Super-entities are not just limited to dominance of the globe. Just as the economy is intertwined and largely controlled by a small and powerful core network, so too is your brain. Researchers have long known that some areas of the brain are deeply connected to other regions — but now a team from Indiana University and the Netherlands says these connected brain regions form strong connections to each other, creating a cerebral "rich club."
Pour a robot a glass of water, and you quench its thirst for a day. But teach a robot to pour a cup of water and you are somewhere on par with researchers at Tokyo Institute of Technology’s Hasegawa Group. Roboticists and software engineers there have implemented a kind of self-replicating neural technology into their robot that enables it not only to perform tasks but also to learn as it goes, integrating prior knowledge into new tasks and environments.
Electrical impulses sent to a paralyzed man’s spinal cord allow him to walk again, researchers say. Rob Summers, 25, can voluntarily move his feet and hips and walk on a treadmill with support, in what could be a major breakthrough for the treatment of paralysis.
Researchers testing mental illness figured out how to induce schizophrenic symptoms in a computer, causing it to place itself at the center of crazy delusions, such as claiming responsibility for a terrorist bombing. The results bolster a hypothesis that claims faulty information processing can lead to schizophrenic symptoms.
The burgeoning neural networks of fruit fly pupae solve a distributed computing problem, arranging sensory bristles in a very efficient, effective manner. Scientists who monitored the bristles‘ growth say they can mimic the flies’ method to build more effective communications networks.
Researchers at IBM have created the most complex neurological map ever seen, detailing the comprehensive long-distance network that makes up the macaque monkey brain in unprecedented detail. Such a roadmap through the brain's complex networking processes could have major implications for attempts at reverse-engineering neural networks and creating cognitive computer chips that "think" as powerfully and efficiently as the biological brain.
We often think of our blood as specifically tasked with carrying oxygen to our brains and other organs, but it's also a living fluid, changing up its duties in response to various stimuli. To better understand -- and anticipate -- one aspect of this complicated biology, researchers have trained a neural network computer to model how platelets in the blood react to complicated conditions like those experienced during heart attack or stroke.
