Two experimental brain-machine technologies — deep brain stimulation coupled with physical therapy and a thought-controlled computer system—may offer new therapies for people with stroke and brain injuries, new human research shows.
In addition, an animal study shows a new artificial retina may restore vision better than existing prosthetics. The findings were announced today at Neuroscience 2010, the annual meeting of the Society for Neuroscience and the world's largest source of emerging news on brain science and health.
Brain-machine interface is an emerging field of neuroscience that aims to translate basic neuroscience research on how the brain packages and processes information to develop devices that help people regain functions lost to disease or injury.
Today's new findings show that:
Researchers have developed a faster, more accurate way to control cursors with thoughts alone. This scientific advance gives "real-time" feedback of brain activity and may provide more therapeutic options to people with brain injuries or syndromes that limit communication abilities (Anna Rose Childress, PhD, abstract 887.27, see attached summary).
Brain stimulation and physical therapy restores the use of paralyzed limbs — at least temporarily — in people recovering from a stroke. Few people recover completely after a stroke, and the new method may help in developing therapies to increase range of motion in affected limbs (Satoko Koganemaru, MD, PhD, abstract 898.5, see attached summary).
Scientists have constructed an artificial retina that incorporates the signals the eye normally sends to the brain. The new prosthetic may be capable of reproducing normal vision more effectively than existing technologies (Sheila Nirenberg, PhD, abstract 20.1, see attached summary).
"Harnessing the brain's ability to process, decode, and utilize information has untold therapeutic possibilities," said press conference moderator Miguel A. Nicolelis, MD, PhD, of Duke University and an expert in neurotechnology and brain-computer interfaces. "Today's research advances clearly demonstrate neuroscience's ability to expand our understanding of how the brain works, and translate that knowledge into better treatments, therapies, and technologies."
This research was supported by national funding agencies, such as the National Institutes of Health, as well as private and philanthropic organizations.

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
