Faut-il imposer un contrôle aux enfants ?

2019

Participation à une table ronde en visioconférence.; Les parents jouent un rôle déterminant dans le développement des habitudes et comportements alimentaires des enfants. L'enfant, notamment le très jeune enfant, n'est pas prescripteur de son alimentation. Il dépend de l'offre proposée (le « QUOI ») par ses parents, des horaires et des contextes de consommation qui lui sont imposés, des valeurs familiales, sociales ou culturelles environnant la prise alimentaire, mais aussi des stratégies éducatives en matière d'alimentation privilégiées par les prescripteurs (le « COMMENT ») (Rigal et al., 2012 ; Monnery-Patris et al., 2019). Ce contrôle parental externe peut avoir des effets délétères sur…

2021

International audience; A functional sense of smell is essential for evaluating and enjoying food, receiving information about conspecifics, and detecting threats via airborne chemical cues. Olfactory dysfunction has been associated with an impaired quality of life, reflected by a higher incidence of undesirable mental states such as depression and social insecurity. Addressing and overcoming related olfactory dysfunction issues require a detailed understanding of peripheral and central processes involved in olfaction. Consequently, there is a growing body of research unravelling molecular and cellular interactions that shape olfactory sensation. Recent studies have demonstrated that in the…

Functional analysis of broadly tuned odorant receptors expressed in the mouse septal organ through patch-clamp recordings in an intact preparation an…

2010

The septal organ (SO) is a small island of olfactory epithelium located at the ventral base of the nasal septum. SO neurons express identified odorant receptors, but its function remains unknown. Using perforated patch clamp recordings, we investigated the response properties of SO neurons in the intact epithelium of mice to a panel of 45 odorants or mixtures. Out of 328 neurons tested, approximately 70% responded to odor stimulation. Among the responsive neurons, 72.5 % responded to multiple odorants. Responding neurons were tested with increasing concentrations of 3 odorants (octanoic acid, (+) camphor, amylacetate) and a mixture (fox urine). Dose-response curves show nanomolar threshold …

Evidence of neonatal memory of odor configuration

2013

The perception of some mixtures of odorants engages configural abilities, i.e. the perception of these mixtures as single odor objects. For instance, data in human adults demonstrated that a mixture of two odorants (AB), one smelling like strawberry and the other like caramel, generates the configural perception of the odor of pineapple (Le Berre et al., 2008; Barkat et al., 2012). Configural processing may be adaptive also for young organisms, to which rapid extraction of chemical information from the maternal environment, highly complex, is a prerequisite to survival. Thus, results in newborn rabbits suggest the perception of a unique odor in the AB mixture (smelling like configural pinea…

Le petit mangeur âgé : quand l'appétit fragilise le statut nutritionnel

2018

National audience; Le vieillissement est associé à de nombreux changements physiologiques, sensoriels, psychologiques et sociologiques susceptibles d'avoir un impact délétère sur la prise alimentaire de la personne âgée. Dans le cadre de RENESSENS, 68 personnes âgées vivant en institution (66 à 100 ans ; 87,4±0.9 d'âge moyen ; 75% de femmes) ont été recrutées et suivies pendant 24 heures de façon à peser tous les aliments et toutes les boissons consommées. Les résultats ont montré que 83% des résidents ne satisfaisaient pas à leurs besoins caloriques et protidiques (43% présentaient un apport inférieur au 2/3 des apports conseillés), essentiellement à cause d'une consommation insuffisante d…
