Pour vivre centenaire, il faut un bon cerveau
Ce sont les propos de Françoise Forette, professeur de gériatrie à l’université Paris-V et directrice de la Fondation nationale de gérontologie, relevés par Anne Jouan, journaliste au Figaro. Dans un article publié en ligne le 16 Avril 2009, la journaliste explore de nouvelles recettes pour devenir centenaires.
Je me suis vue sourire en lisant cette citation: “pour vivre centenaire, il faut un bon cerveau!” Mais bon comment? L’article ouvre néanmoins sur un domaine de recherche extrêmement pertinent: le pouvoir de notre psychisme sur notre espérance de vie.
brain on a chip ?
How does the human brain run itself without any software? Find that out, say European researchers, and a whole new field of neural computing will open up. A prototype “brain on a chip” is already working. “We know that the brain has amazing computational capabilities,” remarks Karlheinz Meier, a physicist at Heidelberg University. “Clearly there is something to learn from biology. I believe that the systems we are going to develop could form part of a new revolution in information technology.”
It’s a strong claim, but Meier is coordinating the EU-supported FACETS project which brings together scientists from 15 institutions in seven countries to do just that. Inspired by research in neuroscience, they are building a ‘neural’ computer that will work just like the brain but on a much smaller scale.
Scientists at Work
In a small and dark laboratory at the Picower Institute in Cambridge, Massachusetts, a rat sits comfortably in a shine black plastic box. His long white and massive tail impress the visitors. He looks like a hybrid animal coming out of a Star Trek picture. A small metal chip implanted into his minuscule brain delicately deforms his scalp. Through that implant, scientists can record his neurons activity.
