Abstract/Results: ABSTRACT:
Information from the vestibular peripheral organs in the inner ear is integrated with several other classes of signals about the body, generated by eyes, muscles and joints. The resulting signals provide a coherent sense of body posture and orientation in surrounding space.
In this project, the vestibular organs of healthy volunteers were stimulated non-invasively. Participants made judgements about sensory stimuli, bodily sensations, and the relation between the body and the environment both under vestibular stimulation, and under control conditions.
Our results revealed that the vestibular system influences bodily self-awareness in at least four ways. First, vestibular inputs influence primary processing of both touch and pain. This influence may involve multisensory regulation of gains in somatosensory cortical processing pathways. Second, vestibular inputs influence higher order somatosensory representation, namely the localisation of somatosensory stimuli onto a map of the body. They do not alter the “body image”, or knowledge about the spatial organisation of the body as a physical object. Third, vestibular inputs are crucial in maintaining the differentiation between the self and the world, particularly in coding the distance between one’s own body and external objects. Finally, vestibular stimulation affects the active relation with the external environment, by adjusting the balance between explorative behaviours, i.e. discovering new possibilities and varying choices, and stereotyped behaviours. Taken together our results confirmed that the vestibular system has a pervasive influence on several interactions between the organism and the environment, and also a constitutive influence on the representation of the body and self.

Galvanic vestibular stimulation influences randomness of number generation
Publication year: 2012

http://link.springer.com/article/10.1007/s00221-012-3302-6
Abstract/Results: ABSTRACT:
Successful interaction with the external environment requires a balance between novel or exploratory and routine or exploitative behaviours. This distinction is often expressed in terms of location or orientation of the body relative to surrounding space: functions in which the vestibular system plays an important role. However, the distinction can also be applied to novel versus repetitive production of any behaviour or symbol. Here, we investigated whether vestibular inputs contribute to the balance between novel and routine behaviours, independently of their effects on spatial orienting, by assessing effects of galvanic vestibular stimulation (GVS) on a random number generation task. Right-anodal/left-cathodal GVS, which preferentially activates the left cerebral hemisphere decreased the randomness of the sequence, while left-anodal/right-cathodal GVS, which preferentially activates the right hemisphere increased it. GVS did not induce any spatial biases in locations chosen from the number line. Our results suggest that vestibular stimulation of each hemisphere has a specific effect on the balance between novel and routine actions. We found no evidence for effects of non-specific arousal due to GVS on random number generation, and no evidence for effects on number generation consistent with modulation of spatial attention due to GVS.

Vestibular inputs modulate somatosensory cortical processing
Publication year: 2012

http://link.springer.com/article/10.1007%2Fs00429-012-0404-7
Abstract/Results: ABSTRACT:
The vestibular system is unique among the senses because of the entirely multisensory nature of its cortical projections. Neuroanatomical and neuroimaging studies show that vestibular stimulation activates somatosensory areas, and particularly the so-called parieto-insular vestibular cortex (PIVC) in the monkey, while deactivating visual areas. Further, recent psychophysical studies showed that vestibular stimulation facilitates detection of electrocutaneous stimuli, suggesting a vestibular-somatosensory perceptual interaction. However, the functional mechanism underlying this perceptual facilitation remains unclear. We therefore recorded somatosensory potentials evoked by left median nerve stimulation, before and immediately after left cold caloric vestibular stimulation (CVS), in a small-scale study of eight healthy volunteers. CVS selectively enhanced the N80 component recorded over both ipsilateral and contralateral somatosensory areas, without significantly affecting earlier or later components. Interestingly, the N80 component has been localised to the parietal operculum, which includes the human homologue of the monkey PIVC, and is thus a prime neuroanatomical candidate for vestibular-somatosensory convergence. As a control, we measured visual evoked potentials to reversing checkerboard patterns and found no effects of vestibular stimulation. This rules out explanations based on indirect effects of vestibular modulations, such as general arousal or supramodal spatial attention. We believe our results provide the first clue linking brain structure to function for the interaction between vestibular and somatosensory systems.

