Playing Tetris Boosts Brain Power

Researchers unsure whether it's pre-existing or games change brains

(NEWSER) - This is your brain on videogames: The brains of hardcore gamers are wired differently than those who rarely play video games, according to a new study. Researchers who scanned the brains of more than 150 14-year-olds found that the brain's "reward hub"—which plays a role in addiction—was bigger in frequent gamers, as it is in gambling addicts, the Los Angeles Times reports. The researchers couldn't determine whether gaming changed the brain, or whether having a certain brain structure made people likelier to enjoy gaming. 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.

Allen Institute maps gene activity in body's most complex organ

(NEWSER) - Researchers probing the staggering complexities of the human brain now have a map to help them find their way around. Scientists have unveiled a computerized "atlas of the brain," which combines several imaging techniques to map features including nerve structure and gene activity. The project, funded by Microsoft co-founder Paul Allen, offers researchers a tool to understand how genes work in the brain and to potentially find new treatment for disorders including autism and depression, reports the Wall Street Journal.
