Functional evidence of multidrug resistance transporters (MDR) in rodent olfactory epithelium.
2012
WOS: 000305340700029; International audience; BACKGROUND: P-glycoprotein (Pgp) and multidrug resistance-associated protein (MRP1) are membrane transporter proteins which function as efflux pumps at cell membranes and are considered to exert a protective function against the entry of xenobiotics. While evidence for Pgp and MRP transporter activity is reported for olfactory tissue, their possible interaction and participation in the olfactory response has not been investigated. PRINCIPAL FINDINGS: Functional activity of putative MDR transporters was assessed by means of the fluorometric calcein acetoxymethyl ester (calcein-AM) accumulation assay on acute rat and mouse olfactory tissue slices.…
Project DyAdd: Non-linguistic Theories of Dyslexia Predict Intelligence
2020
Two themes have puzzled the research on developmental and learning disorders for decades. First, some of the risk and protective factors behind developmental challenges are suggested to be shared and some are suggested to be specific for a given condition. Second, language-based learning difficulties like dyslexia are suggested to result from or correlate with non-linguistic aspects of information processing as well. In the current study, we investigated how adults with developmental dyslexia or ADHD as well as healthy controls cluster across various dimensions designed to tap the prominent non-linguistic theories of dyslexia. Participants were 18–55-year-old adults with dyslexia (n = 36), …
Expert en visages: sommes-nous programmés pour reconnaître les visages ?
2017
International audience; Experts en visages, nous le sommes tous : chacun d’entre nous est capable de reconnaître et de mémoriser des centaines de visages. Mais quel est le processus cognitif à l’œuvre, qui fait que le nourrisson est capable de reconnaître le visage de sa mère ? Selon quels phénomènes, dès le plus jeune âge, le visage prend-il une telle importance ? Sommes-nous programmés génétiquement à reconnaître les visages ou est-ce lié à un apprentissage ? Quelles sont les pathologies qui ont un impact sur la reconnaissance du visage ?À travers ce livre, l’auteur fait une synthèse des recherches sur le visage, qu’il aborde sous les aspects à la fois cognitifs et neuropsychologiques. Il…
The lyon clinical olfactory test: validation and measurement of hyposmia and anosmia in healthy and diseased populations.
2011
; International audience; The LCOT is a self-administered test designed to assess olfactory deficits. Altogether, 525 subjects contributed to the validation. Elderly participants were well represented in this sample. In a validation study (study 1), 407 healthy and 17 anosmic volunteers between 15 and 91 years of age underwent threshold, supraliminal detection, and identification testing. Cutoff values for normosmia and hyposmia were calculated and applied in a second study in a group of patients with smell complaints and in a group of Alzheimer patients with age-matched controls. Incidence of smell deficit was estimated at 5.6% in the healthy population of study 1, and at 16% in the elder…
The odour of human milk: Its chemical variability and detection by newborns
2019
International audience; Human milk odour has for long elicited research interest with regard to its function in breastfeeding initiation. The present review aims to provide an overview of the behavioural effects of human milk odour in the human neonate, considering different types of response measures in a feeding or non-feeding context. Further, an overview of the current knowledge of odorant composition and factors influencing milk odour is provided by summarizing results from analytical studies using olfactometry, and addressing changes in milk odour due to storage, lactational stage, and maternal dietary intake of odorous substances. We finally highlight some issues for future research.
Artisans-chercheurs -- Récit d'une expérience d'apprentissage en lutherie des flûtes populaires et de ses implications dans la recherche archéomusico…
2016
International audience; Cet article présente l’expérience et le vécu d’un apprentissage artisanalinséré au sein d’une recherche doctorale en tant qu’élémentméthodologique et épistémologique. À travers les prismes de l’ethnographieet des sciences cognitives, nous nous attacherons donc à endécrire l’organisation et la faisabilité (dans l’espoir de fournir quelquesclefs afin qu’une telle expérience puisse être renouvelée par d’autresque nous) ainsi que les effets et apports mutuels (dans la productionde l’artisan d’une part, et dans la recherche universitaire d’autre part).
Learning from Implicit Learning Literature: Comment on Shea, Wulf, Whitacre, and Park (2001)
2003
International audience; In their analysis of complex motor skill learning, Shea, Wulf, Whitacre, and Park (2001) have overlooked one of the most robust conclusions of the experimental studies on implicit learning conducted during the last decade--namely that participants usually learn things that are different from those that the experimenter expected them to learn. We show that the available literature on implicit learning strongly suggests that the improved performance in Shea et al.'s Experiments 1 and 2 (and similar earlier experiments, e.g., Wulf & Schmidt, 1997) was due to the exploitation of regularities in the target pattern different from those on which the postexperimental intervi…
Scientific writing for impact factor journals
2013
EASARCICAPLivre dispo. dans :hal-00832739, version 1; Publish or Perish. This old adage illustrates the importance of scientific communication; essential to research, it also represents a strategic sector for each country’s competitiveness. An often-neglected topic, scientific communication is of vital importance, with new information technologies accelerating and profoundly changing how knowledge is disseminated. The necessity of optimally disseminating experts’ findings has also become crucial to researchers, institutes and universities alike, which has prompted the recent advent of Impact Factors for the evaluation and financing of research, the goal being for scientific knowledge to be …
