Abstract:
Recent discoveries of visceral nociceptive inputs sharing the classical tactile pathway in the dorsal-column medial lemniscus system have opened a new venue for the investigation of somatovisceral interactions. The current study was designed to determine whether somatic innocuous inputs modulate visceral nociceptive transmission at the thalamic level. The investigation was carried out by means of extracellular single-unit recordings in the ventroposterior lateral nucleus of the thalamus in rats anesthetized with pentobarbital. Noxious visceral stimulation was achieved by reproducible colorectal distension (CRD, 20–80 mmHg) with a balloon catheter. Tactile stimulation was delivered by means of a feedback-controlled mechanical stimulator. The response of the neurons to CRD was compared before and after the conditioning procedure by giving tactile stimulation either immediately before CRD or overlapping it. Twenty-five ventroposterior lateral (VPL) thalamic neurons were found among numerous tactile-only neurons to have convergent inputs from both tactile and visceral sources. Their responses to CRD were excitatory (19), inhibitory (4), or bimodal. When cutaneous tactile stimuli were delivered before CRD, the responses were reduced in 18 cases. The reduction, however, was usually short-lasting, immediately following tactile stimulation and could not be enhanced by a prolonged conditioning procedure. It was unlikely to be attributable to neuronal habituation as the inverted procedure, CRD stimulation before tactile, often produced the opposite effect, that is, an enhanced response to skin stimulation. Repeated CRD could bring about sensitization of the responses of thalamic neurons as manifested by increased spontaneous discharge, lowered response threshold, and increased response level. Under such circumstances, the original effect of tactile stimulation on CRD responses could be weakened. In conclusion, tactile stimulation may in most circumstances inhibit thalamic neuronal responses to visceral nociceptive input produced by CRD. However, the effect appears to be mild and short-lasting at the individual neuronal level in the VPL thalamus.

Abstract:
Research has shown that the ability to integrate complementary sensory inputs into a unique and coherent percept based on spatiotemporal coincidence can improve perceptual precision, namely multisensory integration. Despite the extensive research on multisensory integration, very little is known about the principal mechanisms responsible for the spatial interaction of multiple sensory stimuli. Furthermore, it is not clear whether the size of spatialized stimulation can affect unisensory and multisensory perception. The present study aims to unravel whether the stimulated area’s increase has a detrimental or beneficial effect on sensory threshold. Sixteen typical adults were asked to discriminate unimodal (visual, auditory, tactile), bimodal (audio-visual, audio-tactile, visuo-tactile) and trimodal (audio-visual-tactile) stimulation produced by one, two, three or four devices positioned on the forearm. Results related to unisensory conditions indicate that the increase of the stimulated area has a detrimental effect on auditory and tactile accuracy and visual reaction times, suggesting that the size of stimulated areas affects these perceptual stimulations. Concerning multisensory stimulation, our findings indicate that integrating auditory and tactile information improves sensory precision only when the stimulation area is augmented to four devices, suggesting that multisensory interaction is occurring for expanded spatial areas.

Abstract:
Abstract Many social animals acquire social behaviours during development, and social experience during development can be vital for acquiring necessary social behaviours in adulthood. We investigated the development of a distinctive tactile interaction behaviour in Bronze Cory catfish, in which adults interact with one another tactilely during foraging and during group responses to threats. We found that larvae respond to applied tactile stimulation with a flight response significantly less often as larvae matured. This habituation to tactile stimulation is consistent with developing appropriate adult social behaviour. We also found that social exposure affects the larval response to tactile interactions with conspecifics, and that isolation in early life leads to a greater likelihood of responding to tactile interactions with conspecifics with a flight response. This suggests that social exposure is important for developing social tactile interaction behaviour and underscores the particular importance of early experience in social development.

