Mechanisms involved in the control of feeding behavior in relation to food flavor

2016

Revue; IntroductionIntake is one of the most essential behaviors, since human beings, like any living organism, require adequate nutrients for their survival. Ingestive behavior is controlled to maintain energy balance by peripheral and central mechanisms. When physiological needs are not being met, they will lead to motivation. Thus, being hungry will motivate us to find food, and the motivation will cease when needs are met. Ingestive behavior is thus initially due to a need related to internal signals (Fig. 10.1), in this case, hunger (physiological need) and appetite (urge to eat a food from which we expect pleasure and satisfaction). Sensory (visual, olfactory and, to a lesser extent, …

Twin studies on the association of physical activity with cognitive and cerebral outcomes

2020

Regular physical activity (PA) offers positive effects on the human body. However, the effects of PA on cognition and in the brain are less clear. In this paper, we narratively review the relationship of PA with cognition and dementia, first from general perspective and then through genetically informed studies on the topic. Then we move on to imaging studies on exercise and brain anatomy first by presenting an overall picture of the topic and then discussing brain imaging studies addressing PA and brain structure in twins in more detailed way. Regarding PA and cognition or dementia, genetically informed studies are uncommon, even though the relationship between PA and cognitive ageing has …

Severe Perinatal Hypoxic-Ischemic Brain Injury Induces Long-Term Sensorimotor Deficits, Anxiety-Like Behaviors and Cognitive Impairment in a Sex-, Ag…

2019

Perinatal brain injury (PBI) leads to neurological disabilities throughout life, from motor deficits, cognitive limitations to severe cerebral palsy. Yet, perinatal brain damage has limited therapeutic outcomes. Besides, the immature brain of premature children is at increased risk of hypoxic/ischemic (HI) injury, with males being more susceptible to it and less responsive to protective/therapeutical interventions. Here, we model in male and female C57BL/6 mice, the impact of neonatal HI and the protective effects of neonatal handling (NH), an early life tactile and proprioceptive sensory stimulation. From postnatal day 1 (PND1, modeling pre-term) to PND21 randomized litters received either…

First Chemosensor for Selective Detection and Quantification of L-4-Hydroxyproline in Collagen and Other Bio Samples.

2017

Amino pyridine-based rhodamine conjugate (APR) has been developed as a first chemosensor for selective detection and quantification of L-4-Hydroxyproline (Hyp). The “turn-on” fluorescence property of the chemosensor makes it unique for easy estimation of Hyp in collagen and biological samples. peerReviewed

Dangers of Demosaicing : Confusion From Correlation

2019

Images from colour sensors using Bayer filter arrays require demosaicing before viewing or further analysis. Advanced demosaicing methods use empirical knowledge of inter-channel correlations to reduce interpolation artefacts in the resulting images. These inter-channel correlations are however different for standard RGB cameras and hyperspectral imagers using colour sensors with added narrow-band spectral filtering. We study the effects of conventional demosaicing methods on hyperspectral images with a dataset originally collected without a colour filter array. We find that using advanced methods instead of bilinear interpolation results in an overall increase of 9–14 % in absolute error a…

"Having a drink in a bar": An immersive approach to explore the effects of context on drink choice

2013

UT: 000315557500004; International audience; This paper aims to evaluate the effect of context on food choices. Two studies are presented to test the potential of an immersive approach to help understanding contextual influences on drink choices. To generate contextual effects, two bar-like environments based on the idea of "having a drink in a bar" were created: one with wood furniture and one with blue furniture. In both immersive bars, clips with visual and music stimuli were projected on a wall to change the overall warmth of the ambience. In the first study, five different clips were projected. Participants in the immersive bars had to choose a drink within a large range of drinks for …
