Scientists Able to ID 'Aware' Vegetative Patients

Cambridge study finds 'signs of hidden awareness' in unresponsive patients

(Newser) - A new study offers a potential way to identify comatose patients who might be "covertly aware." University of Cambridge researchers studied the brain waves of 32 coma patients—including "minimally conscious" patients who could, say, squeeze a finger on command; "vegetative" patients who were unmoving; and...

Messages Sent From Brain to Brain Over 5K Miles

First-of-its kind experiment relays 'hola' and 'ciao' from India to France

(Newser) - A team of neuroscientists tapped into brain-wave-reading gear, binary code, and the Internet to transmit thoughts from a subject in India to three human "receivers" in France—about 5,000 miles away, reports Popular Science . The four participants, ages 28-50, were hooked up to equipment that looked like it... More »

Clue to Near-Death Experiences Uncovered

Scientists find rats' brains go into overdrive after cardiac arrest

(Newser) - A fascinating (and somewhat macabre) new study may explain the so-called "near-death experiences" described by many people. Scientists studied the brains of nine rats as they were being euthanized and found that just after the rats' hearts stopped, their brains became more active than normal, NPR reports. This sort...

Scientists Try to 'Hack' Stephen Hawking's Mind

Stanford team wants to get around his motor neurone disease

(Newser) - Imagine looking directly into Stephen Hawking's mind as he contemplates the universe. That's exactly what scientists are attempting with a tool called the iBrain, which detects electrical brain waves and conveys them to a computer, the Telegraph reports. "We'd like to find a way to bypass... More »

Scientists Get Step Closer to Decoding Our Thoughts

Computers track brain activity as words are heard

(Newser) - Scientists have taken a big step toward being able to decode our thoughts. Researchers working with brain surgery patients taught computers to decipher the brain activity that takes place when words are heard. The brain, they found, breaks sounds down into their consistent acoustic frequencies. Using that computer model, they... More »

Awareness Detected in 'Vegetative' Patients

Study results could provide new hope for patients thought to be unresponsive

(Newser) - A new study could have a life-changing impact on patients thought to be in a “vegetative” state: Three such patients displayed signs of full consciousness in a simple test. “It sure looks as if there’s not just a little bit of consciousness but a lot” in these... More »

Brain Waves Translated Into Words

Study proves electrodes can capture speech signals

(Newser) - University of Utah researchers have translated brain waves into words using microelectrodes planted over the brain's speech centers. They stress that although the technology is in its infancy—they could only distinguish the correct word from 10 possibilities half the time—the study proves that it can be done, and... More »

Man in Vegetative State 'Talks'

He communicates through brain waves linked to computer

(Newser) - A man in a deeply unconscious state for 5 years has been able to communicate with doctors using only his thoughts. In a study one Cornell neurologist called a "game changer" for the care of patients in a vegetative state, British and Belgian researchers used a brain scanner to... More »

Cell Phone Radiation May Stave Off Alzheimer's

Electromagnetic waves might boost memory

(Newser) - Researchers finally have some good news about the health effects of cell phones. The electromagnetic waves the phones emit may improve memory and prevent Alzheimer's disease, according to a recent study of mice exposed to radiation similar to electromagnetic waves from cell phones. The mice showed improved cognitive function and... More »

Toyota Rolls Out Mind-Controlled Wheelchair

Chair can translate thoughts into commands within milliseconds

(Newser) - Toyota has unveiled research on a mind-controlled wheelchair that can read its user's thoughts much faster and more accurately than any previous efforts, the Christian Science Monitor reports. The chair's interface reads brainwave activity and responds to imagined hand and foot movements within 125 milliseconds with up to 95% accuracy,... More »
