Mind-Reading Edges Closer to Reality

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 were then able to correctly guess which word volunteers had chosen from a list and were thinking of, the BBC reports. More»

Doctors pinpoint the so-called 'nocebo' effect

(NEWSER) - Worried that it's unhealthy to be glued to the Internet, surfing through stories? That anxiety alone could cause health problems—and doctors are now uncovering the neurological roots of this so-called "nocebo" effect, according to an award-winning essay by Penny Sarchet in the Guardian . The opposite of the "placebo" effect, the "nocebo" effect occurs when people believe that an illness or side-effect is real. Turns out it's all in the mind, and scientists can pinpoint it. More»

Monkeys keep their gray matter throughout their lives

(NEWSER) - Next time you start to feel mentally superior to a chimp, think again. It turns out that while human brains shrink as they age, chimpanzee brains do not, a new George Washington University study has discovered. The findings upend the conventional wisdom that all primates saw their brains shrink over time, the Wall Street Journal explains—in fact, the researchers now suspect that only humans decline in this way.

No, we don't just use 10% of the thing

(NEWSER) - The brain is much mythologized in mainstream culture—so much so that many believed “facts” are actually fiction, reports the Smithsonian:

1. We use just 10% of our brains. Nope, brains scans show that even basic tasks use a large portion of the brain—and even a small brain injury can have big repercussions.
2. We lose brain power after 40. It does get harder to learn languages or memorize random words—but older people have bigger vocabularies, are better at judging character, and test better on social matters, like conflict resolution.

Study shows parts of the brain can shut off

(NEWSER) - Ever feel so bushwhacked that you tell someone you’re “half asleep”? Well, it turns out you probably were. Researchers have found that parts of your brain actually do turn off when you’re fatigued—sometimes even before you’re consciously aware that you’re tired, according to a new study. These slumbering neurons can cause small errors or brain farts, like putting the milk in the cupboard and the cereal in the fridge, the Telegraph reports. More»
