Computer model of the brain simulates daydreams

http://www.jneurosci.org/content/33/27/11239.abstract?sid=f2eef2ee-cad7-4d63-b90a-ac6566847078 Washington University researchers have created a computer model to help scientists learn how the brain’s anatomical structure contributes to the creation and maintenance of resting state networks.   They hope that the model will help them understand why certain portions of the brain work together when a person daydreams or is mentally idle, helping doctors better […]

Low cost GPU based neural network simulates the brain

http://stanford.edu/~acoates/papers/CoatesHuvalWangWuNgCatanzaro_icml2013.pdf In a new paper, Stanford’s Andrew Ng describes how to use graphics microprocessors to build a $20,000 computerized brain that is similar to the cat-detector he developed with Google last year for $1M. To test his hypothesis about GPU-driven Deep Learning, he also built a larger version of the platform for $100,000.  It utilized […]

Thought-controlled flying robot

http://www.livescience.com/27849-mind-controlled-devices-brain-awareness-nsf.html University of Minnesota researchers led by Professor Bin He have been able to control a small helicopter using only their minds, pushing the potential of technology that could help paralyzed or motion-impaired people interact with the world around them. An EEG cap with 64 electrodes was put on head of the person controlling the helicopter. […]

Nerve and muscle interfaces for prosthetic control

http://www.darpa.mil/NewsEvents/Releases/2013/05/30.aspx DARPA continues to build technology with academic partners to enable amputees to control prosthetic limbs with their minds.  Examples follow: Researchers at the Rehabilitation Institute of Chicago demonstrated a type of peripheral interface called targeted muscle re-innervation (TMR). By rewiring nerves from amputated limbs, new interfaces allow for prosthetic control with existing muscles. Researchers […]

Cornell robots anticipate human actions

http://news.cornell.edu/stories/2013/04/think-ahead-robots-anticipate-human-actions Cornell University researchers have programmed a PR-2 robot to not only carry out everyday tasks, but to anticipate human behavior and adjust its actions. From a database of 120 3-D videos of people performing common household activities, the robot has been trained to identify human activities by tracking the movements of the body – reduced […]

Eldercare robots perform essential tasks

http://bits.blogs.nytimes.com/2013/05/19/disruptions-helper-robots-are-steered-tentatively-to-elder-care/ Already popular in Japan, today’s New York Times reports on the developing trend of robotic companions for the elderly. A typical Japanese example is the Tsukuba University created Hybrid Assistive Limb. The battery-powered suit senses and amplifies the wearer’s muscle action when carrying or lifting heavy objects.  Caregivers can also use the suit to […]

Skin mounted electrode arrays measure neural signals

http://coleman.ucsd.edu/lab-research/ Professor Todd Coleman of UCSD is developing foldable, stretchable electrode arrays that can non-invasively measure neural signals. They can also provide more in-depth analysis by including thermal sensors to monitor skin temperature and light detectors to analyze blood oxygen levels.  The device is powered by micro solar panels and uses antennae to wirelessly transmit or […]

Brain-machine interface allows control of limbs through thoughts

http://www.fastcoexist.com/1681674/a-prosthetic-arm-controlled-by-your-thoughts By placing a small sensor in the brain’s motor cortex, interfaces can pick up on electrical activity, and translate it into commands that control a robotic arm. Now scientists have gone a step further. Instead of a wired brain-arm link, they have now developed a wireless connection powerful enough to work at a distance of […]