Abstract:
Previous studies have shown that illusory ownership over a mannequin’s body can be induced through synchronous visuo-tactile stimulation as well as through synchronous visuo-vestibular stimulation. The current study aimed to elucidate how three-way combinations of correlated visual, tactile and vestibular signals contribute to the senses of body ownership and self-motion. Visuo-tactile temporal congruence was manipulated by touching the mannequin’s body and the participant’s unseen real body on the trunk with a small object either synchronously or asynchronously. Visuo-vestibular temporal congruence was manipulated by synchronous or asynchronous presentation of a visual motion cue (the background rotating around the mannequin in one direction) and galvanic stimulation of the vestibular nerve generating a rotation sensation (in the same direction). The illusory experiences were quantified using a questionnaire; threat-evoked skin-conductance responses (SCRs) provided complementary indirect physiological evidence for the illusion. Ratings on the illusion questionnaire statement showed significant main effects of synchronous visuo-vestibular and synchronous visuo-tactile stimulations, suggesting that both of these pairs of bimodal correlations contribute to the ownership illusion. Interestingly, visuo-tactile synchrony dominated because synchronous visuo-tactile stimulation combined with asynchronous visuo-vestibular stimulation elicited a body ownership illusion of similar strength as when both bimodal combinations were synchronous. Moreover, both visuo-tactile and visuo-vestibular synchrony were associated with enhanced self-motion perception; self-motion sensations were even triggered when visuo-tactile synchrony was combined with visuo-vestibular asynchrony, suggesting that ownership enhanced the relevance of visual information as a self-motion cue. Finally, the SCR results suggest that synchronous stimulation of either modality pair led to a stronger illusion compared to the asynchronous conditions. Collectively, the results suggest that visuo-tactile temporal correlations have a stronger influence on body ownership than visuo-vestibular correlations and that ownership boosts self-motion perception. We present a Bayesian causal inference model that can explain how visuo-vestibular and visuo-tactile information are combined in multisensory own-body perception.

Abstract:
Traditionally only speech communicates emotions via mobile phone. However, in daily communication the sense of touch mediates emotional information during conversation. The present aim was to study if tactile stimulation affects emotional ratings of speech when measured with scales of pleasantness, arousal, approachability, and dominance. In the Experiment 1 participants rated speech-only and speech-tactile stimuli. The tactile signal mimicked the amplitude changes of the speech. In the Experiment 2 the aim was to study whether the way the tactile signal was produced affected the ratings. The tactile signal either mimicked the amplitude changes of the speech sample in question, or the amplitude changes of another speech sample. Also, concurrent static vibration was included. The results showed that the speech-tactile stimuli were rated as more arousing and dominant than the speech-only stimuli. The speech-only stimuli were rated as more approachable than the speech-tactile stimuli, but only in the Experiment 1. Variations in tactile stimulation also affected the ratings. When the tactile stimulation was static vibration the speech-tactile stimuli were rated as more arousing than when the concurrent tactile stimulation was mimicking speech samples. The results suggest that tactile stimulation offers new ways of modulating and enriching the interpretation of speech.

Abstract:
This study examined the effects of tactile stimulation on self-injurious behaviour (SIB) in a 10-year-old boy with developmental disabilities. SIB occurred at high rates during unstructured play, suggesting an automatic reinforcement, sensory stimulation function. Noncontingent application of an alternative source of tactile stimulation produced only modest reductions in SIB, but contingent removal of the objects used to obtain tactile stimulation produced clinically significant reductions.

Abstract:
A soft, light-weight, beige, stuffed toy was placed in direct body contact with stable, 30-34 wk gestation infants. Length of hospitalization, l activity level, length of time to return to birth weight, and parent visiting rate were recorded for the randomly assigned 10 experimental and 10 control infants. Contrary to predictions, significant differences were found in the length of hospitalization and weight gain, with the control group being discharged sooner and returning to birth weight faster. No significant differences occurred in the parent visiting rate, and only minimal positive results were seen in the activity level for the experimental group. The disproportionate number of younger, smaller, sicker infants in the experimental group was believed to be a reason for these unexpected results.

