Abstract:
Objectives. To determine (1) whether intramuscular adipose tissue (IntraMAT) differs between women with and without type 2 diabetes and (2) the association between IntraMAT and mobility and strength.Methods. 59 women ≥ 65 years with and without type 2 diabetes were included. A 1-Tesla MRI was used to acquire images of the leg. Timed-up-and-go (TUG) and grip strength were measured. Regression was used to determine associations between the following: (1) type 2 diabetes and IntraMAT (covariates: age, ethnicity, BMI, waist : hip ratio, and energy expenditure), (2) IntraMAT and TUG (covariates: diabetes, age, BMI, and energy expenditure), and (3) IntraMAT and grip strength (covariates: diabetes, age, height, and lean mass).Results. Women with diabetes had more IntraMAT. After adjustment, IntraMAT was similar between groups (diabetes mean [SD] = 13.2 [1.4]%, controls 11.8 [1.3]%,P=0.515). IntraMAT was related to TUG and grip strength, but the relationships became nonsignificant after adjustment for covariates (difference/percent IntraMAT [95% CI]: TUG = 0.041 seconds [−0.079–0.161],P=0.498, grip strength = −0.144 kg [−0.335–0.066],P=0.175).Conclusions. IntraMAT alone may not be a clinically important predictor of functional mobility and strength; however, whether losses in functional mobility and strength are promoted by IntraMAT accumulation should be explored.

Abstract:
AbstractApparent motion can occur within a particular modality or between modalities, in which a visual or tactile stimulus at one location is perceived as moving towards the location of the subsequent tactile or visual stimulus. Intramodal apparent motion has been shown to be affected or 'captured' by information from another, task-irrelevant modality, as in spatial or temporal ventriloquism. Here we investigate whether and how intermodal apparent motion is affected by motion direction cues or temporal interval information from a third modality. We demonstrated that both moving and asynchronous static sounds can capture intermodal (visual–tactile and tactile–visual) apparent motion; moreover, while the auditory direction cues have less impact upon the perception of intramodal visual apparent motion than upon the perception of intramodal tactile or intermodal visual/tactile apparent motion, the auditory temporal information has equivalent impacts upon both intramodal and intermodal apparent motion. These findings suggest intermodal apparent motion is susceptible to the influence of dynamic or static auditory information in similar ways as intramodal visual or tactile apparent motion.

El propósito de este estudio es evaluar el priming intramodal del gusto e intermodal entre el gusto y la visión. Los datos mostraron una facilitación en el reconocimiento de los estímulos estudiados en relación con los estímulos nuevos en el experimento de priming intramodal. En el experimento de priming intermodal, el reconocimiento de los estímulos estudiados no se diferenció significativamente del reconocimiento de los estímulos nuevos. En ambos estudios, los resultados mostraron que el tiempo de procesamiento requerido para los estímulos estudiados es menor que para los estímulos nuevos, y se observó una correlación inversa entre esta variable y el reconocimiento. Se concluye la presencia de priming intramodal del gusto e intermodal entre el gusto y la visión.

Abstract:
The study investigated the contribution of kinesthetic and visual input to the performance of reaching movements and identified rules governing the transformation of information between these two sensory modalities. The study examined the accuracy by which 39 subjects reproduced locations of five targets in a horizontal plane. Mode of target presentation and feedback during reproduction of a target's location was either visual, kinesthetic or a combination of both modalities. Thus, it was possible to examine performance when target presentation and reproduction involved feedback from the same sensory modality (intramodal) as well as from different sensory modalities (intermodal). Errors in target reproduction were calculated in terms of distance and systematic biases in movement extent. The major findings of the study are (1) Intramodal reproduction of a target's location on the basis of kinesthetic feedback is somewhat less accurate than intramodal reproduction on the basis of visual feedback. (2) Intermodal performance is significantly less accurate than intramodal performance. (3) Accuracy of performance does not depend on the direction of information transfer between sensory modalities. (4) Intermodal performance is characterized by systematic biases in extent of movement which are dependent on the direction of information transfer between modalities. (5) When presentation of the target's location is bimodal, reproduction is adversely affected by the conflicting input. The results suggest that transformation rules, used to combine input from various sensory modalities, depend on environmental conditions and attention.

