Machine-learning system finds differences in brain connectivityA computational physicist and a cognitive neuroscientist at Children's Hospital Boston have come up with the beginnings of a noninvasive test to evaluate an infant's autism risk. It combines the standard electroencephalogram (EEG), which records electrical activity in the brain, with machine-learning algorithms. In a pilot study, their system had 80 percent accuracy in distinguishing between 9-month-old infants known to be at high...
Mind over matterDaniel Moran has dedicated his career to developing the best brain-computer interface, or BCI, he possibly can. His motivation is simple but compelling. "My sophomore year in high school," Moran says, "a good friend and I were on the varsity baseball team. I broke my arm and was out for the season. I was feeling sorry for myself when he slide into home plate head first and broke his neck."So I knew what I wanted to do when I was 15 years old, and all my...
By Michael C. Purdy, Washington University in St. LouisLike listeners adjusting a high-tech radio, scientists at Washington University School of Medicine in St. Louis have tuned in to precise frequencies of brain activity to unleash new insights into how the brain works."Analysis of brain function normally focuses on where brain activity happens and when," says Eric C. Leuthardt, MD. "What we've found is that the wavelength of the activity provides a third major branch of understanding brain...
If you already know what you are about to see, you will recognise it faster The human brain works incredibly fast. However, visual impressions are so complex that their processing takes several hundred milliseconds before they enter our consciousness. Scientists at the Max Planck Institute for Brain Research in Frankfurt am Main have now shown that this delay may vary in length. When the brain possesses some prior information − that is, when it already knows what it is about to see...
Coordinated behavior occurs whether or not neurons are actually connected via synapsesThe brain"”awake and sleeping"”is awash in electrical activity, and not just from the individual pings of single neurons communicating with each other. In fact, the brain is enveloped in countless overlapping electric fields, generated by the neural circuits of scores of communicating neurons. The fields were once thought to be an "epiphenomenon, a 'bug' of sorts, occurring during neural...
ESA astronaut Paolo Nespoli, now working as a flight engineer on the International Space Station, is busy with a range of scientific experiments. The latest is peering inside his head to help understand how the human brain works.Our brains are changing all the time "“ nerves are rearranging themselves and the connections between the nerve cells are reforming as the brain memorizes new information, stores the old and continuously adapts to new situations.New experiences, learning,...
Imaging system could help reveal 'miscommunications' in autism, schizophreniaSome disorders of the brain are obvious "” the massive death of brain cells after a stroke, the explosion in the growth of cells that marks a tumor. Other disorders, such as autism, schizophrenia and mental retardation show no physical signs of damage and are believed to be caused by problems in how brain cells communicate with one another.To understand the root of the problem of these latter diseases, visualizing...
Brainwave experts unveil audio sessions for increasing happiness, focus, and creativity Beverly Hills, CA (PRWEB) January 10, 2011 It sounds like something from a science fiction movie. Just press a button "“ and quickly boost your happiness, get focused, or fall to sleep. But thanks to one British company, this hi-tech dream is turning into a reality. Today marks the official launch of the "Brain Salon," an audio program that uses specialized sounds to influence your brainwaves, and...
Babies, even those too young to talk, can understand many of the words that adults are saying "“ and their brains process them in a grown-up way.Combining the cutting-edge technologies of MRI and MEG, scientists at the University of California, San Diego show that babies just over a year old process words they hear with the same brain structures as adults, and in the same amount of time. Moreover, the researchers found that babies were not merely processing the words as sounds, but were...
