel during virtual-reality roller coaster rides in downward or forward directions. In different trials, we delivered STB, pulsed white noise (WN), or no sound (NO). In the control conditions (WN, NO), participants responded earlier during downward than forward motion irrespective of true kinematics, consistent with the a priori expectation that downward but not forward motion is accelerated by gravity. STB canceled the difference in response timing between the two directions, without affecting overall task performance. Thus, we argue that vestibular signals play a role in the anticipation of visible gravity effects during self-motion.

“…For example, participants exposed to negative images detected better passive whole-body rotations [120 && ]. Neuroscientific evidence of an affective modulation of vestibular responses has been proposed [123]. I propose that there is a very promising line of research to develop in order to better understand the bidirectional links between emotion, social processing, and vestibular disorders.…”

In addition to 'balancing the body', the vestibular cortical network contributes to modulate space, body and self-awareness. Emerging evidence suggests that the vestibular network expands into dimensions of emotion processing, mental health, and social cognition. Here, the importance of connecting vestibular physiology, affective neuroscience, and social neuroscience to better understand the psychological aspects of vertigo in otoneurology is discussed.