Abstract:
The use of spatial stimulus features seems to facilitate both intramodal and crossmodal temporal order judgments (TOJ). For example, TOJ between two tactile stimuli are easier when the two stimulated hands are held far apart rather than close together (Shore et al., 2005), suggesting automatic coding of tactile location in external coordinates. Similarly, performing a TOJ between two stimuli from different modalities is easier when the two stimuli are separated in space (Spence et al., 2003). We have previously shown that use of spatial features for intramodal TOJ becomes evident by the age of six years (Pagel et al., 2009). Here, we tested whether the advantage of spatial separation in crossmodal comparisons is observable at the same age. Fifty-nine children between 4 and 12 years as well as 13 young adults performed a modality TOJ task for simple tactile and visual stimuli. Stimuli were presented either within the same or in different hemifields. Spatial separation improved TOJ performance only for children aged 10 years and older. However, crossmodal TOJ performance was worse than intramodal TOJ performance starting at the age of 6 years. Crossmodal TOJ performance comparable to adults was not observed before the age of 12 years. We speculate that the ability to redundantly code sensory input in modality-specific and supramodal (external) spatial coordinates facilitates intramodal temporal processing. Further refinement of the processes providing external spatial coordinates (e.g., touch remapping) then results in integrated use of space and time allowing for more precise assignment of sensory inputs to the same or to different events.

Abstract:
Dans une première partie, une présentation succinte de la maladie d’Alzheimer et de ses différentes stratégies thérapeutiques est rappelée. La conception de décalines et de pipéridines fonctionnalisées, et l’évaluation de leurs propriétés anticholinestérasiques, antiinflammatoires et neuroprotectrices est ensuite présentée. Concernant les décalines, la synthèse du composé cle�� 3,7-dinitro-11-oxa-tricyclo[6. 2. 1. 01. 6]undec-9-ene est détaillée. S’ensuit la présentation des différents types de réactions engagées à partir de ce synthon en vue de l’obtention de composés bioactifs, notamment les réactions d’ouverture de l’endoxyde (première série), puis les autres réactions considérants les fonctions nitro et la double liaison (seconde série). Les pipéridines fonctionnalisées dérivent quant à elle de la lactone de l’acide 4-hydroxypipécolique. Deux voies générales d’ouverture de cette lactone sont exposées : une réaction de type Wittig sur l’aldol, ou bien une attaque nucléophile ; afin d’introduire une chaîne fonctionnalisée et d’ouvrir un accès à de nouvelles séries bicycliques. Les principaux résultats biologiques de ces composés sont également présentés. Une seconde partie concerne la synthèse d’acridones à visée antitumorales analogues simplifiés des furanoacridones précédemment développés au laboratoire. L’évaluation biologique de cette première série de composés a en effet montré le caractère hautement actif de la fonction époxyde portée par un cycle furanique accolé aux chromophores acridoniques. L’allylation des noyaux 1,3-dihydroxyacridoniques puis leur fonctionnalisation en époxydes a été réalisée. L’évaluation de leurs propriétés antitumorales in vitro est présentée
The first part of this work recalls a general introduction for Alzheimer Disease and its treatments. Functionalized decalins and piperidines compounds have been synthesized and their anticholinesterasic, anti-inflammatory and neuroprotective properties were evaluated. Synthetic approaches to decalins and their synthesized derived from the key compound 3,7-dinitro-11-oxa-tricyclo [6. 2. 1. 01. 6] undec-9-ene, is described. Different types of reactions towards bioactive compounds, including the endoxyde opening reactions (first series), and other reactions to functionalize the nitro group and the double bond (second series) are developed. Regarding the synthesis of functionalized piperidines derived from the lactone of 4-hydroxypipecolic acid, two general pathways for lactone ring-opening are investigated. For a first serie of compounds a Wittig type reaction on the corresponding lactol is considered. For the second serie, a nucleophilic attack on the lactone is considered to introduce a functionalized chain. This work opens access to new bicyclic series. In a second part of this work, the synthesis of simplified acridones derived from the highly cytotoxic furanic parent compounds is described: O-allylation and functionalization into epoxides and esters of 1,3-dihydroxyacridones. Evaluation of their antitumor properties is also well presented

