SUMMARY:Monthly conference (PhD seminar) - Vladan Lucic
DESCRIPTION:\n	\n		\n			Centre Broca Nouvelle-Aquitaine \n\n\n		\n	\n\n	\n		\n			Title : Architecture of trans-synaptic assemblies at the single nanometer scale. \nNeurotransmitter release is mediated by a complex and highly regulated molecular machinery. We imaged isolated synapses by cryo-electron tomography (cryo-ET)\, a method that utilizes faithful sample preservation and direct 3D imaging of fully hydrated\, unlabeled biological material at 2-4 nanometer resolution. The computational procedures for template-free detection and classification in cryo-tomograms that we developed allowed us to quantitatively analyze the spatial organization and inter-relation of synaptic complexes. We showed that tripartite trans-synaptic assemblies (subcolumns) link synaptic vesicles to postsynaptic ionotropic glutamate receptors\, and established that a particular displacement between the interacting complexes characterizes subcolumns. Furthermore\, we obtained de novo average structures of ionotropic glutamate receptors in their physiological composition\, embedded in plasma membrane. In a separate set experiments\, we found that Munc13 and SNAP25\, proteins known to be essential for synaptic vesicle priming for release and fusion\, control the location of synaptic vesicles at a single nanometer precision by tethering them to the plasma membrane\, resulting in two stable primed vesicle states. Furthermore\, these two proteins\, together with protein kinase C\, control the transition between the two primed states by coordinated reorganization of both tethers and molecular bridges (connectors) that interlink vesicles. Together\, our data supports the hypothesis that synaptic transmission is carried by precisely aligned trans-synaptic units that are organized in large molecular assemblies of variable architecture. \nPublications\nMartinez-Sanchez wt al.\, 2021.

SUMMARY:Le procès de l'intelligence artificielle
DESCRIPTION:Lieu : Amphitéâtre de la Maison de l’Economie (bât H)\n16\, avenue Léon Duguit 33600 Pessac\n \n\nSeriez-vous prêts à être gouvernés par une intelligence artificielle ? A décision exceptionnelle\, procès exceptionnel ! \n\nBordeaux Macropole\, 2050. Le scandale éclate lorsque l’on découvre que ce qui nous gouverne depuis trois ans n’est pas un humain mais une intelligence artificielle ! Et pourtant\, tout allait merveilleusement bien depuis son élection. Plus de pollution ni de bouchon\, du travail pour toutes et tous et une douceur de vivre unanimement partagée. Que doit-on faire ? Souhaite-on être gouverné par une intelligence artificielle ?\nPrétexte à un exercice de médiation scientifique\, ce procès fictif est l’occasion de faire témoigner à la barre une quinzaine chercheurs issus de nombreux champs disciplinaires (des neurosciences à l’économie\, en passant par le doit\, la philosophie\, les sciences computationelles\, etc). A l’issue des débats\, la décision sera prise par le vote du public. \nInformations pratiques\n\n\nRéservation obligatoire\nContact et réservation\nhttps://forms.gle/4WiAe6HZ9WCUKo9C6 \n\n\nPublics concernés\n15 – 18 ans\, 18 – 25 ans\, 25 ans et + \n\n\nCapacité\n200 personnes max.\n\n\n
