SUMMARY:Exhibition "Critical Thinking\, think again !"
DESCRIPTION:Bordeaux Neurocampus is a partner of the exhibition. Several researchers from our community have participated in the design of “Défi curieux”\, one of the animations. \nSpecific events are also planned during the exhibition. More information on these events will be available soon. \n\nAt Cap Sciences – Bordeaux \nWelcome to the exhibition “Critical thinking\, think again! “Rumours\, fake news\, preconceived ideas… Who can you trust? How do you know if information is reliable?Sharpening our critical thinking skills means becoming aware of what can make us vulnerable: our prejudices\, our habits of thought\, our emotions and sometimes… our unjustified mistrust! It is also about finding support to see things clearly. Sometimes it means admitting that we don’t know… In short\, it’s learning to adjust your level of trust.Enter the experience of this exhibition\, play at verifying information\, explore tricky situations\, unmask preconceived ideas. \nThis travelling exhibition “ESPRIT CRITIQUE\, Détrompez–vous! “is part of the off–site activities of the Palais de la découverte (Paris)\, during its temporary closure for renovation. The exercise of critical thinking has been encouraged by the Palais since its creation in 1937. Cap Sciences in Bordeaux and the Quai des Savoirs in Toulouse are convinced of the relevance of this approach and have joined forces with Universcience to co–produce this exhibition\, which is aimed at everyone aged 10 and over. \nAverage duration of the visit : 1h30All public / from 10 years old \nExhibition in four languages: French/English/Spanish/LSF \nOn social networks\, comment and share on the exhibition with : @capsciences #ExpoEspritCritique #EspritCritique \n\nMore details\nCap Sciences\nHangar 20\, Quai de Bacalan\n33300 Bordeaux\nTél. 05 56 01 07 07 \nhttps://www.cap-sciences.net/au-programme/exposition/esprit-critique.html \n\n\n  \n\n

SUMMARY:Exhibition "Disgusting Food Museum"
DESCRIPTION:Cap Sciences \nWith the partnership of Bordeaux Neurocampus / University of Bordeaux \n\nYuck ! What seems disgusting to some is not necessarily so to others ! Who will have the guts to smell that stinky cheese or taste a fermented shark or a cricket ? Disgusting food Museum presents 85 of the world’s most disgusting foods. The opportunity for adventurous visitors to wander from table to table between turtle soup\, insects or hundred–year–old eggs… Everyone puts their disgust to the test\, a beautiful way to change our preconceived ideas\, to question what seems edible or not and to open up to other food practices. This exhibition illustrates the cultural dimension of food and our propensity to change it. Curious” foods from exotic cultures have always fascinated us. In addition to the pleasure of curiosity and discovery\, everyone will be able to put into perspective one of the six fundamental human emotions\, which is disgust. The visit is completed by a tasting at the bar where visitors can test several products from a selection. An exhibition of the Disgusting Food Museum (Malmö Sweden) and with the kind collaboration of the Alimentarium (Vevey Switzerland). Average length of visit: 1 hour All public / from 6 years old On social media\, comment and share about the exhibition with: @capsciences #DisgustingFoodMuseum \n  \nMore details\nhttps://www.cap-sciences.net \n

SUMMARY:Thesis defense - Côme Camus
DESCRIPTION:\n	\n		\n			 Auditorium of the Centre Broca Nouvelle-Aquitaine\n \nAlso via zoom: https://u-bordeaux-fr.zoom.us/j/84724315509?pwd=WVVDZHQ4dUFJMEF5YXJvZGYyZDUwZz09 \n\nDefense in english \nTitre\nInteraction between synaptic plasticity and structural plasticity \nAbstract\nThe brain is a complex network of interconnected neurons responsible for all our cognitive functions and behaviors. Neurons receive inputs at specialized contact zones named synapses which convert an all or none electrical signal to a chemical one\, through the release of neurotransmitters. This chemical signal is then turned back in a tunable electrical signal by receptors to neurotransmitters. However\, a single neuron receives thousands of inputs coming from several neurons in a spatial- and temporal-dependent manner. The precise mechanism by which neurons receive\, integrate and transmit these synaptic inputs is highly complex and is still not perfectly understood. \nAt excitatory synapses\, AMPA receptors (AMPARs) are responsible for the fast synaptic transmission. With the recent developments in super-resolution microscopy\, the community has changed its vision of synaptic transmission. One breakthrough was the discovery that AMPARs are not randomly distributed at synapses but are organized in nanodomains of ~80 nm of diameter containing ~20 receptors. This content is an important factor since it will determine the intensity of the synaptic response. Due to their mM affinity for glutamate\, AMPARs can only be activated when located in an area of ~150 nm in front of the neurotransmitter release site. Moreover\, AMPAR nanodomains have been shown to be located in front of glutamate release sites and to form trans-synaptic nanocolumns. Thus\, the nanoscale organization of AMPARs regarding release sites seems to be a key parameter for the efficiency of synaptic transmission. \nThe overall aim of my PhD has been to determine the influence of this nanoscale organization on the intimate properties of synaptic transmission both at basal state and during plasticity. \nFirst\, we studied how AMPARs are co-organized with other types of glutamate receptors: NMDARs and mGluRs. We showed as well that this fine organization impacts the profile of activation of receptors and therefore regulate synaptic physiology. This work completed our new vision of the role of nano-organization in the synaptic transmission at the basal state. Then\, I studied how this nano-organization enables neurons to adapt their communication. Indeed\, synapses can modulate their strength through long-term synaptic plasticity. As an example\, Long-Term Depression (LTD) corresponds to a long-lasting weakening of synaptic strength and is thought to be important in some cognitive processes and behavioral flexibility through synapse selective elimination. Following previous discoveries about the impact of AMPAR dynamic nano-organization at synapses on the regulation of the synaptic transmission strength and reliability\, I decided to investigate their role in the weakening of synapses. Through this project\, we demonstrated that AMPAR nanodomain content drops down rapidly and this depletion lasts several minutes to hours. The initial phase seems to be due to an increase of endocytosis events\, but in a second phase\, AMPAR mobility is increased following a reorganization of the post-synaptic density. This change in mobility allows depressed synapses to maintain their capacity to answer to high-frequency inputs. Thus\, we propose that LTD-induced increase in AMPAR mobility allows to conduct a reliable response in synapses under high-frequency stimulation and thus to selectively maintain them while eliminating the inactive ones. To confirm this\, I investigated how evolution of synaptic nano-organization regulates the synaptic elimination\, called synaptic pruning\, by modulating the relationship LTD-pruning. Finally\, we showed that the isolation in time and space of a synapse favors its pruning following specific molecular reshufflings induced by LTD. \nKeywords: synaptic transmission\, AMPA receptors\, PSD-95\, synaptic organization\, synaptic plasticity\, structural plasticity \nPublications\n\nNMDAR-dependent long-term depression is associated with increased short term plasticity through autophagy mediated loss of PSD-95\nBenjamin Compans*\, Come Camus*\, Emmanouela Kallergi \, Silvia Sposini\, Magalie Martineau\, Corey Butler\, Adel Kechkar\, Remco V Klaassen\, Natacha Retailleau\, Terrence J Sejnowski\, August B Smit\, Jean-Baptiste Sibarita\, Thomas M Bartol Jr\, David Perrais \, Vassiliki Nikoletopoulou\, Daniel Choquet\, Eric Hosy.
