A maverick neuroscientist believes he has deciphered the code by which the brain forms long-term memories.
Theodore Berger, biomedicínský inženýr a neurolog v Los Angeles, si budoucnost pacientů s těžkou poruchou paměti představuje tak, že jí bude moci opět získat pomoc z elektronického implantátu. U lidí, jejichž mozek utrpěl poškození, mrtvici nebo Alzheimerova chorobu, narušení neuronální sítě často brání vytváření dlouhodobých vzpomínek. Již více než dvě desetiletí, Berger navrhuje křemíkové čipy napodobující signály, který tyto neurony vytvářeli, když řádně fungovali.
Researchers manipulate mouse neurons to create a false memory; the work could lead to a better understanding of how memories form.
Vědci vytvořili falešnou paměť u myší tím, že manipulují neurony, které nesou vzpomínku. Práce dále ukazuje, jak nespolehlivá paměť může být.
Jedním z dlouhodobých cílů práce, je být schopni identifikovat nové metody pro pomoc pacientům s kognitivními poruchami. "Není to protože chceme implantovat některé falešné zkušenosti do lidské mysli, ale protože by mohlo být užitečné, vyvinout nakonec metody ke snížení kognitivní abnormality spojené s psychickými chorobami, jako jsou bludy u pacientů se schizofrenií , "říká Tonegawa.
Researchers developed a neuromorphic system that can carry out complex sensorimotor tasks in real time. They demonstrate a task that requires a short-term memory and context-dependent decision-making.
They combined neuromorphic neurons into networks that implemented neural processing modules equivalent to so-called "finite-state machines". Behavior can be formulated as a "finite-state machine" and thus transferred to the neuromorphic hardware in an automated manner.

This thesis concerns drawing as a form of enquiry, figuration and knowledge, specifically relating to perceptions of the body and embodied experience. The primary method and object of research is the practice of direct mark-making in response to perceptual experience, here termed observational drawing. The skills and habits of this learnt practice have been destabilised: by attempting a phenomenological approach; by drawing faces and bodies in conditions of movement and change; by progressively subtracting elements of manual and visual control. Following from observational drawing, the creative research methodology incorporates other modes of drawing, re-working of scanned drawings, note-making, reading and writing. The thesis includes a written overview (Part I), and a digital archive of drawings (Part II), jointly comprising a narrative of the research process.
....MEMS stands for “microelectromechanical system” and are microscopic machines that replace the larger, bulkier, heavier and power sucking predecessors. MEMS is the same technology that has revolutionized mobility technologies like microphones, barometers, gyroscopes, and even electronic clocks.

What the Internet is doing to our brains

"Dave, stop. Stop, will you? Stop, Dave. Will you stop, Dave?” So the supercomputer HAL pleads with the implacable astronaut Dave Bowman in a famous and weirdly poignant scene toward the end of Stanley Kubrick’s 2001: A Space Odyssey. Bowman, having nearly been sent to a deep-space death by the malfunctioning machine, is calmly, coldly disconnecting the memory circuits that control its artificial “ brain. “Dave, my mind is going,” HAL says, forlornly. “I can feel it. I can feel it.”
With much of our attention focused the rise of advanced artificial intelligence, few consider the potential for radically amplified human intelligence (IA). It’s an open question as to which will come first, but a technologically boosted brain could be just as powerful — and just as dangerous – as AI.
As a species, we’ve been amplifying our brains for millennia. Or at least we’ve tried to. Looking to overcome our cognitive limitations, humans have employed everything from writing, language, and meditative techniques straight through to today’s nootropics. But none of these compare to what’s in store. Unlike efforts to develop artificial general intelligence (AGI), or even an artificial superintelligence (SAI), the human brain already presents us with a pre-existing intelligence to work with. Radically extending the abilities of a pre-existing human mind — whether it be through genetics, cybernetics or the integration of external devices — could result in something quite similar to how we envision advanced AI.
Looking to learn more about this, I contacted futurist Michael Anissimov, a blogger atAccelerating Future and a co-organizer of the Singularity Summit. He’s given this subject considerable thought — and warns that we need to be just as wary of IA as we are AI. The real objective of IA is to create super-Einsteins, persons qualitatively smarter than any human being that has ever lived. There will be a number of steps on the way there.
The first step will be to create a direct neural link to information. Think of it as a "telepathic Google." The next step will be to develop brain-computer interfaces that augment the visual cortex, the best-understood part of the brain. This would boost our spatial visualization and manipulation capabilities. Imagine being able to imagine a complex blueprint with high reliability and detail, or to learn new blueprints quickly. There will also be augmentations that focus on other portions of sensory cortex, like tactile cortex and auditory cortex. The third step involves the genuine augmentation of pre-frontal cortex. This is the Holy Grail of IA research — enhancing the way we combine perceptual data to form concepts. The end result would be cognitive super-McGyvers, people who perform apparently impossible intellectual feats. For instance, mind controlling other people, beating the stock market, or designing inventions that change the world almost overnight. This seems impossible to us now in the same way that all our modern scientific achievements would have seemed impossible to a stone age human — but the possibility is real.
For it to be otherwise would require that there is some mysterious metaphysical ceiling on qualitative intelligence that miraculously exists at just above the human level. Given that mankind was the first generally intelligent organism to evolve on this planet, that seems highly implausible. We shouldn't expect version one to be the final version, any more than we should have expected the Model T to be the fastest car ever built.
Latest experiments show how a silicon chip externally connected to rat and monkey brains by electrodes can process information just like actual neurons. Scientist demonstrated that they could also help monkeys retrieve long-term memories from a part of the brain that stores them.

Forget about robots rising up against humans for world domination.
In the future we’re all going to be robot-human hybrids with the help of wearable computers. We’ve already seen Google Glass, the search giant’s augmented-reality glasses, and now the latest Y Combinator startup to come out of stealth, Thalmic Labs, is giving us a wrist cuff that will one day control computers, smartphones, gaming consoles, and remote-control devices with simple hand gestures.
Unlike voice-detecting Google Glass, and the camera-powered Kinect and Leap Motion controller, Thalmic Labs is going to the source of your hand and finger gestures – your forearm muscles. “In looking at wearable computers, we realized there are problems with input for augmented-reality devices,” says Thalmic Labs co-founder Stephen Lake. “You can use voice, but no one wants to be sitting on the subway talking to themselves, and cameras can’t follow wherever you go.”
I’d argue that thanks to Bluetooth headsets and Siri, we’ve already been talking to ourselves for the last decade, so talking to my glasses isn’t a huge stretch. But, I won’t deny that it looks cool to casually flick my hand to change the song on my MacBook, which is what Thalmic Labs is promising with its $149 forearm gadget called the Myo (a nod to the Greek prefix for muscle, but rhymes with Leo), which has an adjustable band that can accommodate almost anyone.