Abstract:
The aim of this thesis was to examine fetal behavioural responses to auditory and tactile stimulation. Responses were examined for the second- and third-trimester fetuses (second-trimester ≤ 27 gestational weeks (wGA), third- trimester >27 wGA), in both experiments, respectively. Experiment 1 of this thesis examined fetal behavioural responses to the mother’s recorded and live voice, contrasting findings to an environmental sound and silent control conditions. Behavioural responses of 30 fetuses trimester (20-33 wGA, N = 13 in the 2nd and N = 17 in the 3rd trimester) Were examined in the following conditions were explored: (1) mother’s live, (2) and recorded voice, (3) an environmental sound, and (4) a silent control condition. Findings showed the strongest responses to maternal sounds as well as differential responses between gestational age groups. Younger fetuses displayed an arousal response to maternal voice, whereas third-trimester fetuses displayed an orientating response. The aim of Experiment 2 was to examine whether fetuses can differentiate between different human sources of tactile stimulation of the maternal abdomen. Behavioural responses of 28 fetuses (20-33 wGA, N = 15 in the 2nd and N = 13 in the 3rd trimester) were examined across four conditions: (1) mother’s, (2) father’s, and (3) stranger’s touch, as well as a (4) silent control condition. Differential responses to the tactile stimulation were found, especially in reaching of the uterine wall, and self- touch across the four conditions. Third- trimester fetuses touched the uterus wall for significantly longer than fetuses in the second-trimester. The strongest responses were found to the mother’s touch. Further differential responses were found between age groups, with third-trimester fetuses clearly differentiating between different sources of tactile stimulation, while second-trimester fetuses hardly showed differentiated responses. It is suggested that maturational differences in both experiments are due to the fetal development of the central nervous system, and might indicate the emergence of a proprioceptive self-awareness by the 3rd trimester.

Resumo: Peixes que apresentam relações de cooperação respondem a estimulação táctil (como massagens) reduzindo o estresse em uma interação entre cliente-limpador. Neste trabalho, nós testamos o efeito da estimulação táctil sobre a resposta ao estresse em um peixe territorial, a tilápia-do-nilo. Nós desenvolvemos um aparato formado de hastes verticais com cerdas de silicone nas laterais, que foi posicionado no meio do aquário, formando uma fileira de hastes. O peixe precisava passar pelas cerdas para acessar a comida (posicionada no lado oposto que o peixe se encontrava no aquário), recebendo assim a estimulação táctil. O estimulador foi eficiente, pois os peixes passaram espontaneamente pelo aparato na ausência de comida. Peixes isolados foram submetidos à estimulação táctil durante 7 dias e, em seguida, destinados a um dos dois tipos de estressor: não social (confinamento) e social (interação agressiva). Cada tratamento teve um controle sem o estimulador táctil. Após serem estressados os peixes aumentaram o número de atravessamentos pelas cerdas, que foi maior após o estresse social, sugerindo que eles buscaram pela estimulação táctil. Além disso, nós observamos que o número de iterações agressivas em duplas de machos diminuiu comparado ao controle. Entretanto, nós não observamos uma diminuição nos níveis de cortisol imediatamente após o estresse não social e social. Nós concluímos que a estimulação táctil aparentemente causa um efeito positivo no bem-estar de peixes territoriais...
Abstract: Cooperative fish respond to tactile stimulation (like massage) by reducing stress in a cleanerclient interaction. In this work, we tested the effect of tactile stimulation on the stress response of a territorial fish, Nile tilapia. We developed an apparatus formed by vertical sticks with silicone bristles in their sides, which was positioned in the middle of the aquarium, forming a row of sticks. Fish had to pass through bristled sticks to access food (placed in the opposite location of the fish in the aquarium), thus receiving tactile stimulation. The stimulator was efficient because fish pass through the apparatus spontaneously after trials, i.e. in the absence of feed. Isolated fish were submitted to the tactile stimulation during 7 days and afterwards they were assigned to one out of 2 types of stressors: non-social (confinement) and social stress (aggressive interaction). Each treatment had a control without the stimulator apparatus. After being stressed, fish increased the number of crosses in between the bristles, which was higher after social stress, suggesting fish sought for tactile stimulation. In addition, we observed that the number of aggressive interactions in male pairs decreased when compared to control. However, we did not observe a decrease in plasma cortisol levels immediately after stress either for social or non-social stress treatment. We conclude that tactile stimulation does not have an immediate effect on stress, but it reduces aggression in males of ...

Abstract:
This thesis examines both behavioral and anatomical effects of prenatal exposure of Valproic Acid (VPA) on Long Evans rats. Tactile stimulation (TS) is then used to investigate its’ effect on remediating any abnormalities VPA may produce. Several behavioral tests were done to assess the behavioral effects of VPA and TS. It was found that VPA had an effect of many of the tasks, whereas, TS had almost none with the exception of an effect on females in the elevated plus maze. However, anatomical data showed that TS had a profound effect on neuronal branch order, cell complexity, and spine density in pyramidal neurons in the medial prefrontal cortex, the orbitofrontal cortex and the amygdala. Where VPA decreased the above in all of these areas, TS increased neuronal complexity in the aforementioned structures. This study demonstrates that prenatal exposure to VPA is a viable model of autism in rats and that TS has significant anatomical effects in these animals as well as in control animals

