    Allo,

    Comme le dit le titre

    Semble-t-il qu'il y aurait un projet similaire dans les cartons du NIH. L'argumentation économique est intéressante.

    In his State of the Union address, President Obama cited brain research as an example of how the government should “invest in the best ideas.”

    “Every dollar we invested to map the human genome returned $140 to our economy — every dollar,” he said. “Today our scientists are mapping the human brain to unlock the answers to Alzheimer’s. They’re developing drugs to regenerate damaged organs, devising new materials to make batteries 10 times more powerful. Now is not the time to gut these job-creating investments in science and innovation.”

    Story C. Landis, the director of the National Institute of Neurological Disorders and Stroke, said that when she heard Mr. Obama’s speech, she thought he was referring to an existing National Institutes of Health project to map the static human brain. “But he wasn’t,” she said. “He was referring to a new project to map the active human brain that the N.I.H. hopes to fund next year.”

    Indeed, after the speech, Francis S. Collins, the director of the National Institutes of Health, may have inadvertently confirmed the plan when he wrote in a Twitter message: “Obama mentions the #NIH Brain Activity Map in #SOTU.”

    A spokesman for the White House Office of Science and Technology Policy declined to comment about the project.

    The initiative, if successful, could provide a lift for the economy. “The Human Genome Project was on the order of about $300 million a year for a decade,” said George M. Church, a Harvard University molecular biologist who helped create that project and said he was helping to plan the Brain Activity Map project. “If you look at the total spending in neuroscience and nanoscience that might be relative to this today, we are already spending more than that. We probably won’t spend less money, but we will probably get a lot more bang for the buck.”

    Scientists involved in the planning said they hoped that federal financing for the project would be more than $300 million a year, which if approved by Congress would amount to at least $3 billion over the 10 years.

    Re : Human brain Project est financé

    Le projet en question est le Brain Activity Map Project.

    Quelques extraits du texte:

    Understanding how the brain works is arguably one of the greatest scientific challenges of our time. Although there have been piecemeal efforts to explain how different brain regions operate, no general theory of brain function is universally accepted. A fundamental underlying limitation is our ignorance of the brain's microcircuitry, the synaptic connections contained within any given brain area, which Cajal referred to as “impenetrable jungles where many investigators have lost themselves”
    (...)
    To elucidate emergent levels of neural circuit function, we propose to record every action potential from every neuron within a circuit—a task we believe is feasible.
    (...)
    To achieve this vision, one clearly needs to develop novel technologies.
    (...)
    Optical techniques are minimally invasive and can provide great spatial and temporal flexibility, have single-cell resolution, and can be applied to living preparations, even awake behaving ones (Helmchen et al., 2011).
    (...)
    Novel voltage sensors with better signal-to-noise, less photodamage, and faster temporal resolution are needed. Continued improvements are being made in voltage indicators, and particularly promising are nanoparticles, small inorganic compounds that have large absorption and highly efficient emission. These are robust during extended illumination and can be very sensitive to the external electric field. Zero-dimensional nanoparticles, i.e., quantum dots, could be directly used to measure voltage in neurons. Other nanoparticles, such as nanodiamonds (Mochalin et al., 2012), may provide an even higher sensitivity to magnetic and electric fields. In addition, by acting as “antennas” for light, nanoparticles can greatly enhance optical signals emitted by more traditional voltage reporters.
    (...)
    Electrical recording of neuronal activity is now becoming possible on a massively parallel scale by harnessing novel developments in silicon-based nanoprobes (Figure 2). Silicon-based neural probes with several dozen electrodes are already available commercially; it is now feasible to record from dozens of sites per silicon neural probe, densely, at a pitch of tens of μm (Du et al., 2009a). Stacking of two-dimensional multishank arrays into three-dimensional probe arrays would provide the potential for hundreds of thousands of recording sites. There are technical hurdles to be surmounted, but when the technology is perfected, recording from many thousands of neurons is conceivable with advanced spike-sorting algorithms. The “Holy Grail” will be to record from millions of electrodes, keeping the same bandwidth, reducing the electrode pitch down to distances of ∼15 μm, and increasing the probe length to cortical dimensions of several centimeters. This will require significant innovation in systems engineering.
    (...)
    We also envision techniques for wireless, noninvasive readout of the activity of neuronal populations (Figure 2). These might include wireless electronic circuits based on silicon very large-scale integration (VLSI), synthetic biological components, or their hybrids. It is easy to underestimate the potential of today's microelectronic technology, and we think that it will ultimately become feasible to deploy small wireless microcircuits, untethered in living brains, for direct monitoring of neuronal activity, although there are significant technological challenges.
    (...)
    To succeed, the BAM Project needs two critical components: strong leadership from funding agencies and scientific administrators, and the recruitment of a large coalition of interdisciplinary scientists. We believe that neuroscience is ready for a large-scale functional mapping of the entire brain circuitry, and that such mapping will directly address the emergent level of function, shining much-needed light into the “impenetrable jungles” of the brain.


    Encore plus cool que l'HBM, et très complémentaire

    Honnêtement, j'ai pas tout compris......pourquoi dis-tu que c'est encore mieux que l'HBM, leur projet?

    Re : Human brain Project est financé

    HBM c'est 500 millions à compléter d'autres sources, BAM ce serait 3 milliards cash

    Blague à part, HBM vise un modèle de cerveau générique construit à partir de briques élémentaires, alors que BAM vise le uploading de système nerveux fonctionnels de plus en plus grand. Les deux sont complémentaires en ce que les propriétés fonctionnelles émergentes découvertes par le HBM pourraient être vérifiée par les données collectées par le BAM, et inversement les propriétés fonctionnelles non élémentaires découvertes par le BAM pourraient être importés pour bonifier la construction du cerveau générique d'HBM.