Abstract/Results: ABSTRACT:
The vestibular system processes information about head movement and orientation. No unimodal vestibular cortex has been identified in the mammalian brain. Rather, vestibular inputs are combined with many other sensory signals in the cortex. This arrangement suggests that vestibular input could influence processing in other sensory modalities. Here we show that vestibular stimulation differentially modulates two submodalities of the somatosensory system, increasing sensitivity to tactile input, and independently reducing sensitivity to nociceptive input. These modulations of touch and pain can clearly be distinguished from supramodal attentional effects of vestibular stimulation, because they are bilateral and operate in different directions. Outside the artificial conditions of laboratory stimulation, the vestibular system codes movements of the head, indicating a new relation between the body and the external world. We suggest the vestibular system participates in a form of sensory signal management, changing the balance between the various sensory systems as the relation between the body and the external environment changes. This sensory rebalancing may be a crucial element in the brain's capacity to reorient towards novel or salient features in the environment.

Abstract/Results: ABSTRACT:
The vestibular system has widespread interactions with multisensory cortical networks, including the somatosensory areas. Several clinical observations suggested that vestibular signals are essential to compute more abstract cognitive representations of the body. However, the existing literature is generally based on isolated reports. We aimed to provide both a theoretical framework, and an experimental method to investigate potential vestibular contributions to somatic cognition. Accordingly, we have investigated effects of galvanic vestibular stimulation (GVS) on the localisation of a stimulus on the skin of the hand (a process that we define as somatoperception) and on the implicit representation of the hand size and shape (involving a different process which we define as somatorepresentation). Vestibular input influenced the localisation of tactile stimuli on the hand: touches on the dorsum of the hand were perceived as shifted toward the wrist. The specific polarity of vestibular stimulation influences the localisation errors. Right anodal and left cathodal, which influences both cerebral hemispheres, induced a stronger localisation bias compared to left anodal and right cathodal GVS, which influences primarily the right hemisphere. Although our data confirmed previous findings that the body model of the shape of the hand is massively distorted, vestibular inputs do not contribute to these distortions. Our results suggest that vestibular input influences the registration of somatosensory input onto a map of the body (somatoperception), but does not influence stored knowledge about the spatial organisation of the body as a physical object (somatorepresentation).

How the vestibular system interacts with somatosensory perception: A sham-controlled study with galvanic vestibular stimulation
Publication year: 2013

http://www.sciencedirect.com/science/article/pii/S0304394013005934
Abstract/Results: ABSTRACT:
The vestibular system has widespread interactions with other sensory modalities. Here we investigate whether vestibular stimulation modulates somatosensory function, by assessing the ability to detect faint tactile stimuli to the fingertips of the left and right hand with or without galvanic vestibular stimulation (GVS). We found that left anodal and right cathodal GVS, significantly enhanced sensitivity to mild shocks on either hand, without affecting response bias. There was no such effect with either right anodal and left cathodal GVS or sham stimulation. Further, the enhancement of somatosensory sensitivity following GVS does not strongly depend on the duration of GVS, or the interval between GVS and tactile stimulation. Vestibular inputs reach the somatosensory cortex, increasing the sensitivity of perceptual circuitry.

Modulation of cortical responses to nociceptive stimuli by vestibular stimulation. A laser-evoked potentials study

Abstract/Results: ABSTRACT:
The vestibular system is unique among the senses because of the entirely multisensory nature of its cortical projections. Neuroanatomical and neuroimaging studies show that vestibular stimulation activates somatosensory areas, and particularly the so-called parieto-insular vestibular cortex (PIVC) in the monkey, while deactivating visual areas. This arrangement suggests that vestibular input could influence sensory processing in other sensory modalities. Human clinical studies reported dramatic perceptual changes following caloric vestibular stimulation (CVS), including transient remission of tactile imperception and chronic pain in brain-damaged patients. We recently observed in healthy participants that CVS decreases perceptual thresholds for touch, but increases thresholds for pain. These results suggested a direct role of vestibular inputs in multisensory interactions with touch and pain. Although an enhancement in the somatosensory evoked potentials (N80) has been demonstrated, the neural mechanisms underlying vestibular-induced analgesia remain unclear.
To address this issue we delivered nociceptive laser stimuli to the left hand dorsum before (‘Baseline’ condition) and immediately after left cold CVS (‘CVS’ condition), and recorded the corresponding brain responses (laser-evoked potentials, LEPs) together with the single-trial ratings of subjective pain intensity. To control for non-specific effects (e.g. time-dependent habituation) both LEPs and intensity ratings were also recorded one hour after CVS (‘Post’ condition).
A significant analgesic effect was induced by left CVS, as reported in lower pain ratings in ‘CVS’ compared to both ‘Baseline’ and ‘Post’ (p=0.016 and p=0.001, respectively). No differences in pain ratings were found between ‘Baseline’ and ‘Post’. Left CVS reduced the amplitude of standard LEP peaks, relative to ‘Pre’ and ‘Post’, both in the early time-window of the N1 wave (all p<0.01) and in the later time-windows of the N2 (all p<0.005) and P2 waves (all p<0.05). There were trends for habituation of the N2 and P2 peaks between 'Pre' and 'Post' conditions (p=0.06 and p=0.10, respectively).
These results provide the first evidence that left CVS reduces the cortical responses to nociceptive laser stimulation, including components localised to the primary somatosensory cortex. Thus, the vestibular system directly modulates activity in somatosensory pathways. This analgesic effect induced by left CVS could involve either subcortical gating of the nociceptive input, or by a direct modulation of evoked somatosensory cortex activity, by concurrent vestibular inputs to the same area.

