Bonjour \u00e0 tous et \u00e0 toutes,<\/p>\n

Vous \u00eates cordialement invit\u00e9s au prochain s\u00e9minaire NEURO-Connect, qui aura lieu le 15 avril \u00e0 12h15 au Campus Biotech.<\/p>\n

Les s\u00e9minaires NEURO-Connect visent \u00e0 pr\u00e9senter les diff\u00e9rents domaines de la communaut\u00e9 neuroscientifique du Campus Biotech, allant de la cognition et des \u00e9motions \u00e0 la neurobiologie et \u00e0 la neuroing\u00e9nierie, avec le soutien de toutes les institutions actives sur le site, y compris l’UNIGE (NEUFO, CISA, FPSE), le PRN Evolving Language, l’EPFL (Neuro-X), les HUG, le CIBM et le Wyss Center, et avec le soutien de la Fondation Campus Biotech Gen\u00e8ve.<\/p>\n

La prochaine session sera organis\u00e9e par la CISA. John O’Doherty (California Institute of Technology), qui pr\u00e9sentera un expos\u00e9 intitul\u00e9 \u00ab The brain as a mixture of experts : the neurocomputational basis of multiple parallel systems for learning and control \u00bb (Le cerveau comme un m\u00e9lange d’experts : la base neuro-informatique de multiples syst\u00e8mes parall\u00e8les pour l’apprentissage et le contr\u00f4le). Voir le r\u00e9sum\u00e9 et les autres d\u00e9tails ci-dessous.<\/p>\n

Des rencontres priv\u00e9es avec le professeur O’Doherty peuvent \u00eatre organis\u00e9es, et les chercheurs en d\u00e9but de carri\u00e8re (ECR, par exemple doctorants et postdoctorants) sont encourag\u00e9s \u00e0 se joindre \u00e0 l’orateur invit\u00e9 pour un lunch de r\u00e9seautage offert par le FCBG (10 places, premier arriv\u00e9, premier servi). Pour indiquer votre souhait de rencontrer individuellement le professeur O’Doherty, ou pour vous inscrire au lunch ECR apr\u00e8s la conf\u00e9rence, veuillez remplir le questionnaire suivant jusqu’au mercredi 15 avril : Inscription au lunch<\/a>. Ce d\u00e9lai est n\u00e9cessaire pour pouvoir organiser correctement l’horaire et commander \u00e0 temps le nombre correct de repas. Nous vous remercions de votre coop\u00e9ration.<\/p>\n

Les doctorants peuvent recevoir des cr\u00e9dits pour leur participation, n’oubliez pas de faire signer votre feuille de pr\u00e9sence.<\/p>\n

John O’Doherty (Institut de technologie de Californie)<\/p>\n

Le cerveau, un m\u00e9lange d’experts : la base neuro-informatique de multiples syst\u00e8mes parall\u00e8les pour l’apprentissage et le contr\u00f4le<\/p>\n

Il a longtemps \u00e9t\u00e9 sugg\u00e9r\u00e9 que le comportement humain pouvait \u00eatre compris comme refl\u00e9tant les contributions de multiples syst\u00e8mes qui coop\u00e8rent ou rivalisent pour le contr\u00f4le du comportement. Nous sugg\u00e9rons ici que le cerveau peut \u00eatre consid\u00e9r\u00e9 comme un \u00ab m\u00e9lange d’experts \u00bb dans lequel de multiples syst\u00e8mes experts diff\u00e9rents proposent des strat\u00e9gies d’action. J’examinerai ici comment le cerveau d\u00e9termine quel syst\u00e8me doit contr\u00f4ler le comportement \u00e0 un moment donn\u00e9. Je soutiendrai que cela se fait en gardant une trace de la fiabilit\u00e9 des pr\u00e9dictions de chaque syst\u00e8me et en attribuant le contr\u00f4le du comportement d’une mani\u00e8re qui est proportionnelle \u00e0 la fiabilit\u00e9 relative de ces pr\u00e9dictions. Je pr\u00e9senterai des preuves comportementales de l’existence d’un m\u00e9canisme de contr\u00f4le bas\u00e9 sur la fiabilit\u00e9 fonctionnant sur plusieurs experts chez l’homme. Il s’agit notamment de strat\u00e9gies d’apprentissage par renforcement avec ou sans mod\u00e8le qui apprennent \u00e0 s\u00e9lectionner des actions sur la base de l’exp\u00e9rience directe, d’experts qui apprennent \u00e0 s\u00e9lectionner des actions en observant le comportement d’autres agents, ainsi que d’un syst\u00e8me qui entreprend des actions par r\u00e9flexe en se basant uniquement sur des affordances visuelles. Je pr\u00e9senterai ensuite des donn\u00e9es de neuro-imagerie et de neurostimulation qui sugg\u00e8rent une contribution sp\u00e9cifique du cortex pr\u00e9frontal ventrolat\u00e9ral dans ce processus d’arbitrage bas\u00e9 sur la fiabilit\u00e9. Les r\u00e9sultats de l’\u00e9tude de diff\u00e9rents syst\u00e8mes experts dans les domaines de l’exp\u00e9rience et de l’apprentissage social laissent entrevoir la possibilit\u00e9 que ce m\u00e9canisme de contr\u00f4le bas\u00e9 sur la fiabilit\u00e9 soit g\u00e9n\u00e9ral au domaine, exer\u00e7ant un contr\u00f4le sur de nombreux syst\u00e8mes experts diff\u00e9rents simultan\u00e9ment afin de produire un comportement sophistiqu\u00e9.<\/p>\n
