Mind Monitoring via Mobile Brain-body Imaging

'..Surprisingly, however, there has been little serious effort to concurrently record the behavior the brain is controlling with anything near the same bandwidth. In human brain experiments, behavior is most often recorded only in the form of a sparse series of minimal finger button presses – giving an effective rate of behavioral data collection near 1 bit/sec..'

Current brain-computer interface (BCI) research attempts to estimate intended operator body or cursor movements from his/her electroencephalographic (EEG) activity alone.

More general methods of monitoring operator cognitive state, intentions, motivations, and reactions to events might be based on continuous monitoring of the operator’s (EEG) as well as his of her body and eyemove... more »

A Wearable Remote Brain Machine Interface using Smartphones and the Mobile Network

'..smart phones as a data relay for EEG/EOG data analysis. The smartphone also acts as a computational platform to infer human intent. The inferred intent is registered as a human gesture or action at a backend server. The server can be used to control devices at any geographic location. We have designed, implemented, and evaluated our fully functional RBM interface and demonstrate it efficacy in remotely controlling robotic elements..'

A Remote Brain Machine Interface (RBMI) can be defined as a means to control a machine that is in a different geographical location than the user.

Thus far, simulations for such interfaces using multiple channels of non-invasive EEG signals acquired through tethered systems have... more »

"The project will dramatically facilitate and promote future research into white matter structure and function. Historically in neuroscience, the vast majority of research effort has been invested in understanding and studying gray matter and neurons, while white matter has received relatively little attention.

This owes largely to the lack of effective research tools to study white matter, even though it comprises about half the volume of the brain. The new MRI methods that were developed in CONNECT allow researchers, for the first time, to visualize the micro-structure of the living brain over the whole brain."

Exposing The Truth
Psychiatrists Drugging Children for 'Social Justice'

It’s the latest thing. Psychiatrists are now giving children in poor neighborhoods Adderall, a dangerous stimulant, by making false diagnoses of ADHD, or no diagnoses at all. Their aim? To “promote social justice,” to improve academic performance in school.

The rationale is, the drugged kids will now be able to compete with children from wealthier families who attend better schools. Leading the way is Dr. Michael Anderson, a pediatrician in the Atlanta area. Incredibly, Anderson told the New York Times his diagnoses of ADHD are “made up,” “an excuse” to hand out the drugs.

“We’ve decided as a society that it’s too expensive to modify the kid’s environment. So we have to modify the kid,” Anderson said.

It would be hard to find a clearer mission statementfrom a psychiatrist: mi... more »

"Graphene and MoS2 are just the beginning of a new realm of research on two-dimensional materials. It's the most exciting time for electronics in the last 20 or 30 years. It's opening up the door to a completely new domain of electronic materials and devices."

"Like graphene, itself a 2-D form of graphite, molybdenum disulfide has been used for many years as an industrial lubricant. But it had never been seen as a 2-D platform for electronic devices until last year, when scientists at the Swiss university EPFL produced a transistor on the material."

Because it already is widely produced as a lubricant, and thanks to ongoing work at MIT and other labs on making it into large sheets, scaling up production of the material for practical uses should be much easier than with other new materials.

Researchers were able to fabricate a variety of basic... more »

Book written in DNA code. Scientists who encoded the book say it could soon be cheaper to store information in DNA than in conventional digital devices

"Scientists have for the first time used DNA to encode the contents of a book. At 53,000 words, and including 11 images and a computer program, it is the largest amount of data yet stored artificially using the genetic material.

The resea
rchers claim that the cost of DNA coding is dropping so quickly that within five to 10 years it could be cheaper to store information using this method than in conventional digital devices.

Deoxyribonucleic acid or DNA – the chemical that stores genetic instructions in almost all known organisms – has an impressive data capacity. One gram can store up to 455bn gigabytes: the contents of more than 100bn DVDs, making it the ultimate in compact storage media.

The optimal calibration hypothesis: how life history modulates the brain's social pain network

'..People are driven to seek out and maintain positive relationships with others through a fundamental need to belong, which is pervasive across time and cultures. This fundamental motivation toward belongingness is deep-seated in human evolutionary history..'

A growing body of work demonstrates that the brain responds similarly to physical and social injury. Both experiences are associated with activity in the dorsal anterior cingulate cortex (dACC) and anterior insula. This dual functionality of the dACC and anterior insula underscores the evolutionary importance of maintaining interpersonal bonds.