Abstract:
Intensive care IS a stressful environment and this thesis addresses the controversy as to whether tactile stimulation can mitigate the negative influences in ventilated preterms. There is an underlying assumption throughout the thesis that the pre term infant in intensive care experiences and is able to manifest physical and/or psychological pain. Preterms (n=75) were recruited with parental consent against strict entry criteria. A pre-test, post-test time series, counterbalanced design was used to evaluate the impact of an intervention to alleviate pain. The intervention [Touching and Caressing, Tender in Caring (T AC-TIC)] was compared with a control condition (spontaneous activity). Indicators of pain represented in the experiments were immunologic, physiological, and neurobehavioural. Data were analysed using parametric and non-parametric tests. The ontogeny of the secretory Immune system was investigated (n=70) using an enzyme-linked immunosorbant assay for Secretory Immunoglobulin A (SIgA). Ventilated preterms had significantly lower SIgA than infants requiring no mechanical ventilation. Breast milk fed preterms showed increased SIgA compared to other modes of nutrition. TACTIC increased SIgA in a subsample of ventilated preterms (n=35) with no changes following the control condition. Cardiovascular responses remained stable throughout T AC-TIC and spontaneous activity. No changes in gastric pH were observed in a sub-sample of 18 preterms. A neurobehavioural checklist was used to analyse videos for pain and comfort behaviours (n=29). Significantly more comfort behaviours were reported during T AC-TIC. Analysis of behavioural state indicated that more time was spent inactive sleep during than after TAC-TIC. No differences In state occurred between TAC-TIC and control condition. A ventilated subsample (n=25) of the original cohort was subjected to analysis at individual level for determination of congruence between simultaneously measured outcome variables. T AC-TIC produced increases more often in two or three variables. Pilot work has also been conducted addressing further controversies in tactile stimulation. The results are discussed within the theoretical frameworks of Gottlieb's hierarchical systems model, and Adamson-Macedo's Equilibrium model

L'objectif de cette thèse est de proposer un périphérique tactile qui pourrait augmenter notre immersion dans un environnement virtuel en stimulant la pulpe du doigt. Ce dispositif s'inscrit dans le cadre des dispositifs haptiques. Ainsi, à partir d'une étude sur le rôle de la dynamique du toucher dans la perception de textures, nous avons proposé un dispositif tactile innovant permettant de simuler différentes textures fines. Dans cette thèse, fondamentalement pluridisciplinaire, nous avons d'abord déterminé les spécifications du cahier des charges pour obtenir un stimulateur tactile fonctionnel basé sur la génération d'un effet glissant. Après avoir identifié le phénomène responsable de cet effet glissant par vibration haute fréquence, nous avons réalisé le dimensionnement d'une plaque tactile capable de faire varier cet effet, c'est-à-dire de faire varier le coefficient de frottement perçu par l'utilisateur. Cette plaque est mise en vibration grâce à une matrice de céramiques piézoélectriques collées sur une ses faces. Ce dimensionnement a été validé par des simulations sur un logiciel d'éléments finis, puis la configuration retenue a été réalisée. Par la suite, le contrôle de la plaque vibrante nous a permis de moduler le coefficient de frottement perçu afin d'obtenir différents motifs. Dans une dernière partie, le périphérique a été évalué. Plusieurs textures crantées ont été testées afin de connaître les capacités des utilisateurs à différencier des périodes spatiales. Cette évaluation a permis de connaître les performances de ce stimulateur tactile et de comparer ses performances à celles d'une texture réelle.

