Human Brain Project : en 2023, le cerveau humain simulé sur ordinateur Un processeur peut simuler le comportement d'un neurone. Mais le cerveau humain en contient sans doute environ 1011 et le nombre de connexions (ou synapses) est – vaguement – estimé à 1014 ou 1015... © EFPL /Human Brain Project Human Brain Project : en 2023, le cerveau humain simulé sur ordinateur - 1 Photo Parcourez notre dossier complet sur le cerveau Pour étudier les galaxies ou les systèmes planétaires, les astrophysiciens ont pris l’habitude de faire tourner des modèles informatiques. Pourquoi ne pas faire de même pour le cerveau humain ? Avec les ordinateurs de l’époque, rappelle aujourd’hui Henry Markram, il fallait la puissance d’un processeur de PC pour simuler un seul neurone. Selon Henry Markram, il faudrait 1.000 petaflops (1018 flops, soit 1 exaflops), alors que le champion du monde actuel (le chinois Tianhe-1A) en est à 2,7 et que la prochaine version de l’IBM Blue Gene n’en atteindra que 10.

Transformer des rêves en images bientôt possible ? Jusqu'ici, c'était de la science-fiction : un ordinateur qui lit directement dans le cerveau. Mais il arrive. Au laboratoire de calcul en neurosciences ATR, un groupe de chercheurs nippons ont franchi une étape essentielle : ils sont arrivés à reconstruire une image en noir et blanc à partir de ce que voyait un sujet. Tout commence avec un scanner IRM, qui sert à enregistrer l'activité du cerveau en surveillant les flux sanguins dans le cortex visuel. Enfin, on a continué à enregistrer leur activité en leur montrant des lettres. Le bilan n'est certes pas très précis. Applications variées... à inventer Les poètes penseront en priorité à enfin visualiser leurs rêves, au risque de les trouver encore plus absurdes une fois éveillés, mais les esprits pratiques peuvent y voir le meilleur détecteur de mensonges jamais imaginé ou un système parfait pour créer un portrait-robot.
Pierre Teilhard de Chardin Un article de Wikipédia, l'encyclopédie libre. Pour les articles homonymes, voir Chardin. Pierre Teilhard de Chardin Théologien, philosophe, géologue et paléontologue Théologie et philosophie du XXe siècle Pierre Teilhard de Chardin. Pierre Teilhard de Chardin ([tɛ.jaʁ.də.ʃaʁ.dɛ̃]) [1], ( , Orcines - , New York) est un jésuite, chercheur, paléontologue, théologien et philosophe français. Dans Le Phénomène humain, il trace une histoire de l'Univers, depuis la pré-vie jusqu'à la Terre finale, en intégrant les connaissances de son époque, notamment en mécanique quantique et en thermodynamique. Éléments de biographie[modifier | modifier le code] En 1912, il rejoint le Muséum d'histoire naturelle de Paris et y collabore avec Marcellin Boule, paléontologue qui avait étudié le premier squelette entier d'un homme de Néandertal et dont il devient un ami. En 1916, il écrit son premier essai, La Vie Cosmique, et en 1919, Puissance spirituelle de la Matière, essais qui annoncent son œuvre plus tardive.
Article of the Month Page by Robert Dilts. A fractal is a complex geometric pattern that can be subdivided in parts, each of which is (at least approximately) a smaller copy of the whole. Fractals are generally "self-similar" (the bits look like the whole) and independent of scale (they look similar, no matter how close you zoom in). The Fractal Dragon (Benoit B. Many mathematical structures are fractals; e.g. the Sierpinski triangle, Koch snowflake, Peano curve, Mandelbrot set and Lorenz attractor. Set three points (A, B and C). What pattern do you think will emerge? The following graphic was created by a computer program applying the above instructions (known as the Sierpinski triangle): The Sierpinski Triangle From an NLP perspective, fractals are a good example of how a simple process at the level of deep structure can generate a complex pattern at the level of surface structure. Descriptions of generative processes are typically more "code congruent" than descriptions of the resulting content.
Noos This article is about a philosophical term. For the philosophy journal, see Noûs. In philosophy, common English translations include "understanding" and "mind"; or sometimes "thought" or "reason" (in the sense of that which reasons, not the activity of reasoning).[2][3] It is also often described as something equivalent to perception except that it works within the mind ("the mind's eye").[4] It has been suggested that the basic meaning is something like "awareness".[5] In colloquial British English, nous also denotes "good sense", which is close to one everyday meaning it had in Ancient Greece. This diagram shows the medieval understanding of spheres of the cosmos, derived from Aristotle, and as per the standard explanation by Ptolemy. It came to be understood that at least the outermost sphere (marked "Primũ Mobile") has its own intellect, intelligence or nous - a cosmic equivalent to the human mind. Pre-Socratic usage[edit] The first use of the word nous in the Iliad. Xenophon[edit]
Psychoneuroimmunology The word "biofeedback" was coined in the late 1960s to describe laboratory procedures then being used to train experimental research subjects to alter brain activity, blood pressure, heart rate, and other bodily functions that are not normally controlled voluntarily. The most common forms of biofeedback today are the electromyographic (EMG) and the electrodermal (EDR). These sensors allow the person to monitor their own muscle relaxation, heart rate, breathing patterns and perspiration and concentrate on changing it through either the visual or auditory information provided by the equipment. In initial studies, some scientists believed that a day might come when biofeedback would provide a major degree of control over our bodies. With people exerting their "will" they thought it might be possible to change the patterns of our brainwaves to create healing without drugs which produce often unpleasant side affects for patients with high blood pressure. Conclusion:
Law of Complexity/Consciousness The Law of Complexity/Consciousness is the postulated tendency of matter to become more complex over time and at the same time to become more conscious. The law was first formulated by Jesuit priest and paleontologist Pierre Teilhard de Chardin. Teilhard holds that at all times and everywhere, matter is endeavoring to complexify upon itself, as observed in the evolutionary history of the Earth. Matter complexified from inanimate matter, to plant life, to animal life, to human life. Or, from the geosphere, to the biosphere, to the noosphere (of which humans represented, because of their possession of a consciousness which reflects upon themselves). For Teilhard, the Law of Complexity/Consciousness continues to run today in the form of the socialization of mankind. Teilhard imagines a critical threshold, the Omega Point, in which mankind will have reached its highest point of complexification (socialization) and thus its highest point of consciousness.

Forget IQ, Collective Intelligence is the New Measure of Smart (video We may focus on the stories of individual genius, but it will be harnessing the intelligence of the collective that enables humanity to solve its future problems. Do you know your IQ, that little number that’s supposed to measure how smart you are? Forget it. Individual intelligence is old news, collective intelligence (CI) is the future. And it’s already here. Google lets you access the collective records of the world via internet searches. Collective intelligence can include distributed computing. Another reason why CI will dominate IQ is that individual intelligence is subsumed by the collective. To this end, CCI at MIT is working to understand and guide collective intelligence. Collective intelligence can also take the form of collective art or creativity. Kim-Ung Yong might be the world’s smartest man, his IQ is reportedly 210. [sources: Indiana University, CCI at MIT]