Abstract:
The aim of this study was to investigate the intra- and intermodal impact of different kinds of early sensory experience on the development of specific neural/perceptual systems. The manipulations of the rats' early experience involved a combination of early binocular deprivation through dark-rearing, somatosensory restriction through cauterization of mystacial vibrissae, and multimodal enrichment through rearing in a complex environment. Specific lesions to somatosensory (Parl) and visual (Oc2M) cortex in differentially reared animals were included in an attempt to gain further insight into the plasticity surrounding manipulations of early stimulation history. Five tasks were used to assess these effects of early rearing condition in combination with later cortical lesions. Behavioral assessment focused on the ability of the animals to encode, abstract, and remember specific relationships between stimuli within the deprived modality itself, their ability to do so with information presented in other modalities, and on the basic species specific behavior. The only effect found was a main effect for rearing condition. Basically, complex-reared rats were more competent on several of the behavioral tasks than were dark-reared rats. However, this result provided little behavioral support for ideas of modality interdependence. Dendritic proliferation is considered to be a general mechanism supporting behavioral change. The subsequent neuroanatomical assessment focused on dendritic branching of neurons in specific cortical areas thought to be most affected by early environmental manipulations. Animals that were raised in a complex environment, but had experienced early tactile restriction through cauterization of vibrissae, showed significantly more dendritic branching than animals from all other rearing conditions in all cortical areas measured. This finding is consistent with ideas of both intra- and intermodal compensation following damage to an early developing modality, as well as behavioral demand acting as a significant factor in determining the impact of early somatosensory restriction. It is reasonable to assume that anatomical changes should be manifested behaviorally. Suggestions for smaller, more restricted studies, that would be more effective in describing the behavioral impact of early manipulations of the environment, were outlined.

Abstract:
Despite the extensive work done on the neural consequences of tactile restriction very little is known about the behavioural consequences of this manipulation. In the present investigation, an assessment was made of the effects of early, long-term tactile restriction by bilateral removal of the mystacial vibrissae on the subsequent somatosensory capacities of rats (i.e. the intramodal consequences) as well as its effects on visual and spatial capacities (i.e. the intermodal consequences). As well, rearing environment (enriched vs. normal) and type of surgery (vibrissae removal by cauterization of follicles or by plucking) were examined to determine specific factors that might influence the effect of early, long-term vibrissae removal. Five tasks were used to assess these effects. The first two tasks assessed the intermodal consequences of vibrissae removal. Visual competence was assessed by measuring the habituation of orientation to repeated visual stimuli and the dishabituation to subtle changes in these stimuli. A version of the Morris (1981) water maze was used to assess the rats' spatial abilities. The results of these two tasks revealed limited evidence for intermodal effects. In terms of habituation to visual orientation, rats that had had their vibrissae removed by cauterization and were subsequently reared with daily access to an enriched environment required more trials to habituate to the presentation of repeated visual stimuli. As well, these rats were the only group to dishabituate to a subtle change in the stimuli. No effect of vibrissae removal was found in the spatial task, and environmental enrichment during development enhanced performance on this task, apparently through increased attention to distal cues by rats reared in this condition. The remaining three tasks assessed the motoric and somatosensory effects of tactile restriction. No effect was found on the performance of the Puzzle Latch Box test in which the rats were required to manipulate various latches to obtain a food reward. As well, no significant effect was observed in reactions to the tying of pieces of wire to the rats' wrists. However, early, long-term vibrissae removal (by cauterization of follicles or by plucking) attenuated orientation to contacts of the mystacial pad itself. This effect was dissociated from tactile reactivity; all rats exhibited eye-flinch responses to taps on this area. These results suggest that early, long-term tactile restriction has significant behavioural consequences for the somatosensory system as well as the visual system. These data also provide limited evidence for theories of modality interdependence as well as yielding basic information concerning the role of the mystacial vibrisse in the behaviour of the rat.

