Thinkbase: Mapping the World's Brain If Freebase is an "open shared database of the world's knowledge," then Thinkbase (found via information aesthetics) is a mind map of the world's knowledge. The interesting and incredibly addictive Freebase visualization and search tool is the brainchild of master's degree student Christian Hirsch at the University of Auckland. Thinkbase is one of the cool proof of concept applications built on top of Freebase that we mentioned last week. As we've mentioned here on RWW, Freebase is best suited for complex inferencing queries -- the type that expose relationships between various entities to figure out an answer. Things like, "What's the name of the actor who was in both "The Lord of the Rings" and "From Hell?" Thinkbase doesn't necessarily answer those questions -- at least not directly, but it does allow people to visually explore the relationships that Freebase can expose.

Neural Correlates of Lyrical Improvisation: An fMRI Study of Freestyle Rap : Scientific Reports In this study, we used fMRI to investigate the neural correlates of spontaneous lyrical improvisation by comparing spontaneous freestyle rap to conventional rehearsed performance. Our results reveal characteristic patterns of activity associated with this novel form of lyrical improvisation, and may also provide more general insights into the creative process itself. It has been suggested that the creative behaviors could occur in two stages: an improvisatory phase characterized by generation of novel material and a phase in which this material is re-evaluated and revised1. A second salient feature of improvisation revealed by the GLM contrasts was a marked lateralization of task-related changes in the BOLD signal. Activation of left hemisphere language areas (in inferior frontal and posterior middle and superior temporal gyri) was predicted and is perhaps unsurprising given the nature of the genre.

Birth of the global mind The best symbiosis of man and computer is where a program learns from humans but notices things they would not Global consciousness. We’ve heard that before. In the 1960s we were all going to be mystically connected; or it would come as a super-intelligent machine – Terminator’s Skynet – that is inimical to humanity. And yet, what if the reality is more mundane? Computer scientist Danny Hillis once remarked, “Global consciousness is that thing responsible for deciding that pots containing decaffeinated coffee should be orange.” What is different today, though, is the speed with which knowledge propagates. One might say that this is the same underlying mechanism of human knowledge capture and retransmission that has always driven the advance of civilisation. The web is a perfect example of what engineer and early computer scientist Vannevar Bush called “intelligence augmentation” by computers, in his 1945 article “As We May Think” in The Atlantic.

Le cerveau préfère le sport au tabac ! Actualités Par Yan Di Meglio rédigé le 28 novembre 2012, mis à jour le 28 novembre 2012 Le cerveau préfère le sport au tabac ! Le cerveau préfère le sport au tabac ! Pour protéger le cerveau d'un vieillissement prématuré, les exercices de stimulation et les tests de mémoire sont régulièrement conseillés. Selon une étude écossaise publiée dans la revue Neurology, il semblerait cependant qu'il y ait plus efficace encore : le sport ! Ces scientifiques ont observé les pratiques sportives régulières de 700 personnes de plus de 70 ans. Les escaliers plutôt que l'escalator C'est le système cardiovasculaire, en meilleur état chez les sportifs, qui explique la résistance du cerveau au vieillissement, car il est mieux oxygéné. Des tests pratiqués sur près de 9 000 personnes de plus de 50 ans ont révélé des carences dans les facultés cognitives de certains d'entre eux. Et en finir avec le tabac Nous savions déjà que le tabac altérait l'oxygénation du cerveau. En savoir plus Mots clés Réagir à cet article

Superintelligence A superintelligence, hyperintelligence, or superhuman intelligence is a hypothetical agent that possesses intelligence far surpassing that of the brightest and most gifted human minds. ‘’Superintelligence’’ may also refer to the form or degree of intelligence possessed by such an agent. Technological forecasters and researchers disagree about when human intelligence is likely to be surpassed. Some argue that advances in artificial intelligence (AI) will probably result in general reasoning systems that lack human cognitive limitations. Experts in AI and biotechnology do not expect any of these technologies to produce a superintelligence in the very near future. Definition[edit] Summarizing the views of intelligence researchers, Linda Gottfredson writes: Intelligence is a very general mental capability that, among other things, involves the ability to reason, plan, solve problems, think abstractly, comprehend complex ideas, learn quickly, and learn from experience. Feasibility[edit]

L'hyperstimulation du deuxième cerveau «La physiopathologie du syndrome de l'intestin irritable est encore méconnue mais, en l'abordant par ses symptômes, de nombreux phénomènes se produisant notamment au niveau de l'intestin ont pu être identifiés», souligne Michel Neunlist, directeur de l'unité Inserm de neuro-gastro-entérologie de l'Institut des maladies de l'appareil digestif (Imad) à Nantes. En étudiant la douleur, les chercheurs ont pu constater que les patients SII présentent souvent une sensibilité accrue au stimulus douloureux, traduit au niveau du système nerveux central (le cerveau). Les troubles digestifs pourraient eux être liés à un trouble de la motricité de l'intestin liée au système nerveux entérique (SNE), parfois considéré comme un deuxième cerveau. L'intestin est en effet l'une des zones les plus innervées de l'organisme et ce réseau nerveux est responsable, de façon autonome, de certaines fonctions digestives comme le mouvement péristaltique qui fait progresser les aliments dans l'intestin.

