New technology bypasses spinal cord and delivers electrical signals from brain directly to muscles A new Northwestern Medicine brain-machine technology delivers messages from the brain directly to the muscles -- bypassing the spinal cord -- to enable voluntary and complex movement of a paralyzed hand. The device could eventually be tested on, and perhaps aid, paralyzed patients. "We are eavesdropping on the natural electrical signals from the brain that tell the arm and hand how to...

Patients with 'pseudo-seizures' often misdiagnosed Based on their clinical experience and observations, a team of Johns Hopkins physicians and psychologists say that more than one-third of the patients admitted to The Johns Hopkins Hospital's inpatient epilepsy monitoring unit for treatment of intractable seizures have been discovered to have stress-triggered symptoms rather than a true seizure disorder. These patients — returning war veterans, mothers in child-custody battles and...

CHARLOTTE, N.C., April 9, 2012 /PRNewswire/ -- The double-blind study, conducted at the Wake Forest Baptist Hospital Research Center, applied Brain State Technologies® Brainwave Optimization techniques to several groups of participants. After the initial study, Lee Gerdes, the founder of Brain State, requested that researchers run the experiment again on the placebo group, to ensure that all the study participants were able to experience the benefits of the sleep-improving...

Belkasoft develops a software toolkit, adapting commercially available brain activity analysis hardware for solving criminal cases. The new product, Belkasoft Mind Analyzer, enables the acquisition of human faces by capturing fMRI data generated by human brain cells. A dedicated facial recognition engine allows reliable identification of acquired faces against a pre-filled database, while the optional Identikit module allows building convincing facial composites. The tool runs in...

Scientists from Tuebingen discovered new functions of brain regions that are responsible for seeing movement When observing a fly buzzing around the room, we should have the impression that it is not the fly, but rather the space that lies behind it that is moving. After all, the fly is always fixed in our central point of view. But how does the brain convey the impression of a fly in motion in a motionless field? With the help of functional magnetic resonance imaging (fMRI) scientists...

Infants' faces evoke species-specific patterns of brain activity in adults Distinct patterns of activity—which may indicate a predisposition to care for infants-- appear in the brains of adults who view an image of an infant face—even when the child is not theirs, according to a study by researchers at the National Institutes of Health and in Germany, Italy, and Japan. Seeing images of infant faces appeared to activate in the adult's brains circuits that reflect preparation for...

PITTSBURGH, March 6, 2012 /PRNewswire/ -- New research from Carnegie Mellon University's Marcel Just provides an explanation for some of autism's mysteries -- from social and communication disorders to restricted interests -- and gives scientists clear targets for developing intervention and treatment therapies. (Logo: http://photos.prnewswire.com/prnh/20020422/CMULOGO ) Autism has long been a scientific enigma, mainly due to its diverse and seemingly unrelated symptoms until...

SCHIEDLBERG, Austria, March 5, 2012 /PRNewswire/ -- In 2009, g.tec introduced the intendiX-SPELLER, the first commercially available brain-computer-interface (BCI) system for home use. Soon, g.tec will release the intendiX-SOCI (screen-overlay-control-interface), allowing people to control PC-applications such as computer games with a brain-computer interface. Although this system will not be available until later in 2012, g.tec will host the first public demonstration...

Finnish researchers break ground in neonatal brain research In the past few years, researchers at the University of Helsinki have made several breakthroughs in discovering how the brain of preterm babies work, in developing treatments to protect the brain, and in developing research methods suitable for hospital use. Each year, the brains of hundreds of Finnish children, and therefore their future lives, are at risk due to premature birth or intrapartum asphyxia. The brain is a...

Findings suggest simple methods to detect consciousness may bypass patients who can communicate, but not in recognizable ways By employing complex machine learning techniques to decipher repeated advanced brain scans, researchers at New York‑Presbyterian/Weill Cornell were able to provide evidence that a patient with a severe brain injury could, in her way, communicate accurately. Their study, published in the Feb. 13 issue of the Archives of Neurology, demonstrates how difficult it...
