CNRS INSIS - Un neurone artificiel mille fois plus économe en énergie qu’un neurone biologique

New Artificial Synapse Bridges the Gap to Brain-Like Computers. Science News, Webinars and Virtual Events. There is quite a bit of science fiction out there where mankind and machines fuse together to form one being.

Science News, Webinars and Virtual Events

This might sound a lot like the Terminator movies, but as we move to a future with advanced technology, it's becoming less and less like science "fiction" and more like science. Neural lace might hold the answer to taking some of the first baby steps into interfacing with our brains. Des synapses électroniques capables d'apprendre : vers un cerveau artificiel ? S'inspirer du fonctionnement du cerveau pour concevoir des machines de plus en plus intelligentes, telle est l'idée du biomimétisme.

Le principe est déjà à l'œuvre en informatique via des algorithmes pour la réalisation de certaines tâches comme la reconnaissance d'image. C'est ce qu'utilise Facebook pour identifier des photos par exemple. Mais le procédé est très gourmand en énergie. Apprendre comme dans Matrix n'est plus une fiction. The problem with fMRI. iStock On TV and in movies, we’ve all seen doctors stick an X-ray up on the lightbox and play out a dramatic scene: “What’s that dark spot, doctor?”

The problem with fMRI

“Hm…” In reality, though, a modern medical scan contains so much data, no single pair of doctor’s eyes could possibly interpret it. The brain scan known as fMRI, for functional magnetic resonance imaging, produces a massive data set that can only be understood by custom data analysis software. Scientists Connect Brain to a Basic Tablet—Paralyzed Patient Googles With Ease. For patient T6, 2014 was a happy year.

That was the year she learned to control a Nexus tablet with her brain waves, and literally took her life quality from 1980s DOS to modern era Android OS. A brunette lady in her early 50s, patient T6 suffers from amyotrophic lateral sclerosis (also known as Lou Gehrig’s disease), which causes progressive motor neuron damage. Mostly paralyzed from the neck down, T6 retains her sharp wit, love for red lipstick and miraculous green thumb. Harvard creates brain-to-brain interface, allows humans to control other animals with thoughts alone.

Researchers at Harvard University have created the first noninvasive brain-to-brain interface (BBI) between a human… and a rat.

Harvard creates brain-to-brain interface, allows humans to control other animals with thoughts alone

Simply by thinking the appropriate thought, the BBI allows the human to control the rat’s tail. This is one of the most important steps towards BBIs that allow for telepathic links between two or more humans — which is a good thing in the case of friends and family, but terrifying if you stop to think about the nefarious possibilities of a fascist dictatorship with mind control tech.

Animal Brains Networked Into Organic Computer ‘Brainet’ - Singularity HUB. Imagine a future where computers no longer run on silicon chips.

The replacement? Brains. Thanks to two separate studies recently published in Scientific Reports, we may be edging towards that future. In a series of experiments, scientists connected live animal brains into a functional organic computer. Scientists Create Artificial Neuron that Functions Like the Real Thing. It seems that growing miniature brains in the lab just wasn’t good enough for neuroscientists, as a group of researchers have now constructed an artificial neuron that works like the real thing.

Scientists Create Artificial Neuron that Functions Like the Real Thing

Amazingly, the fake cell manages to capture the fundamental signal-transmitting function of neurons and can communicate with real human cells, all in the absence of any living parts. But there is more to the idea behind this synthetic neuron than simply proving that it can be done. The team reckons that in the future, it might be possible to actually use these devices in patients to replace damaged nerves, for example, to help treat injury or disease. Mind-Reading Computer Writes Words with Brain Waves. Imagine a world in which authors can write books in days, not months, using only the power of their minds. This hands-free future could be around the corner: scientists have created software that hooks up to your brainwaves and transcribes whatever you're thinking. Brain-to-Text is the software behind this futuristic, sci-fi-style concept. It has the potential to transform the lives of those who have lost the ability to communicate effectively.

Stephen Hawking, for example, often has to scroll through letters of the alphabet one at a time while typing out messages. 20 billion nanoparticles talk to the brain using electricity - health - 08 June 2015. Electricity is the brain's language, and now we can speak to it without wires or implants. Nanoparticles can be used to stimulate regions of the brain electrically, opening up new ways to treat brain diseases. It may even one day allow the routine exchange of data between computers and the brain. A material discovered in 2004 makes this possible. Closer to AI: Electronic Long-Term Memory Cells Mirror Human BrainTrending. Memory is one of the more complex functions of the human brain. Leaving alone the debate about the accuracy of memory and the perceptual and psychological aspects of it, for purposes of this article let’s focus simply on the human brain’s ability to store and process multiple information threads simultaneously.

NeuroLex. New Alzheimer’s treatment fully restores memory function. Australian researchers have come up with a non-invasive ultrasound technology that clears the brain of neurotoxic amyloid plaques - structures that are responsible for memory loss and a decline in cognitive function in Alzheimer’s patients. If a person has Alzheimer’s disease, it’s usually the result of a build-up of two types of lesions - amyloid plaques, and neurofibrillary tangles.

Amyloid plaques sit between the neurons and end up as dense clusters of beta-amyloid molecules, a sticky type of protein that clumps together and forms plaques. Neurofibrillary tangles are found inside the neurons of the brain, and they’re caused by defective tau proteins that clump up into a thick, insoluble mass. This causes tiny filaments called microtubules to get all twisted, which disrupts the transportation of essential materials such as nutrients and organelles along them, just like when you twist up the vacuum cleaner tube.

Researchers may be able to improve memory by discharging magnetic pulses on the skull to alter the neural activity at and beneath the brain’s surface. ANDRZEJ KRAUZEWhen something goes wrong with neurons located deep in the brain, options for treatment are limited. Directly stimulating the neurons can be effective, but cutting through brain tissue to implant the necessary electrodes is risky. And magnetic or electrical pulses applied to the skull only reach the brain’s outermost regions. But the highly networked nature of the brain presents another possibility: noninvasively alter the activity of the neurons at the brain’s surface to indirectly affect the deeper brain regions they’re connected to. New System Lets Humans Control Mouse Genes With Their Thoughts.

Scientists have been able to tinker with the genes of other organisms for some time now—that’s nothing new. But controlling genes in another animal using only your thoughts? Sounds a rather insane idea that wouldn’t be out of place in a Sci-Fi movie, but it turns out it’s now possible, thanks to a newly-developed mind-controlled system. As described in the journal Nature Communications, the system works by using brain waves from human participants to activate a light inside a mouse’s brain, which then switches on a particular set of genes. This marks the first time that synthetic biology has been linked to the mind, and the authors believe this work could lead to the development of novel ways to treat medical conditions.

Paralysés : bientôt des neuroprothèses pour restaurer le mouvement. C'est une petite vidéo qui, en 2012, a fait le tour du monde (voir ci-dessous).

On y voyait une femme paralysée commander par la pensée (et grâce à des électrodes implantées dans son cerveau) un bras robotisé. L'appareil saisissait une bouteille munie d'une paille et lui apportait le tout au niveau de sa bouche. C'était la première fois en seize ans qu'elle pouvait boire seule. Quelques années plus tôt, grâce au même type d'interface cerveau-machine, un tétraplégique avait pu déplacer avec précision un curseur sur un écran d'ordinateur. On peut espérer qu'à terme, les recherches sur ces interfaces puissent restituer une certaine autonomie aux personnes paralysées. La grande difficulté de cette technique tient au fait que, même si l'on ne s'en aperçoit pas, la plupart des gestes courants mettent en jeu plusieurs muscles.