Abstract:
Notre capacité à intégrer des informations venant de nos différents sens est fondamentale pour produire et réguler les mouvements de notre corps. L’objectif général de cette thèse est d’étudier les effets des déterminants de l’intégration multisensorielle sur nos comportements sensorimoteurs rythmiques. Les effets de l’intégration multisensorielle sur ce type de comportements sont peu connus car peu étudiés. Ces comportements caractérisent pourtant la majorité de nos activités quotidiennes comme marcher, écrire ou encore lors de la pratique d’activités sportives. Jusqu’à présent les processus multisensoriels ont été étudiés principalement dans le cadre de nos capacités de discrimination et de détection, révélant notamment la nécessaire synchronie temporelle entre les modalités pour leur intégration. Les conséquences de cette cohérence temporelle et des mécanismes associés n’ont jamais été testées sur les comportements sensorimoteurs rythmiques. Nous chercherons donc à généraliser leurs effets sur ces comportements. Par ailleurs, la littérature rapporte que les caractéristiques du mouvement modifient le traitement des informations sensorielles et semblent également influencer l’intégration multisensorielle. Nous testerons ainsi l’effet des caractéristiques de stabilité du système sensorimoteur, i.e. stabilité intrinsèque de la marche, sur l’intégration multisensorielle.Les deux contributions de cette thèse sont les suivantes : (1) Les comportements rythmiques obéissent aux mêmes principes que les comportements de discrimination temporelle ou de détection. Nos résultats généralisent les effets de cohérence temporelle et montrent pour la première fois l’effet de bénéfice multisensoriel sur la marche. (2) Nous formulons une hypothèse novatrice de compensation sensorimotrice, qui souligne l’utilisation adaptée des informations multisensorielles par le système sensorimoteur. Ce dernier compense la diminution de stabilité intrinsèque de la marche par une plus grande et/ou meilleure utilisation des informations externes audio-tactiles
Our ability to merge information coming from several senses is crucial to produce and regulate our body movements. The main objective of this thesis is to study the effects of multisensory integration factors on our sensorimotor rhythmic behaviours. The multisensory integration effects on these behaviours are not well understood, being seldom studied. However, those behaviours characterize most of our daily activities such as walking, writing or doing sports. So far, multisensory processes have essentially been studied with regard to our discrimination and detection skills, highlighting the necessity of a temporal synchrony between senses for their integration. The consequences of this temporal coherence and the associated mechanisms have never been tested on sensorimotor rhythmic behaviours. Thus, we will extend their effects to these behaviours. Besides, literature shows that the movements’ features modify the processing of sensory information and can influence multisensory integration. We will test the effects of the stability of the sensorimotor system, i.e. intrinsic stability of gait, on the multisensory integration.The two main contributions of the thesis are the following ones: (1) Rhythmic behaviours obey the same principles as temporal discrimination and detection behaviours. Our results generalize the effects of temporal coherence and show for the first time a multisensory benefit on gait. (2) We suggest a novel sensorimotor compensatory assumption, highlighting the adaptive use of multisensory information by the sensorimotor system, which compensates the decrease of the intrinsic stability of the gait with a larger and/or better use of external audio-tactile information

Abstract:
Un nouveau dispositif tactile capable d'enregistrer et de reproduire des scènes tactiles à l'aide de forces tangentielles a été conçu et réalisé sur la base des limites et des exigences du système somatosensoriel humain. Les micro-déformations tangentielles du doigt coulissant sur la texture sont mesurées par le transducteur dans une bande passante de 500Hz et sont reproduites par le déplacement d'une plaque de verre sous l'action contrôlée d'un moteur électrodynamique critiquement amorti. Dans le but d'évaluer la pertinence des signaux sensoriels pour la reproduction d'une scène tactile, les grandeurs physiques qui influent sur la perception tactile humaine ont été étudiées. En utilisant une méthode d'escalier, il a été démontré que des ondelettes avec différentes combinaisons d'amplitude et de durée sont ressenties égales en intensité. Ces résultats suggèrent qu'il existe des quantités physiques communes - des invariants - pour ces signaux auques le cerveau est sensible, ce qui pourrait se rapporter à une constance perceptuelle dans l'exploration d'aspérités. En analysant les forces de frottement créées par un doigt glissant sur une surface dotées de points braille à des vitesses différents, il a été constaté que, bien que la réponse mécanique instantanée varie dans son ensemble, l'intégrale des forces tangentielles locales au cours d'une période de déformation courte reste constante. Ces enregistrements ont ensuite été classés selon leur vitesse et utilisés comme stimuli dans une tâche de comparaison. Les participants devaient glisser leur index sur une plateforme de verre qui vibrait afin de reproduire les points brailles de hauteurs différentes enregistrés à la même
A new tactile device able to record and reproduce tactile scenes using tangential forces was designed and realized based on the limits and requirements of our somatosensory system. The tangential micro-deformations of the finger sliding on a textured surface can be measured with 500 Hz-bandwidth and reproduced by vibrating a glass plate under the controlled action of a critically damped electrodynamic actuator. In an effort to identify what sensory cues are relevant to tactile sensations for the reproduction of a scene, the physical quantities that influence tactile perception were studied. Using a staircase method, it was demonstrated that tactile wavelets with different combinations of amplitude and duration could be felt perceptually equal in intensity. These results suggested that there are common physical quantities – invariants – for these signals that the brain is sensitive to, which could relate to a perceptual constancy in asperity exploration. By analyzing the friction forces of a finger exploring braille dots with different pressures and velocities profiles, we found that although the mechanical response at a highly localized stimulus varies as a whole, the integral of the local tangential forces during a short deformation period remained constant. These recordings were then categorized by velocity and used as stimuli in a comparison task in which participants explored virtual dots of different heights at different speeds. While sliding on a glass platform which vibrated tangentially to reproduce a braille dot recorded at the same exploration speed, they were asked to report which of the two stimuli was stronger (or ‘higher’), a task that they could successfull

