Transcranial Magnetic Stimulation Trains at 1 Hz Frequency of the Right Posterior Parietal Cortex Facilitate Recognition Memory
2021
Neuroimaging, neuropsychological, and brain stimulation studies have led to contrasting findings regarding the potential roles of the lateral parietal lobe in episodic memory. Studies using brain stimulation methods reported in the literature do not offer unequivocal findings on the interactions with stimulation location (left vs. right hemisphere) or timing of the stimulation (encoding vs. retrieval). To address these issues, active and sham 1 Hz repetitive transcranial magnetic stimulation (rTMS) trains of 600 stimuli were applied over the right or left posterior parietal cortex (PPC) before the encoding or before the retrieval phase of a recognition memory task of unknown faces in a grou…
Haptic Perception in Extreme Obesity: qEEG Study Focused on Predictive Coding and Body Schema
2020
Haptic perception (HP) is a perceptual modality requiring manual exploration to elaborate the physical characteristics of external stimuli through multisensory integrative cortical pathways. Cortical areas exploit processes of predictive coding that collect sensorial inputs to build and update internal perceptual models. Modifications to the internal representation of the body have been associated with eating disorders. In the light of this, obese subjects were selected as a valid experimental model to explore predictive coding in haptic perception. To this purpose, we performed electroencephalographic (EEG) continuous recordings during a haptic task in normally weighted versus obese subjec…
La aplicación de los tributos en los casos de delito contra la hacienda pública
2021
The paper analyses the multiple tax procedures to be developed by the different bodies of the Spanish Tax Authorities (tax management procedures, tax inspection procedures, tax collection and tax penalty procedures) in the case of appreciation of an alleged crime against the Public Treasury. To attain this goal, a study of the new Tax crime configuration after 2012´ criminal reform is carried out, as well as a study of Act 34/2015.
I Symposium of Elite Performance in Combat Sports
2017
This report presents a summary of the I Symposium of Elite Performance in Combat Sports held in Madrid, May 27, 2017. The symposium, organized by the Faculty of Sport Sciences-INEF of the Polytechnic University of Madrid, aimed to bring science closer to practice. A panel of highly successful athletes involved in karate, fencing, and taekwondo shared their experiences. The speakers presented crucial topics for an optimal preparation and high level performance such as strength training, sport psychology, brain maturation, sports nutrition, competition planning, sport injuries, and perceptual-decision making training.
Individualized Template MRI Is a Valid and Reliable Alternative to Individual MRI for Spatial Tracking in Navigated TMS Studies in Healthy Subjects
2020
Objectives: Navigated transcranial magnetic stimulation (nTMS) provides significant benefits over classic TMS. Yet, the acquisition of individual structural magnetic resonance images (MRIindividual) is a time-consuming, expensive, and not feasible prerequisite in all subjects for spatial tracking and anatomical guidance in nTMS studies. We hypothesize that spatial transformation can be used to adjust MRI templates to individual head shapes (MRIwarped) and that TMS parameters do not differ between nTMS using MRIindividual or MRIwarped.Materials and Methods: Twenty identical TMS sessions, each including four different navigation conditions, were conducted in 10 healthy subjects (one female, 2…
A time estimation task as a possible measure of emotions: difference depending on the nature of the stimulus used
2015
Objective: Time perception is fundamental for human experience. A topic which has attracted the attention of researchers for long time is how the stimulus sensory modality (e.g., images vs. sounds) affects time judgments. However, so far, no study has directly compared the effect of two sensory modalities using emotional stimuli on time judgments. Methods: In the present two studies, healthy participants were asked to estimate the duration of a pure sound preceded by the presentation of odors vs. emotional videos as priming stimuli (implicit emotion-eliciting task). During the task, skin conductance (SC) was measured as an index of arousal. Results: Olfactory stimuli resulted in an increase…
Disentangling the Amyloid Pathways: A Mechanistic Approach to Etiology
2020
Amyloids are fibrillar protein aggregates associated with diseases such as Alzheimer’s disease (AD), Parkinson’s disease (PD), type II diabetes and Creutzfeldt–Jakob disease. The process of amyloid polymerization involves three pathological protein transformations; from natively folded conformation to the cross-β conformation, from biophysically soluble to insoluble, and from biologically functional to non-functional. While amyloids share a similar cross-β conformation, the biophysical transformation can either take place spontaneously via a homogeneous nucleation mechanism (HON) or catalytically on an exogenous surface via a heterogeneous nucleation mechanism (HEN). Here, we postulate that…
ICT demand behaviour: An international comparison
2009
This study aims to provide some empirical explanations for the gaps in ICT diffusion between industrialized countries, especially European countries vis-à-vis the United States. The panel data cover eleven OECD countries: Austria, Denmark, Finland, France, Germany, Italy, Japan, the Netherlands, Spain, the United Kingdom and the United States. These annual macroeconomic data span the 1981-2005 period.The analysis provides some original results: (i) the impact on ICT diffusion of the level of education and market rigidities has changed over time. The correlation of ICT diffusion, positive with the level of education and negative with market rigidities, increased over time (in absolute terms)…
L'éthique appliquée à la communication professionnelle
2018
Ce numéro propose une exploration des enjeux éthiques tels qu'ils sont présents aujourd'hui dans différents domaines professionnels du secteur de la communication. Dans l'opinion publique actuelle ces deux termes (« communication », comme métier et activité professionnelle, et « éthique ») semblent parfois opposés : nous rappelions déjà dans le numéro 5 quelques données concernant la méfiance que la communication professionnelle inspire, à l'époque des spin doctors et, plus récemment, des fake news et des faits alternatifs. En réalité, l'éthique est un enjeu de toujours et de toutes les sphères de la vie humaine. C'est inévitable donc que la communication professionnelle soit traversée de f…
Study engagement and burnout profiles among Finnish higher education students
2017
A person-oriented approach was applied to identify profiles of study engagement and burnout (i.e., exhaustion, cynicism, inadequacy) in higher education in a large and representative sample of 12,394 higher education students at different phases of their studies in universities and polytechnics in Finland. Four profiles were identified: Engaged (44%), engaged-exhausted (30%) inefficacious (19%) and burned-out (7%). The engaged students had the most positive engagement accompanied with the least burnout symptoms compared to other groups. The engaged-exhausted students experienced emotional exhaustion simultaneously with academic engagement. The inefficacious group had heightened experience o…