Abstract:
Challenges arising from an increasing traffic demand, limited resource availability and growing quality expectations of the customers can only be met successfully, if each transport mode is regarded as an intelligent transportation system itself, but also as part of one intelligent transportation system with “intelligent” intramodal and intermodal interfaces. This topic is well reflected in the Third International Conference on “Models and Technologies for Intelligent Transportation Systems” which took place in Dresden 2013 (previous editions: Rome 2009, Leuven 2011). With its variety of traffic management problems that can be solved using similar methods and technologies, but with application specific models, objective functions and constraints the conference stands for an intensive exchange between theory and practice and the presentation of case studies for all transport modes and gives a discussion forum for control engineers, computer scientists, mathematicians and other researchers and practitioners. The present book comprises fifty short papers accepted for presentation at the Third Edition of the conference. All submissions have undergone intensive reviews by the organisers of the special sessions, the members of the scientific and technical advisory committees and further external experts in the field. Like the conference itself the proceedings are structured in twelve streams: the more model-oriented streams of Road-Bound Public Transport Management, Modelling and Control of Urban Traffic Flow, Railway Traffic Management in four different sessions, Air Traffic Management, Water Traffic and Traffic and Transit Assignment, as well as the technology-oriented streams of Floating Car Data, Localisation Technologies for Intelligent Transportation Systems and Image Processing in Transportation. With this broad range of topics this book will be of interest to a number of groups: ITS experts in research and industry, students of transport and control engineering, operations research and computer science. The case studies will also be of interest for transport operators and members of traffic administration.

Abstract:
The aim of this paper is to evaluate the performance of two divergent methods for delineating commuting regions, also called labour market areas, in a situation that the base spatial units differ largely in size as a result of an irregular population distribution. Commuting patterns in Sweden have been analyzed with geographical information system technology by delineating commuting regions using two regionalization methods. One, a rule-based method, uses one-way commuting flows to delineate local labour market areas in a top-down procedure based on the selection of predefined employment centres. The other method, the interaction-based Intramax analysis, uses two-way flows in a bottom-up procedure based on numerical taxonomy principles. A comparison of these methods will expose a number of strengths and weaknesses. For both methods, the same data source has been used. The performance of both methods has been evaluated for the country as a whole using resident employed population, self-containment levels and job ratios for criteria. A more detailed evaluation has been done in the Goteborg metropolitan area by comparing regional patterns with the commuting fields of a number of urban centres in this area. It is concluded that both methods could benefit from the inclusion of additional control measures to identify improper allocations of municipalities.

