Using a combination of microscopy methods, Harvard researchers have untangled part of the circuitry of the cerebral cortex, illuminating brain connections in 3-D. A new neural circuit model will allow researchers to crawl through the individual connections in a neural network.
Electrode implants which zap areas of the brain have mysteriously helped ease the symptoms of crippling diseases such as depression and Parkinson's. Now brain scans could help predict who exactly might benefit from deep brain stimulation (DBS), based on seeing which interconnected regions of the brain "light up" at the same time, New Scientist reports.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
