Mammary pheromone-induced odour learning influences sucking behaviour and milk intake in the newborn rabbit

Articles

Mélanie Jouhanneau et al. (2016)

Articles

Newborn rabbits, Oryctolagus cuniculus, locate their mother's nipples through typical orocephalic movements elicited by odour stimuli, in particular by the mammary pheromone (MP). The MP also promotes neonatal odour learning: after single pairing with the MP, an initially neutral odorant becomes abl...

Configural processing of odor mixture: Does the learning of elements prevent the perception of configuration in the newborn rabbit?

Articles

Sébastien Romagny et al. (2015)

Articles

Although elemental perception of odor mixtures allows us to perceive the component odor qualities, configural perception leads to the emergence of a new odor percept. The 6-odorant Red Cordial (RC) mixture is weak configurally perceived in newborn rabbits, meaning that pups respond to the odorants a...

Neural activation induced by an odour mixture perceived elementally or configurally by the newborn rabbit

Conferences and symposiums

Nanette Y. Schneider et al. (May 21, 2013)

Conferences and symposiums

Perception of odours plays a crucial role in mammals facilitating interindividual communication, food choice and detection of danger, even from early in life (e.g. mother-young communication). However, little is known about the brain processing and perception of odorants in mixtures, which is by far...

The best COVID-19 predictor is recent smell loss: a cross-sectional study

Preprint

Richard Gerkin et al. (Nov 16, 2020)

Preprint

Background: COVID-19 has heterogeneous manifestations, though one of the most common symptoms is a sudden loss of smell (anosmia or hyposmia). We investigated whether olfactory loss is a reliable predictor of COVID-19. Methods: This preregistered, cross-sectional study used a crowdsourced questionna...

Maternal influences on the vocal development of the Japanese quail (Coturnix c. japonica)

Thesis

Lucie Desmedt (Dec 19, 2019)

Thesis

Social influences on vocal development have been particularly studied in songbirds. In these species, young are capable of vocal learning, that is to say, they modify the structure of their vocalization following vocal interactions with the congeners, often parents. Conversely, in non-vocal leaners...

Role and connectivity of adult-born neurons in the olfactory bulb

Thesis

Anne Grelat (Jun 29, 2018)

Thesis

Olfaction is an important sensory modality in rodents. During odor-dependent learning, a positive value is commonly assigned to an odorant, and multiple forms of plasticity are involved when such odor–reward associations are formed. In the olfactory bulb, one of the mechanisms underlying plasticity...

Orosensory detection of dietary lipids in the mouse : mechanisms involved and alterations during obesity

Thesis

Deborah Ancel (Dec 21, 2015)

Thesis

Dietary lipids are detected by the gustatory system in rodents and humans. Two candidate lipid-receptors are found in taste buds: CD36, which is involved in the fat taste as shown by studies conducted in our laboratory, and GPR120. Our results show that GPR120 is not directly involved in the gustato...

Sensory, cognitive and behavioural processes involved in complex odor mixture perception in the newborn rabbit and in humans

Thesis

Sébastien Romagny (Feb 13, 2015)

Thesis

Within each breath, a large diversity of volatiles molecules of the surrounding reaches our olfactory receptors. Despite the chemical complexity of the natural environment, the organisms succeed to represent their world using single odorants or mixtures. The treatment is then based on two processes:...

Division of labour, olfactory learning and perception in the ant camponotus aethiops

Thesis

Margot Perez (Jan 8, 2015)

Thesis

Ants in compex societies where different individuals are specialized in particular tasks. In their natural environnement, the majority of ants species rely on olfactory cues. We aimed at understanding division of labour, olfactory perception and learning in the ant C. aetiops. The species forages pa...

Pre-lactation behavior in mice : characterization of maternal reactive secretions and involvement of the neonatal experience

Thesis

Syrina Al Aïn (Dec 18, 2012)

Thesis

Birth is one of the most delicate periods mammalian infants have to deal with. Newborns have then to adapt physiologically and behaviorally to the aerial environment, and one of their first challenges is to ingest colostrum and milk. It is paradoxical that the survival of pups is conditioned by the...

Perception of odour mixtures : behavioural and psychophysical study in newborn rabbits and human adults

Thesis

Charlotte Sinding (Apr 13, 2012)

Thesis

Through our senses, we can grasp the complexity of the stimuli that arise from our surroundings. Within the animal kingdom, two systems of information processing exist: one elemental and the other configural. Which factors promote each of these types of perception? Do they persist across lifespan? D...