Abstract:
En raison de l’utilisation d’un mode de communication totalement différent de celui des entendants, le langage des signes, et de l’absence quasi-totale d’afférences en provenance du système auditif, il y a de fortes chances que d’importantes modifications fonctionnelles et structurales s’effectuent dans le cerveau des individus sourds profonds. Les études antérieures suggèrent que cette réorganisation risque d’avoir des répercussions plus importantes sur les structures corticales situées le long de la voie visuelle dorsale qu’à l’intérieur de celles situées à l’intérieur de la voie ventrale. L’hypothèse proposée par Ungerleider et Mishkin (1982) quant à la présence de deux voies visuelles dans les régions occipitales, même si elle demeure largement acceptée dans la communauté scientifique, s’en trouve aussi relativement contestée. Une voie se projetant du cortex strié vers les régions pariétales postérieures, est impliquée dans la vision spatiale, et l’autre se projetant vers les régions du cortex temporal inférieur, est responsable de la reconnaissance de la forme. Goodale et Milner (1992) ont par la suite proposé que la voie dorsale, en plus de son implication dans le traitement de l’information visuo-spatiale, joue un rôle dans les ajustements sensori-moteurs nécessaires afin de guider les actions. Dans ce contexte, il est tout à fait plausible de considérer qu’un groupe de personne utilisant un langage sensori-moteur comme le langage des signes dans la vie de tous les jours, s’expose à une réorganisation cérébrale ciblant effectivement la voie dorsale. L’objectif de la première étude est d’explorer ces deux voies visuelles et plus particulièrement, la voie dorsale, chez des individus entendants par l’utilisation de deux stimuli de mouvement dont les caractéristiques physiques sont très similaires, mais qui évoquent un traitement relativement différent dans les régions corticales visuelles. Pour ce faire, un stimulus de forme définie par le mouvement et un stimulus de mouvement global ont été utilisés. Nos résultats indiquent que les voies dorsale et ventrale procèdent au traitement d’une forme définie par le mouvement, tandis que seule la voie dorsale est activée lors d’une tâche de mouvement global dont les caractéristiques psychophysiques sont relativement semblables. Nous avons utilisé, subséquemment, ces mêmes stimulations activant les voies dorsales et ventrales afin de vérifier quels pourraient être les différences fonctionnelles dans les régions visuelles et auditives chez des individus sourds profonds. Plusieurs études présentent la réorganisation corticale dans les régions visuelles et auditives en réponse à l’absence d’une modalité sensorielle. Cependant, l’implication spécifique des voies visuelles dorsale et ventrale demeure peu étudiée à ce jour, malgré plusieurs résultats proposant une implication plus importante de la voie dorsale dans la réorganisation visuelle chez les sourds. Suite à l’utilisation de l’imagerie cérébrale fonctionnelle pour investiguer ces questions, nos résultats ont été à l’encontre de cette hypothèse suggérant une réorganisation ciblant particulièrement la voie dorsale. Nos résultats indiquent plutôt une réorganisation non-spécifique au type de stimulation utilisé. En effet, le gyrus temporal supérieur est activé chez les sourds suite à la présentation de toutes nos stimulations visuelles, peu importe leur degré de complexité. Le groupe de participants sourds montre aussi une activation du cortex associatif postérieur, possiblement recruté pour traiter l’information visuelle en raison de l’absence de compétition en provenance des régions temporales auditives. Ces résultats ajoutent aux données déjà recueillies sur les modifications fonctionnelles qui peuvent survenir dans tout le cerveau des personnes sourdes, cependant les corrélats anatomiques de la surdité demeurent méconnus chez cette population. Une troisième étude se propose donc d’examiner les modifications structurales pouvant survenir dans le cerveau des personnes sourdes profondes congénitales ou prélinguales. Nos résultats montrent que plusieurs régions cérébrales semblent être différentes entre le groupe de participants sourds et celui des entendants. Nos analyses ont montré des augmentations de volume, allant jusqu’à 20%, dans les lobes frontaux, incluant l’aire de Broca et d’autres régions adjacentes impliqués dans le contrôle moteur et la production du langage. Les lobes temporaux semblent aussi présenter des différences morphométriques même si ces dernières ne sont pas significatives. Enfin, des différences de volume sont également recensées dans les parties du corps calleux contenant les axones permettant la communication entre les régions temporales et occipitales des deux hémisphères.
Due to the use of a mode of communication completely different from hearing people, Due to [the use of] a communication mode completely different from hearing people, the sign language and the absence of afferences from the auditory system, it is likely that significant functional and structural changes take place in the brains of profoundly deaf individuals. Previous studies suggest this reorganization may have greater impact on cortical structures located along the dorsal visual pathway than within the regions located inside the ventral pathway. The hypothesis, widely accepted by the scientific community, proposed by Ungerleider and Mishkin (1982) for the presence of two visual pathways in the occipital regions is also fairly contested. According to this hypothesis, one stream projecting from the striate cortex to the posterior parietal regions is involved in spatial vision and a second stream projecting to regions of the inferior temporal cortex underlying form recognition. Goodale and Milner (1992) subsequently proposed that the dorsal pathway, in addition to its involvement in the processing of visuospatial information, takes part in the necessary sensorymotor adjustments to guide actions. In this context, it is plausible to consider that a group of people using sensorimotor language (e.g., sign language) in their everyday life, the cerebral reorganization is more suited to target the dorsal pathway. The first objective of the study is to explore both visual pathways, especially the dorsal pathway, in hearing subjects by the use of two similar motion stimuli that evoke different types of processing. This was done with a form-from-motion stimuli and a global motion stimuli. Our results indicate that both dorsal and ventral pathways process forms defined by motion, while only the dorsal pathway is activated during a task of global motion whose psychophysical characteristics are relatively similar. Subsequently, we used these stimuli to activate the dorsal and ventral stream to investigate functional differences in the visual and auditory brain regions in profoundly deaf individuals. Several studies show cortical reorganization in the visual and auditory areas in response to the absence of a sensory modality. However, few studies have explored the specific involvement of dorsal and ventral visual streams, despite several results suggesting greater involvement of the dorsal pathway in visual reorganization with the deaf population. Following the use of functional brain imaging to investigate these issues, our results differed from the hypothesis suggesting a reorganization specifically targeting the dorsal pathway. Rather, our results indicate a non-specific reorganization to the different types of stimulations used. Indeed, the superior temporal gyrus was activated with the deaf following the presentation of our visual stimuli, regardless of their complexity. The group of deaf participants also showed activation of the posterior association cortex, possibly recruited to process visual information in the absence of competition from the temporal auditory regions. These results add to data already collected on the functional changes that may occur throughout the brains of deaf people, however, the anatomical correlates of deafness remains unknown in this population. A third study aimed to explore the structural changes occurring in the brains of prelingual and congenital profoundly deaf. Our results show that several brain regions appear to be different between the groups of participants composed of the deaf and hearing. Our analysis showed volume increases of up to 20% in the frontal lobe, including Broca's area and adjacent regions involved in motor control and language production. The temporal lobes also presented some morphometric differences even if they are not significant. Though not significant, the temporal lobes also presented some morphometric differences. Finally, differences in volume were also found in parts of the corpus callosum considered to carry fibers connecting the temporal and occipital lobes of both hemispheres.