Abstract/Results: ABSTRACT:
No unimodal vestibular cortex has been identified in the mammalian brain, yet vestibular input projects to several cortical areas. Therefore vestibular input could influence processing in other sensory modalities. We recently observed that caloric vestibular stimulation (CVS) decreases perceptual thresholds for touch, but increases thresholds for pain, suggesting a direct role of vestibular inputs in multisensory interactions with pain. The neural mechanisms of such vestibular-induced analgesia remain unclear. To address this issue we delivered nociceptive laser stimuli to the left hand dorsum before ('Baseline') and immediately after left CVS ('CVS'), and recorded the corresponding brain responses (laser-evoked potentials, LEPs) together with the single-trial ratings of subjective pain intensity. To control for non-specific effects (e.g. time-dependent habituation) both LEPs and intensity ratings were also recorded one hour after CVS ('Post'). CVS induced a significant analgesic effect, with lower pain ratings in 'CVS' compared to both 'Baseline' and 'Post' (p=0.016 and p=0.001, respectively). There were no differences in pain ratings between 'Baseline' and 'Post'. CVS reduced the amplitude of standard LEP peaks, relative to 'Pre' and 'Post', both in the early time-window of the N1 wave (all p< 0.01) and in the later time-windows of the N2 (all p< 0.005) and P2 waves (all p< 0.05). There were trends for habituation of the N2 and P2 peaks between ´Pre´ and ´Post´ conditions (p=0.06 and p=0.10, respectively). Thus, the most striking effect of the CVS was a strong reduction of cortical responses to nociceptive laser stimulation, including components localised to the primary somatosensory cortex. These results provide the first evidence that CVS modulates cortical responses elicited by nociceptive stimuli. The analgesic effect of CVS could involve either subcortical gating of the nociceptive input, or direct modulation of evoked somatosensory cortex activity, by concurrent vestibular inputs to the same area.

Abstract/Results: ABSTRACT:
AIM OF INVESTIGATION:
No unimodal vestibular cortex has been identified in the mammalian brain, yet vestibular input projects to several cortical areas. Therefore vestibular input could influence processing in other sensory modalities. We recently observed that caloric vestibular stimulation (CVS) decreases perceptual thresholds for touch, but increases thresholds for pain, thus suggesting a direct role of vestibular inputs in multisensory interactions with pain. The neural mechanisms of such vestibular-induced analgesia remain unclear.
METHODS:
To address this issue we delivered nociceptive laser stimuli to the left hand dorsum before ('Baseline' condition) and immediately after left CVS ('CVS' condition), and recorded the corresponding brain responses (laser-evoked potentials, LEPs) together with the single-trial ratings of subjective pain intensity. To control for non-specific effects (e.g. time-dependent habituation) both LEPs and intensity ratings were also recorded one hour after CVS ('Post' condition).
RESULTS:
CVS induced a significant analgesic effect, with lower pain ratings in 'CVS' compared to both 'Baseline' and 'Post' (p=0.016 and p=0.001, respectively). There were no differences in pain ratings between 'Baseline' and 'Post'. CVS reduced the amplitude of standard LEP peaks, relative to 'Pre' and 'Post', both in the early time-window of the N1 wave (all p<0.01) and in the later time-windows of the N2 (all p<0.005) and P2 waves (all p<0.05). There were trends for habituation of the N2 and P2 peaks between 'Pre' and 'Post' conditions (p=0.06 and p=0.10, respectively). Thus, the most striking effect of the CVS was a strong reduction of cortical responses to nociceptive laser stimulation, including components localised to the primary somatosensory cortex.
CONCLUSIONS:
These results provide the first evidence that CVS modulates cortical responses elicited by nociceptive stimuli. The analgesic effect of CVS could involve either subcortical gating of the nociceptive input, or a direct modulation of evoked somatosensory cortex activity, by concurrent vestibular inputs to the same area.