Noogenesis Noogenesis (Ancient Greek: νοῦς=mind + γένεσις=becoming) is the emergence of intelligent forms of life. The term was first used by Pierre Teilhard de Chardin in regard to the evolution of humans. It also used in astrobiology in regard to the emergence of forms of life capable of technology and so interstellar communication and travel. Teilhard[edit] Noogenesis began with reflective thought; or with the first human beings. Teilhard imagines that noogenesis will eventually reach a critical point of consciousness, brought about by a maximum tension of human socialization. Astrobiology[edit] In astrobiology noogenesis concerns the origin of intelligent life and more specifically technological civilizations capable of communicating with humans and or traveling to Earth.[1] The lack of evidence for the existence of such extraterrestrial life creates the Fermi paradox.

COMA: Face au traumatisme, le cerveau se réorganise COMA: Face au traumatisme, le cerveau se réorganise Actualité publiée le 29-11-2012 Inserm et PNAS Une réorganisation des réseaux cérébraux, tel un mécanisme de résistance du cerveau au traumatisme, c’est ce que constatent ces chercheurs de l'Inserm qui ont analysé les réseaux cérébraux de patients dans le coma, un état où la personne est considérée comme "inconsciente". L’Inserm rappelle que le coma est un état où l'on observe une abolition de la conscience de soi et du monde extérieur et qu’il existe deux phases de coma, la phase dite "aigüe" puis la phase dite "chronique". Leurs résultats montrent que, · la connectivité cérébrale globale est conservée chez les patients dans le coma en comparaison avec les volontaires sains. · Mais la connectivité au niveau local, est réorganisée : La connectivité dans certaines régions cérébrales fortement connectées chez les patients sains est plus faible chez les patients dans le coma.

Curation: How the Global Brain Evolves | Underwire By Eliot Van Buskirk, “Those who can, do. Those who can’t, review. That quote is zinging around the internet this week. [partner id="evolverfm"] The sentiment expressed above is funny, in a mocking sort of way. Unfortunately, it makes as little sense as the quote upon which it is based: “Those who can do. This is what people have always done: pass along things we find worthwhile. Plenty of person-to-person sharing goes on these days, obviously. There’s too much stuff. An academic librarian recently asked me to comment on what it means when people “curate” content for an upcoming article in a search-oriented publication. When we curate, we are enhancing a connection in the global neural network we are inadvertently creating. “Content curation is the natural evolution of our globally networked consciousness. is about music apps and digital music.

Des chercheurs ont rajeuni le cerveau… d’abeilles Avec des sociétés humaines où l'espérance de vie ne cesse d'augmenter, la prévalence des maladies que l'on regroupe sous l'expression de "démence sénile" (essentiellement la maladie d'Alzheimer) est elle aussi à la hausse. D'où l'intérêt croissant de la science pour des modèles animaux permettant aux chercheurs de travailler sur les différents aspects de la sénescence. Et parmi ces modèles, on trouve l'abeille ouvrière dont la vie courte tient en l'espace de cinq à six semaines durant lesquelles elle occupe différents "postes" dans la société : elle commence par travailler à l'intérieur de la ruche, comme nettoyeuse, nourrice pour les larves, magasinière, ventileuse, cirière. Certaines s'aventurent ensuite à l'extérieur, d'abord pour garder l'entrée de la ruche puis pour butiner. On pourrait se dire que c'est le simple effet de l'âge. Il reste à découvrir comment fonctionnent les processus biochimiques qui restaurent les capacités cognitives perdues.

World Brain World Brain is a collection of essays and addresses by the English science fiction pioneer, social reformer, evolutionary biologist and historian H. G. Wells, dating from the period of 1936–38. Throughout the book, Wells describes his vision of the world brain: a new, free, synthetic, authoritative, permanent "World Encyclopaedia" that could help world citizens make the best use of universal information resources and make the best contribution to world peace. Development of the idea[edit] World Encyclopedia[edit] Wellsian dream of World Brain was first expressed in a lecture delivered at the Royal Institution of Great Britain, Weekly Evening Meeting, Friday, 20 November 1936. My particular line of country has always been generalization of synthesis. He wished the world to be such a whole "as coherent and consistent as possible."

Health - Why we want to feast on food As the holiday season approaches, Tom Stafford looks at overindulgence, and explains how our minds tell us we want something even if we may not like it. Ah, Christmas, the season of peace, goodwill and overindulgence. If this year is like others, I’ll probably be taking up residence on the couch after a big lunch, continuing to munch my way through packets of unhealthy snacks, and promising myself that I’ll live a more virtuous life once the New Year begins. It was on one such occasion that I had an epiphany in the psychology of everyday life. I’d just finished the last crisp of a large packet, and the thought occurred to me that I don’t actually like crisps that much. But there I was, covered in crumbs and post-binge guilt, saturated fats coursing through my body looking for nice arteries to settle down on. Every bite seemed essential, but in a way that seem to suggest I was craving them rather than liking them. Normally wanting and liking are tightly bound together. Pleasure principles

Metaman Metaman: The Merging of Humans and Machines into a Global Superorganism (ISBN 067170723X) is a 1993 book by author Gregory Stock. The title refers to a superorganism comprising humanity and its technology. While many people have had ideas about a global brain, they have tended to suppose that this can be improved or altered by humans according to their will. Colloque sur le "dialogue" entre psychanalyse et neurosciences Le programme de ce colloque de Perspectives Psy en dit long sur la nature du "dialogue" entre la psychanalyse et les neurosciences. J'ai envoyé le message ci-dessous aux organisateurs du colloque le 24/10/2012, malheureusement je n'ai à ce jour (le 12/12/2012) obtenu aucune réponse. Je le porte donc à la connaissance du public. Madame, Messieurs, Le programme du colloque « Dialogue Psychanalyse et Neurosciences » m’a été transmis et m’a beaucoup surpris par la discordance apparente entre le titre et le programme.
