(PhysOrg.com) -- By implanting an electrode into the brain of a person with locked-in syndrome, scientists have demonstrated how to wirelessly transmit neural signals to a speech synthesizer. The "thought-to-speech" process takes about 50 milliseconds - the same amount of time for a non-paralyzed, neurologically intact person to speak their thoughts. The study marks the first successful demonstration of a permanently installed, wireless implant for real-time control of an external device. http://www.physorg.com/news180620740.html Medicine & Health Mon, 21 Dec 2009 12:26:19 EST news180620740 (PhysOrg.com) -- New connections begin to form between brain cells almost immediately as animals learn a new task, according to a study published this week in Nature. Led by researchers at the University of California, Santa Cruz, the study involved detailed observations of the rewiring processes that take place in the brain during motor learning. http://www.physorg.com/news178725126.html Medicine & Health Sun, 29 Nov 2009 13:52:39 EST news178725126 A Swiss research team has found that using an animal's own brain cells (autologous transplant) to replace degenerated neurons in select brain areas of donor primates with simulated but asymptomatic Parkinson's disease and previously in a motor cortex lesion model, provides a degree of brain protection and may be useful in repairing brain lesions and restoring function. http://www.physorg.com/news176014548.html Medicine & Health Thu, 29 Oct 2009 05:56:51 EST news176014548 (PhysOrg.com) -- For over a century, scientists have been using electrical stimulation to explore and treat the human brain. The technique has helped identify regions responsible for specific neural functions -- for instance, the motor cortex and pleasure center -- and has been used to treat a variety of conditions from Parkinson's disease to depression. Yet no one has been able to see what actually happens at the cellular level when the brain is electrically prodded. http://www.physorg.com/news170511294.html Medicine & Health Wed, 26 Aug 2009 13:16:00 EST news170511294 Although there is no doubt that hypnosis can impact the mind and behavior, the underlying brain mechanisms are not well understood. Now, new research provides fascinating insight into the specific neural effect of the power of suggestion. The study, published by Cell Press in the June 25 issue of the journal Neuron, uncovers the influence of hypnotic paralysis on brain networks involved in internal representations and self imagery. http://www.physorg.com/news165065163.html Medicine & Health Wed, 24 Jun 2009 12:40:03 EST news165065163 After a review of 284 cases, specialists at the Brain Tumor Center at the University of Cincinnati (UC) Neuroscience Institute have concluded that performing a stereotactic needle biopsy in an area of the brain associated with language or other important functions carries no greater risk than a similar biopsy in a less critical area of the brain. http://www.physorg.com/news163268266.html Medicine & Health Wed, 03 Jun 2009 17:18:27 EST news163268266 (PhysOrg.com) -- When one thinks of Einstein, it is natural to assume that obviously his brain differed from that of the average person. And, ever since Thomas Harvey, a pathologist in Princeton, removed Einstein's brain upon his 1955 death and documented it, scientists have been studying it. Currently, Einstein's brain is in 240 pieces, mounted on slides. However, measurements and photographs were taken of the brain prior to its dis-assembly, and these photos are pored over every few years by those wishing to unravel the secrets of the brain belonging to one of the geniuses of the 20th Century. http://www.physorg.com/news159536686.html Medicine & Health Tue, 21 Apr 2009 12:45:26 EST news159536686 A new area of the cerebral cortex has evolved to enable man and higher primates to pick up small objects and deftly use tools, according to neuroscientists at the University of Pittsburgh School of Medicine and Pittsburgh's Veterans Affairs Medical Center. http://www.physorg.com/news151002730.html Medicine & Health Mon, 12 Jan 2009 17:12:10 EST news151002730 Researchers in a study funded by the National Institutes of Health have demonstrated for the first time that a direct artificial connection from the brain to muscles can restore voluntary movement in monkeys whose arms have been temporarily anesthetized. The results may have promising implications for the quarter of a million Americans affected by spinal cord injuries and thousands of others with paralyzing neurological diseases, although clinical applications are years away. http://www.physorg.com/news143294842.html Medicine & Health Wed, 15 Oct 2008 13:07:22 EST news143294842