BIAL Foundation Archive
Start date: 1994
History:
The BIAL Foundation was created in 1994 by Laboratórios BIAL in conjunction with the Council of Rectors of Portuguese Universities. BIAL’s Foundation mission is to foster the scientific study of Man from both the physical and spiritual perspectives.
Along the years the BIAL Foundation has developed an important relationship with the scientific community, first in Portugal and after worldwide. Today it is an institution of reference which aims to stimulate new researches that may help people, promote more health and contribute to new milestones to gain access to knowledge.
Among its activities the BIAL Foundation manages the BIAL Award, created in 1984, one of the most important awards in the Health field in Europe. The BIAL Award rewards both the basic and the clinical research distinguishing works of major impact in medical research.
The BIAL Foundation also assigns Scientific Research Scholarships for the study of neurophysiological and mental health in people, arousing the interest of researchers in the areas of Psychophysiology and Parapsychology.
To date the BIAL Foundation has supported 461 projects, more than 1000 researchers, with research groups in twenty-seven countries, resulting, until April 2013, in about 600 full papers, out of which 172 published in indexed international journals with an average impact factor of 3.6 and a substantial number of citations (1665).
Since 1996 the BIAL Foundation organizes the Symposia entitled "Behind and Beyond the Brain", a Forum that gathers well renowned neurosciences speakers and the BIAL Foundation Fellows which are spread around the world.
Classified as an institution of public utility, the BIAL Foundation includes among its patrons the Portuguese President, the Portuguese Universities Rectors' Council and the Portuguese Medical Association.

Title: BIAL Grants
Start date: 1994
History:
In 1994 the BIAL Foundation launched a programme of science research grants with the aim of encouraging the research into Man’s physical and mental processes, namely in fields still largely unexplored but which warrant further scientific analysis, as Psychophysiology and Parapsychology.
Since its launch, applications to the BIAL grants have been increasing. Up to now 461 projects have been supported, involving more than 1000 researchers from 27 countries.
The approved applications have benefited from grants in amounts comprised between €5,000 and €50, 000. The amount to be granted is fixed by the Scientific board according to the needs of each project.
The supported projects have originated, until April 2013, in about 600 full papers, 172 out of which were published in indexed international journals with an average impact factor of 3.6 and a substantial number of citations (1665).
Among the BIAL Foundation fellows is worth highlighting the presence of scientists from prestigious universities from the United States, United Kingdom, Australia, Russia, Germany, Japan, France, Canada, and many others.
The BIAL grants are promoted biannually.

Reallocating the world. Vestibular contribution to distance perception

Abstract/Results: ABSTRACT:
Vestibular sensation is a truly enigmatic relative in the family of the human senses. Uniquely, it produces no conscious perceptions of its own, yet it is essential for all our interactions with the external environment. Clinical reports suggest that vestibular canal dysfunction leads to disintegration in the normal relation between personal and extrapersonal space (Blanke et al., 2004).Vestibular input occurs during head rotation to reorient towards a new part of external space. We investigated whether galvanic vestibular stimulation (GVS) interferes with a different form of spatial representation not directly coded by the canals, namely three-dimensional distance perception. Healthy supine participants judged the distance between their own body and an external object. Left anodal GVS produced misperception of distance: objects near the body were perceived as closer, and distant objects were perceived as farther away, relative to sham stimulation. In a further experiment, left anodal GVS lead to distance overestimation for farther sounds. This suggests that vestibular contributions to space perception are not merely driven by visuo-vestibular interactions,but imply a specific role of the vestibular system in supramodal space coding.The computation of object location from multiple sensory signals is fundamental for effective and direct action on the surroundings. We speculate that a vestibular-induced shift in space perception optimizes the sensitive pickup of information from personal space, and neglects the non-relevant ones located far away. Vestibular mediation of the relation between body and environment may play a fundamental role in selfawareness.
