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 »
