Transcranial magnetic stimulation (TMS) is a noninvasive means of investigating the function, plasticity, and excitability of the human brain. TMS induces a brief intracranial electrical current, which produces action potentials in excitable cells. Stimulation applied over the motor cortex can be used to measure overall excitability of the corticospinal system, somatotopic representation of muscles, and subsequent plastic changes following injury. The facilitation and inhibition characteristics of the cerebral cortex can also be compared using the modulatory effect of a conditioning stimulus preceding a test stimulus. So called paired-pulse protocols have been used in humans and animals to assess GABA (gamma-amino-butyric acid)-ergic function and may have a future role directing therapeutic interventions. Indeed, repetitive magnetic stimulation, where intracranial currents are induced by repetitive stimulation higher than 1 Hz, has been shown to modulate brain responses to sensory and cognitive stimulation. Here, we summarize information gathered using TMS with patients in coma, vegetative state, and minimally conscious state. Although in the early stages of investigation, there is preliminary evidence that TMS represents a promising tool by which to elucidate the pathophysiological sequelae of impaired consciousness and potentially direct future therapeutic interventions. We will discuss the methodology of work conducted to date, as well as debate the general limitations and pitfalls of TMS studies in patients with altered states of consciousness. [less ▲]

A zone with significant irreversible processes and significant changes in flow and transport properties is expected to be formed after underground excavations. The perturbation of the excavation could lead to a significant increase of the permeability, related to diffuse and/or localized crack proliferation in the material. The main objective of the study is to model these processes at large scale in order to assess their impacts on the performance of radioactive waste geological repositories. This paper concerns more particularly the hydro-mechanical modeling of a long term dilatometer experiment performed in Mont Terri Rock Laboratory in Switzerland. The proposed model defines the permeability as a function of the aperture of the cracks that are generated during the excavation. With this model, the permeability tensor becomes anisotropic. These developments are validated with the results of the experiment. [less ▲]

Experts agree that PE can play a key role in the promotion of a lifelong active lifestyle. In many countries, the PE teacher is seen as the most appropriate staff member to coordinate health education at school. However, in Belgium the PE programme does not expressively mention lifelong active lifestyle as a priority objective (Ministère de la Communauté française, 2000). Nevertheless, PE teachers consider traditionally that they should encourage lifelong sport participation but there is no study verifying whether they actually do. Our purpose was to verify wether Wallonian PE teachers were aware of their role as physical activity promoters by identifying the actions that they use in their schools. [less ▲]

This study examined cognitive representations of routine action, through the assessment of level of agency, in individuals with sub-clinical checking. The level of agency stems from Action Identification Theory [Vallacher, R. R., Wegner, D. M. (1989). Levels of personal agency: Individual variation in action identification. Journal of Personality and Social Psychology 57, 660-671], which states that how actions are usually identified (based on instrumental aspects or purpose) reflects the predominant accessibility of internal representation (movements executed vs. goal pursued). Furthermore, this framework proposed that altered action regulation is related to low-level of agency (i.e., action identification at an instrumental level). In the current study, the main result indicated that checking symptoms were related to a low-level of agency, that is, individuals with sub-clinical checking identified habitual actions on the basis of instrumental aspects. This seems to indicate that checkers may act with a lack of goal representations. The results are discussed in terms of the role of low-level of agency in checking phenomena and related cognitive dysfunction. [less ▲]

The concept of the ‘active school’ emerged a decade ago as the role with increasing recognition of the role of schools in the promotion of physical activity. The purpose of this paper is to present the findings of a study which, drawing on Cale’s ‘Active School’ model, aimed to compare the nature and extent of physical activity promotion in secondary schools in three European regions. In so doing, it aimed to establish whether there were cultural differences in the strategies and approaches adopted by schools. [less ▲]

Our study focused on an analysis of secondary schools which were renowned for placing a real emphasis on physical education, sport and/or active lifestyles. The originality of this research lies in the fact that the study represents a comparison of schools from three different cultures in Europe. Our purpose was to determine whether the students were aware of the role their secondary school played in promoting an active lifestyle and influencing their physical activity levels. The findings should provide useful feedback to practitioners in terms of both their current and future practice. [less ▲]

Anxiety and sexual arousal have often been considered as incompatible. Since the end of the 20th Century, however, researches have impaired theories centred on the inhibitory effect of the stress and on peripheral explanations; they rather focus attention on the complexity of the relations between the two states and on cognitive mechanisms. <br />Now sexual arousal tends to be regarded as a complex response that requires the convergent interpretation of internal and external stimuli. Anxiety may have different effects on this process, sometimes neutral, sometimes facilitating and sometimes inhibitory. <br />On the one hand, anxiety can trigger a vegetative emotional reaction that may be associated to a concomitant erotic stimulation. Thus, anxiety facilitates the sexual response: this can be called a priming effect. This effect is regularly observed in labs, mainly among women. It likely also works in certain compulsive sexual behaviours or, more commonly, in those numerous persons that report being sexually aroused when stressed. <br />On the other hand, anxiety can cause a massive irruption of non erotic cues in working memory. Therefore, cognitive function available for treating erotic stimuli is diminished and sexual response is impaired. This is an effect of cognitive interference. A trait called erotophobia could be regarded as a vulnerability factor to cognitive interference. Erotophobic subjects are characterized by a trend to focus upon danger-related information when they are in a sexual situation and by a higher risk of sexual dysfunction. [less ▲]
