Home News Health Mind Daily news 31 July 2018 By Alison GeorgeA boy who had a large portion of his brain removed to relieve his severe epilepsy is still able to function normally, showing how adaptable our brains can be. The boy started having seizures at the age of four. No treatments could stop his epilepsy, so as a last resort surgeons removed a third of his brain’s right hemisphere just before his seventh birthday. This “lobectomy” surgery removed his entire occipital lobe, which carries out visual processing, and most of his temporal lobe, which processes visual and auditory information. Researchers wanted to find out how the boy’s brain would recover after losing one of its visual centres – we usually have two, one in each of the brain’s hemispheres. A key question was what would happen to the boy’s “higher order” visual capabilities, such as being able to recognise faces and objects … [Read more...] about Boy’s brain works just fine after a large piece was removed
Tech & Science neuroscience A new study has brought researchers one step closer to better understanding the brain by revealing one of the simplest yet most puzzling dilemmas, how water in our blood gets to the brain. Understanding this could help scientists also figure out how to get water out of the brain in cases where excess water on the brain causes too much pressure. The study, published online in Nature Communications this month, used mice models to finally figure out how water is transported to the brain. For their research, the team inhibited the water transporters in the brains of live mice by breeding mice that did not have the conditions required for water transportation in the brain, Science Alert reported. This revealed that a previously unknown ion transporter named the NKCC1 co-transporter was responsible for most of the water transportation into the brain. The researchers hope that understanding how water gets into the brain could help … [Read more...] about Scientists Still Don’t Know How the Brain Works, but They Are Getting Closer

And when John Prine thinks about things, people want to hear what he has to say. That's why Prine will never join some past-their-prime legends who flounder as they try to recapture old magic. The way his brain works is just too interesting. On "Tree of … [Read more...] about Review: The way John Prine’s brain works keeps him relevant
The third dimension has been explored by 3D enthusiasts way back in the early 20th century when the first stereoscopic films appeared, but it wasn't until recently that 3D took the spotlight with an array of TV sets, portable game consoles and most recently phones. The 3D hype is still in its early days, but more and more people are considering the option. But honestly – always watching TV with the glasses? If you are not 15, chances are you tried watching a 3D movie at home for half an hour, shrugged your shoulders and took off the damn glasses to never try it again. There should be a better way! And mobile technology has it, but just how does it work? Currently, there are only a few gadgets featuring glasses-free (also called autostereoscopic) 3D displays. The LG Optimus 3D and the Nintendo 3DS are probably the most popular ones and both use a special screen technology called parallax barrier. The 3DS even allows for gradual control of just how much of a 3D effect you want. In … [Read more...] about 3D: How does it work?
Your three-pound brain runs on just 20 watts of power—barely enough to light a dim bulb. Yet the machine behind our eyes has built civilizations from scratch, explored the stars, and pondered our existence. In contrast, IBM’s Watson, a supercomputer that runs on 20,000 watts, can outperform humans at calculation and Jeopardy! but is still no match for human intelligence. WIRED OPINION ABOUT James J. DiCarlo, MD/PhD, is a professor of neuroscience, an investigator in the McGovern Institute for Brain Research and the Center for Brains, Minds and Machines, and the head of the department of Brain and Cognitive Sciences at the Massachusetts Institute of Technology. Neither Watson, nor any other artificially “intelligent” system, can navigate new situations, infer what others believe, use language to communicate, write poetry and music to express how it feels, and create math to build bridges, devices, and life-saving medicines. Why not? The society that solves the … [Read more...] about To Advance Artificial Intelligence, Reverse-Engineer the Brain