Abstract:
Exploring the environment without the auditory modality elicits wholesale reorganizations at both the behavioral and the neural levels throughout life. This chapter reviews changes in brain organization and behavior arising from early deafness. It depicts a multifaceted framework in both domains: the performance of deaf persons has been shown to be comparable to, better than, as well as worse than that of hearing participants. They also show brain modifications ascribable both to intramodal (within the visual system) and cross-modal plasticity (the recruitment of the deprived auditory cortex by intact sensory modalities). The authors discuss the implications of these results for sensory rehabilitation and highlight the benefits of multisensory systematic training programs to boost recovery.

Abstract:
The brain exhibits an impressive degree of plasticity, even as it ages. Plasticity is really an intrinsic feature of the nervous system, not an exceptional or occasional state. Neuroplasticity comprises a family of different types of plasticity. Of these, synaptic plasticity is perhaps the best-understood variety, and it plays an important role in cortical map reorganization and memory consolidation. Cortical map plasticity is of direct relevance to any discussion of modularity. There are two types of cortical map plasticity: intramodal (within a modality) and crossmodal. Crossmodal plasticity is likely to arise from the underlying supramodal (or “metamodal”) organization of the brain.

Abstract:
Chapter 7 begins to puts REC positive story into action. It opens by questioning the value of appealing to a priori intuitions in trying to understand the character of perceiving. Focusing on explanatory concerns, it revisits Predictive Processing or PPC proposals about perceiving and defuses arguments that the explanatory punch of PPC requires characterizing perceptual processes and products in representational terms. Instead the chapter shows how REC can successfully appropriate the main apparatus of PPC to explain perception. It demonstrates that mental representations are not needed to explain how intramodal and intermodal forms of perceiving integrate. The chapter concludes by showing how contentless forms of perceiving can connect with contentful attitudes, enabling us to make sense of a range of perceptual phenomena – including our capacity to attune to optical effects and the ways in which we respond to visual illusions.
