SUMMARY:PhD seminar - Fabien Naneix
DESCRIPTION:Venue: Centre Broca \n\nFabien Naneix\nLecturer in Neuroscience\nSMMSN Senior Personal Tutor\nThe Rowett Institute\, University of Aberdeen\, UK \nFabien Naneix was a PhD student and a post-doctoral researcher at INCIA (Coutureau-wolff’s team) in 2012-2017 \nSeminar hosted by Hadrien Plat (PhD student\, INCIA) \nTitle\n“Feed your Teen Spirit”: Differential impact of unbalanced diets during adolescence on action control processes” \nAbstract\nAppropriate control of feeding and food choice is essential for survival and for a healthy life. However\, the increased availability of energy-rich unbalanced diets in modern societies drives unhealthy dietary habits and increases obesity and associated disorders\, such as cardiovascular diseases or type 2 diabetes. As this incidence is now increasingly affecting children and adolescents\, it appears crucial to understand how such unhealthy diets may impact cognitive and brain development and lead to long-term and long-lasting adaptive control of food choices. \nIn this talk\, I will present new unpublished data from different projects aiming at exploring the long-term cognitive and behavioural impact of the exposure to different diets\, all unbalanced in either carbohydrate\, fat or protein\, specifically during adolescence. \nTo investigate the impact of different adolescent diets on action control\, we used specific behavioural approaches based on associative learning (Pavlovian and instrumental conditioning) in a mouse model. Our initial results demonstrate a complex sex- and nutrient-dependent impact of adolescent unbalanced diet on the ability to correctly control food-seeking behaviour according to changes in the value of the food (outcome devaluation)\, changes in action-outcome relationships (reversal learning and contingency degradation) or in response to food-related environmental stimuli (Pavlovian-instrumental transfer). These results may lead to a better understanding of the effect of modern lifestyles on feeding behaviour and metabolic/mental health. \nKey publications\nRougeux et al.
