Conscious Brain-to-Brain Communication in Humans Using Non-Invasive Technologies

Posted by in categories: biotech/medical, computing, internet, neuroscience

Human sensory and motor systems provide the natural means for the exchange of information between individuals, and, hence, the basis for human civilization. The recent development of brain-computer interfaces (BCI) has provided an important element for the creation of brain-to-brain communication systems, and precise brain stimulation techniques are now available for the realization of non-invasive computer-brain interfaces (CBI). These technologies, BCI and CBI, can be combined to realize the vision of non-invasive, computer-mediated brain-to-brain (B2B) communication between subjects (hyperinteraction). Here we demonstrate the conscious transmission of information between human brains through the intact scalp and without intervention of motor or peripheral sensory systems. Pseudo-random binary streams encoding words were transmitted between the minds of emitter and receiver subjects separated by great distances, representing the realization of the first human brain-to-brain interface. In a series of experiments, we established internet-mediated B2B communication by combining a BCI based on voluntary motor imagery-controlled electroencephalographic (EEG) changes with a CBI inducing the conscious perception of phosphenes (light flashes) through neuronavigated, robotized transcranial magnetic stimulation (TMS), with special care taken to block sensory (tactile, visual or auditory) cues. Our results provide a critical proof-of-principle demonstration for the development of conscious B2B communication technologies. More fully developed, related implementations will open new research venues in cognitive, social and clinical neuroscience and the scientific study of consciousness. We envision that hyperinteraction technologies will eventually have a profound impact on the social structure of our civilization and raise important ethical issues.

Automatic Quantum Computer Programming: A Genetic Programming Approach

Posted by in categories: computing, genetics, quantum physics

Provides an introduction to quantum computing for non-physicists, as well as an introduction to genetic programming for non-computer-scientists. The book explores several ways in which genetic programming can support automatic quantum computer programming and presents detailed descriptions of specific techniques, along with several examples of their human-competitive performance on specific problems. Source code for the author’s QGAME quantum computer simulator is included as an appendix, and pointers to additional online resources furnish the reader with an array of tools for automatic quantum computer programming.

What makes a great qubit? Diamonds and ions could hold the answer

Posted by in categories: computing, quantum physics

At the core of quantum computing is the qubit. The best ones have a few defining traits, and scientists are looking to everything from lasers to Russian diamonds to help refine the best qubits for the next generation of quantum computing.

Universal memory achieved: Scientists patent energy saving ‘holy grail’ of computing

Posted by in category: computing

Scientists at Lancaster University have announced that they have invented an electronic memory device that realises the dream of universal memory – a previously hypothetical technology long considered to be revolutionary for the industry.

Universal memory is a computer data storage technology that until now has been purely conceptual, combining the speed and low cost of dynamic random-access memory (DRAM) and the stability of flash memory. This also would result in significantly lower power consumption.

It had been considered impossible by some in the field, but scientists at Lancaster University say that the electronic memory device they have invented and patented is the realisation of the universal memory dream.

Researchers demonstrate new path to reliable quantum computation

Posted by in categories: computing, information science, quantum physics

Researchers at the University of Chicago published a novel technique for improving the reliability of quantum computers by accessing higher energy levels than traditionally considered. Most prior work in quantum computation deals with “qubits,” the quantum analogue of binary bits that encode either zero or one. The new work instead leverages “qutrits,” quantum analogues of three-level trits capable of representing zero, one or two.

The UChicago group worked alongside researchers based at Duke University. Both groups are part of the EPiQC (Enabling Practical-scale Quantum Computation) collaboration, an NSF Expedition in Computing. EPiQC’s interdisciplinary research spans from algorithm and software development to architecture and design, with the ultimate goal of more quickly realizing the enormous potential of computing for scientific discovery and computing innovation.

Mind Over Matter: Cognitive Neuroengineering

Posted by in categories: biotech/medical, computing, engineering, neuroscience

I had a little more invested in BCI.


Brain-machine interface—once the stuff of science fiction novels—is coming to a computer near you. The only question is: How soon? While the technology is in its infancy, it is already helping people with spinal cord injuries. Our authors examine its potential to be the ultimate game changer for any number of neurodegenerative diseases, as well as behavior, learning, and memory.