Abstract:
Le toucher joue un rôle prépondérant dans notre vie quotidienne. Il est connu depuis longtemps que l’acuité tactile peut être améliorée par effet de la plasticité cérébrale, suite à entraînement. Une autre forme d’amélioration, indépendante de l’entraînement, peut être obtenue grâce à une simple stimulation mécanique d’une petite région de la peau, appelée stimulation somatosensorielle répétée (RSS). Avant de commencer ce travail de thèse, il avait été montré que la RSS pouvait améliorer l’acuité tactile localement (sur le doigt stimulé) et aussi à distance (sur le visage) mais la topographie de l’amélioration tactile, notamment sur les autres doigts, demeurait inconnue. Également, l’hypothèse d’appliquer la RSS sur une autre région du corps (notamment le visage) et vérifier ses effets à la fois locaux sur le visage, ainsi qu’à distance sur les doigts, n’avait jamais été investiguée. Le but de mon travail de thèse constituait donc à investiguer la topographie de l’amélioration tactile induite par RSS au sein d’une même et entre plusieurs régions du corps. Une première étude a révélé que la RSS d’un doigt est capable d’induire une amélioration tactile locale ainsi qu’à distance entre les deux mains. La deuxième étude a prouvé que la RSS d’une région du visage est capable d’induire une amélioration tactile locale ainsi qu’une amélioration tactile à distance sur la main. De plus, l’effet d’amélioration tactile entre la main et le visage est bidirectionnel. Dans leur ensemble, les données expérimentales constituent une contribution significative à l'étude de la topographie des changements tactiles induits par la RSS
Touch plays a fundamental role in our daily activities. It has long been known that, thanks to brain plasticity, tactile acuity can be improved following training. Another form of tactile improvement, independent from training, can be achieved through a simple mechanical stimulation of a small region of the skin, called repetitive somatosensory stimulation (RSS). RSS of a finger was well known to improve tactile acuity locally (on the stimulated finger) and also remotely (on the face). However, topography of tactile improvement, especially on other unstimulated fingers, was unknown. In addition, the hypothesis of applying the RSS to another body region (notably the face) and investigate the possible effects, both in face and fingers, was not explored. The aim of this work of thesis was therefore investigating the topography of the RSS-induced tactile improvement within and between body regions. One first study revealed that RSS of a finger induces tactile improvement both locally and remotely in fingers. The second study showed that, when applied on the face, RSS is able to induce tactile improvement both locally, on the face, and remotely, in the hand, demonstrating that the tactile improvement between the hand and the face is bidirectional. Overall, the experimental data I provide constitute a significant contribution to the study of the topography of RSS-induced tactile changes

Abstract:
Sensory substitution and augmentation devices are built to try to replace or enhance one sense by using another sense. For example, in tactile–vision, stimulation of the skin driven by input to a camera is used to replace the ordinary sense of vision that uses our eyes. The feelSpace belt aims to give people a magnetic sense of direction using vibrotactile stimulation driven by a digital compass. This volume brings together researchers—neuroscientists, psychologists and philosophers—who are developing these technologies, studying the minds and behaviour of subjects who use them. There is a particular focus on the nature of the perceptual experiences, the sensory interactions, and the changes that take place in the mind and brain over time that occur while using and training to use these technologies. Essays address the nature, limits and possibilities of sensory substitution and augmentation, how they might be used to help those with sensory impairments, and what they can tell us about perception and perceptual experience in general.

