The quality of cortical network function recovery depends on localization and degree of axonal demyelination

2016

AbstractMyelin loss is a severe pathological hallmark common to a number of neurodegenerative diseases, including multiple sclerosis (MS). Demyelination in the central nervous system appears in the form of lesions affecting both white and gray matter structures. The functional consequences of demyelination on neuronal network and brain function are not well understood. Current therapeutic strategies for ameliorating the course of such diseases usually focus on promoting remyelination, but the effectiveness of these approaches strongly depends on the timing in relation to the disease state. In this study, we sought to characterize the time course of sensory and behavioral alterations induced…

Expectation or Sensorial Reality? An Empirical Investigation of the Biodynamic Calendar for Wine Drinkers.

2017

International audience; The study's aim was to investigate a central tenet of biodynamic philosophy as applied to wine tasting, namely that wines taste different in systematic ways on days determined by the lunar cycle. Nineteen New Zealand wine professionals tasted blind 12 Pinot noir wines at times determined within the biodynamic calendar for wine drinkers as being favourable (Fruit day) and unfavourable (Root day) for wine tasting. Tasters rated each wine four times, twice on a Fruit day and twice on a Root day, using 20 experimenter-provided descriptors. Wine descriptors spanned a range of varietal-relevant aroma, taste, and mouthfeel characteristics, and were selected with the aim of …

The effect of visual motion stimulus characteristics on vection and visually induced motion sickness

2019

Abstract Several factors contribute to the likelihood of experiencing illusory sensations of self-motion (i.e., vection) in Virtual Reality (VR) applications. VR users can also experience adverse effects such as disorientation, oculomotor issues, or nausea known as visually induced motion sickness (VIMS). The goal of the present study was to systematically investigate three characteristics of visual motion stimuli—speed, density, and axis of rotation—and how they relate to both vection and VIMS. Two experiments were conducted. In Experiment 1, a stereoscopic stimulus containing a star field of white spheres on a black background was presented to 21 participants. The stimulus contained linea…

Foam rolling is thought to improve muscular performance and flexibility as well as to alleviate muscle fatigue and soreness. For this reason, foam rolling has become a popular intervention in all kinds of sport settings used to increase the efficiency of training or competition preparation as well as to speed post-exercise recovery. The objective of this meta-analysis was to compare the effects of foam rolling applied before (pre-rolling as a warm-up activity) and after (post-rolling as a recovery strategy) exercise on sprint, jump, and strength performance as well as on flexibility and muscle pain outcomes and to identify whether self-massage with a foam roller or a roller massager is more…

Sensory exploration of the freshness sensation in plain yoghurts and yoghurt-like products

2013

WOS: 000324008600021 ; http://www.sciencedirect.com/science/article/pii/S0950329313001092; International audience; The term "freshness sensation" is used by consumers for characterizing some plain yoghurts and yoghurt-like products. This study consisted in an investigation of this sensation aiming at determining its underlying sensory attributes. First, two focus groups of consumers were conducted to open up the framework. A set of plain yoghurts and yoghurt-like products, both commercial and experimental, was then subjected to sensory analysis. The samples were sorted by means of a free sorting task, and further scored for the intensity of their freshness sensation and their liking, by 72 …

Salt and Aroma Compound Distributions Influence Flavour Release and Temporal Perception While Eating Hot-Served Flans.

2021

International audience; To counteract the negative effect of salt overconsumption on health, strategies have been developed to reduce the salt content in food products. Among them, two promising strategies based on odour-induced saltiness enhancement and the heterogeneous distribution of flavour compounds were combined and assessed in four-layer cream-based snacks. To investigate the relationship between saltiness enhancement, temporal release and perception of flavour compounds in hot snacks with heterogeneous distribution of salt and aroma compounds, complementary techniques were used: nose space PTR-Tof-MS (Proton Transfer Reaction-Time of Flight–Mass Spectrometry) to assess the release …

‘I just want someone to rub some life into them!’ : the lived experience of impaired sensation in the feet related to multiple sclerosis

2021

Background: Impaired sensation in the feet is a commonly reported symptom experienced by people with multiple sclerosis. Aim: To explore the lived experiences of people living with multiple sclerosis-related impaired sensation in their feet. Method: Five open, unstructured interviews were analysed using a descriptive phenomenological method developed by Amedeo Giorgi. Findings: The essential structure of the research phenomenon consists of six key constituents: sense of heightened awareness of body sensation; sense of changed relationship to the feet; sense of changed participation in daily life; sense of the self with multiple sclerosis; sense of the meaning of interaction with others; and…

Psychological predictors of homophobic bullying among adolescents and young adults: The role of parental psychological control and sensation seeking

2021

AbstractWe aimed to investigate the relationship between homophobic bullying, parental psychological control and sensation seeking among adolescents and young adults and to examine the mediating role of sensation seeking. The participants included 394 adolescents and young adults aged 15 to 20 years attending the 3rd, 4th and 5th years of two public high schools in Italian cities. Participants completed the Homophobic Bullying Scale, the Dependency—oriented and Achievement—oriented Parental Psychological Control, and the Sensation—Seeking Scale. The results showed that parental psychological control predicted bullying toward gay and lesbian people. However, the two dimensions of sensation s…

Evaluation der Sexual Sensation Seeking Scale: Ergebnisse einer repräsentativen deutschen Bevölkerungsumfrage

2021

ZusammenfassungBisherige Studien zu Sexual Sensation Seeking (SSS) und der Sexual Sensation Seeking Scale (SSSS) wurden überwiegend an nach dem Alter sowie dem Geschlecht selektierten Stichproben durchgeführt. In dieser Arbeit wurde die deutsche Version der SSSS anhand einer repräsentativen Umfrage an Männern und Frauen evaluiert, welche die gesamte Altersspanne der erwachsenen deutschen Bevölkerung umfasst. Die Gütekriterien und die Faktorenstruktur der deutschen Version der Sexual Sensation Seeking Scale wurden anhand einer repräsentativen Stichprobe von N=2420 Probanden (54% Frauen, 46% Männer) im Alter von 18–93 Jahren (M=50,44, SD=16,97) untersucht. Die SSSS zeigt gute Werte hinsichtli…

Psychometric properties and validation of the sexual sensation seeking scale in Spanish adolescents: Brief screening method for use in research and c…

2018

Abstract Sexual sensation seeking among adolescents has been mostly associated with unprotected sex and other risky behaviors. This paper presents the Spanish adaptation and validation of the Sexual Sensation Seeking Scale (SSSS). This cross-sectional study included 1350 adolescents (601 male and 749 female), aged between 15 and 18 years ( M  = 16.1, SD  = 0.97). Exploratory Factor Analysis (EFA) yielded two components: Physical Sensations Attraction (PSA), and New Experiences Seeking (NES), which together accounted for 48.98% of the total variance. That structure was later verified through Confirmatory Factor Analysis (CFA). Internal consistency was 0.82 for the total scale, and 0.76 and 0…
