Even in Geniuses, Hard Work Trumps IQ

Brain activity research could be applied to sleeping subjects

(NEWSER) - Sounds like something out of a movie, but it's real: Someday, scientists may be able to "record" your dreams. Research published in the journal Nature explains that it is already possible to record higher-level brain activity, and the same methods could be applied to dreams—though there is still a long way to go, the BBC reports. Scientists found that certain neurons are associated with objects or concepts in each of our brains—when you think about "Marilyn Monroe," a specific neuron lights up. More»

Work keeps brain alert, cells connected

(NEWSER) - It may be a bitter pill to swallow, but delaying retirement is one way to stave off Alzheimer's, a new study has found. Each extra year of work amounted to a six-week delay in the condition's development among patients studied. Alzheimer's is caused by brain cell loss, and the mental stimulation of work may help keep those cells connected, BBC reports. More»

(NEWSER) - If you ended your holiday visit home with frayed nerves, blame your brain, not your brother's snoring, Discovery reports. Family members prompt activity in a different part of the brain from friends and strangers, a new study shows. Researchers used MRIs to look at subjects' brains while they viewed photos of biological relatives and people who liked like the subjects, as well as photos of friends and strangers who weren't lookalikes.

New computer can determine what you're looking at

(NEWSER) - Mind-reading has taken a step toward possibility with a new computer that can decode brain activity to determine what a person is looking at with up to 90% accuracy, the Independent reports. With improvements, the technology could be able to reconstruct any image a person could conjure up—and someday, their very thoughts and dreams, said the lead researcher of the experiments detailed in the journal Nature.

Evolutionary adaptation keeps the nervous system's motherboard cool

(NEWSER) - Yawning may be less a response to boredom than a natural mechanism for cooling off overheated brains, new research says. The human brain operates optimally when cool, much like a computer, and conditions like fatigue actually cause the organ to heat up, ABC News reports. A quick gulp of air can offer relief to sweltering skulls. More»