Abstract:
AbstractElectrical stimulation is one of the methods to stimulate skin sensation, and can provide sensations such as vibration and pressure by changing the polarity of the stimulus. These stimuli can be combined to design a variety of tactile sensations. However, there is a major problem with electrical stimulation: As the amount of electric current is increased, itching or pain sensation is elicited. This study aims to suppress the itching and pain caused by electrical stimulation, and to present strong, clear, and stable, pressure and vibration sensations. We applied an anesthetic cream containing lidocaine, which is one of the most used local anesthetics, to reduce the induced pain and itching. Therefore, we specifically examine the applicability of lidocaine toward a desirable situation, in which pain thresholds are increased and tactile thresholds are not significantly affected. The results showed a significant relationship between the application of the cream and the dynamic range of stimulating current, and subsequently the quality of experience by human participants.

Abstract:
AbstractPrior research has shown that the direction of a user’s focus affects the perception of tactile cues. Additionally, user agency over touch stimulation has been shown to affect tactile perception. With the development of more complicated haptic and multi-sensory devices, simple tactile cues are rarely used in isolation and the effect of focus direction and of user agency on the perception of a sequence of tactile cues is unknown. In this study, we investigate the effect of both of these variables, focus direction and agency, on the perception of a cue sequence. We found that the direction of user focus and user sense of agency over tactile stimulation both had a significant effect on the accurate perception of a cue sequence. These results are presented in consideration for developing better haptic devices that account for users’ focus on and control over these devices.

Abstract:
AbstractTactile sharing with others facilitates improving communications and augmenting cooperative tasks. An increase of persons sharing tactile sensations increases the effectiveness whereas the area of tactile stimuli given should be investigated for intuitive perception. This study investigated the effect of spatial correspondence between tactile and visual stimuli in identifying tactile stimuli. In the experiment, participants viewed simultaneously two videos of other agents’ hands each rubbing one of three textures and felt their vibrotactile stimuli in two locations. The videos were presented at different locations on the screen (Scene 1$$:$$ : left-right side or Scene 2 & 3$$:$$ : top-bottom) and the vibrotactile stimuli were presented either at the wrists of the left and right hand (Scene 1) or at the upper arm and the wrist of the right arm which either rested on the table (Scene 2) or was hanging down along the body (Scene 3). For each scene, visual and tactile stimuli were either spatially aligned (left and right video with tactile stimuli at the left and right wrist, and top and bottom video with top and bottom location on the right arm) or not. The result showed shorter response times for left-right spatial correspondence and for far (top) and close (bottom) visual stimuli corresponding to distal (wrist) and proximal (upper arm) locations on the body. This implied that the body schematic is an important factor for spatial compatibility of visual and tactile stimuli.

Abstract:
The development of devices capable of delivering tactile and thermal feedback have the potential to improve brain-machine interfaces for neurorehabilitation protocols. Monetary rewards are known to improve some types of passive tactile processing. The aim of this study was to describe the performance and neural activity of subjects receiving tactile stimuli through a tactile stimulation sleeve in the presence or absence of monetary rewards. Healthy subjects were required to discriminate between different tactile stimulation patterns delivered through a stimulation sleeve while their neural activity was recorded with Electroencephalography (EEG). Behaviorally, no significant differences were observed in the performances of subjects wearing the sleeve. Meanwhile, analysis of neural activity revealed that the introduction of monetary rewards consistently generated significant differences in theta frequency band for occipital electrodes. These results support the notion that monetary rewards can significantly influence tactile information processing.

Abstract:
Abstract This study presents a new design of a wearable vibrotactile device — a tactile sleeve consisting of three voice coil actuators (Model: Lofelt L5). The device was made within an R&D project aimed at developing a wearable for enhancing the music perception of cochlear implant recipients. The aim is to provide tactile stimulation in addition to the cochlear implant stimulation — generating an audio-tactile music experience. We also present the results of an experiment performed to investigate whether the sleeve can be used to identify songs from tactile stimulation and investigate the effects of different encodings. Five short music segments were used, and the tactile stimulation provided by each voice coil actuator conveyed song information (Bass or drum). Participants had intact hearing. At the beginning of the experiment, the participants listened to one song via headphones. Afterward, they were presented with various tactile encodings of the songs in random order. Their task was to identify the encoding of the song that was played. In this experiment, an investigation of the best combination of information from the bass versus drums was conducted. The results confirm that the sleeve can provide tactile stimulation that can be used to identify songs without audio. The results also provide insights into which encodings are most useful for conveying music.