Despite the weight that evolution has placed on social injury, the pain response... more »

Scientists Create First Quantum Network : Two Atoms

Scientists at the Max Planck Institute of Quantum Optics in Garching, Germany have successfully created the world’s first quatum network. A team of scientists led by Professor Gerhard Rempe, director at the institute and head of the Quantum Dynamics devision, set up the first elementary quantum network by coupling single-atom nodes that communicate quantum information via the coherent exchange of single photons. These nodes are prerequisites for functional quantum networks, as they allow for the reversible exchange of quantum information.

The milestone passed today was the connecting of two of these single-atom systems, and the exchange of quantum information between them. The scientists hope these single-atom-cavity nodes can be used in networks of larger size, and hope they will improve upon the performance and usefulnesso... more »

Stunning new visuals of the brain reveal a deceptively simple pattern of organization in the wiring of this complex organ.

Instead of nerve fibers travelling willy-nilly through the brain like spaghetti, as some imaging has suggested, the new portraits reveal two-dimensional sheets of parallel fibers crisscrossing other sheets at right angles in a gridlike structure that folds and contorts with the convolutions of the brain.

This same pattern appeared in the brains of humans, rhesus monkeys, owl monkeys, marmosets and galagos, researchers report today.

Astounding George Dyson interview on the hybridizing of digital code and genetic code

“It's a very symbiotic relationship: the same way life found a way to use the self-replicating qualities of these polynucleotide molecules to the great benefit of life as a whole, there's no reason life won't use the self-replicating abilities of digital code, and that's what's happening. If you look at what people like Craig Venter and the thousand less-known companies are doing, we're doing exactly that, from the bottom up.“

Scientists Hijack Mouse Neurons to Take Control of Their Memories
In a new study with powerful implications for mental health, scientists hijacked the memories of lab mice, inducing them to form synthetic "hybrid memories" that were a combination of real experience and confused context. The work could eventually pave the way for false-memory or real memory manipulation in people with schizophrenia or post-traumatic stress disorder. Mental health disorders like schizophrenia are associated with false memories or crippling fears - a drug that turns off this response in the right neurons could help patients live healthier lives.http://www.popsci.com.au/science/scientists-hijack-mouse-neurons-to-take-control-of-their-memories

Can the Reason Rally resonate in this most religious of democracies? [The Guardian] In the US, where just one member of Congress is openly atheist, the secular movement needs to 'come out'. And now is the time. [..] Despite the growing number of Americans who identify their religion as "none", our politics are still dominated by supercharged religious talk. But this past weekend, in a sort of coming out party, atheists and other non-believers gathered on the National Mall last Saturday for the first-ever Reason Rally. It was their way of saying, "We're here! We're queer! Get used to it!"

Highly Flexible Despite Hard-Wiring: Even Slight Stimuli Change the Information Flow in the Brain

Your brain is so impressive - treasure it.

One cup or two faces? What we believe we see in one of the most famous optical illusions changes in a split second; and so does the path that the information takes in the brain. In a new theoretical study, scientists of the Max Planck Institute for Dynamics and Self-Organization, the Bernstein Center Göttingen and the German Primate Center now show how this is possible without changing the cellular links of the network. The direction of information flow changes, depending on the time pattern of communication between brain areas. This reorganisation can be triggered even by a slight stimulus, such as a scent or sound, at the right time.

[...]According to the new model, when a photon of light from the Sun is absorbed by a special molecule in the bird's eye, it can cause an electron to be kicked from its normal state into an alternative location a few nanometres away. Until the electron eventually relaxes back, it creates an ‘electric dipole field’ which can augment the bird's vision - for example altering colours or brightness. Crucially, the alignment of the molecule compared to the Earth's magnetic field controls the time it takes for the electron to relax back, and so controls the strength of the effect on the bird's vision.[...]

Scientists claim brain memory code cracked

Despite a century of research, memory encoding in the brain has remained mysterious. Neuronal synaptic connection strengths are involved, but synaptic components are short-lived while memories last lifetimes. This suggests synaptic information is encoded and hard-wired at a deeper, finer-grained molecular scale.

We all know who the Mario Brothers are but have you ever stepped back and tried looking at those games from a fresh perspective? Like you've never seen or heard of them before? They're bananas! There are armored turtles who stand on their hind legs and steal princesses! There are bullets with FACES! We make a case for Mario's inclusion into a canon of art wider than "Video Game": we think Mario is a piece of surrealist artwork.
