Brain stimulation might help some functions and hurt others Electrically stimulating the brain may improve memory, but impede with a person’s ability to react without thinking. The approach has previously been shown to enhance various brain functions, including working memory and attention, and is being used to help stroke patients regain lost language and motor skills (see “Repairing the Stroke-Damaged Brain”). But until […]

Computer modeling may help soldiers, athletes, avoid concussions Johns Hopkins engineers have developed a powerful new computer-based process that helps identify the dangerous conditions that lead to concussion-related brain injuries. Professor K.T. Ramesh led a team that used a technique called diffusion tensor imaging, together with a computer model of the head, to identify injured axons, which are tiny but important fibers that […]

Radiation in space might harm the brains of astronauts “This study shows for the first time that exposure to radiation levels equivalent to a mission to Mars could produce cognitive problems and speed up changes in the brain that are associated with Alzheimer’s disease,” study author Kerry O’Banion, a neuroscientist at the University of Rochester Medical Center, said in a statement.

Brain technology market to exceed $1B by end of 2012 The market for brain health technology will surpass $1 billion by the end of 2012, and is set to grow at a brisk thereafter, to between $4 and $10 billion by 2020. Technologies in demand include computerized Web-based and mobile cognitive assessments, cognitive training and cognitive behavioral therapies, and biometrics-based monitoring and brain training […]

SPAUN brain model created inside a computer The Semantic Pointer Architecture Unified Network (Spaun) is a computer model of the human brain built by Professor Chris Eliasmith and colleagues of the University of Waterloo in Canada. It comprises around two and a half million virtual neurons organized into functional groups rather like real neurons in regions of the human brain associated […]
