For decades it's been recognized that Alzheimer's patients can still remember and sing songs long after they've stopped recognizing names and faces. Now it's thought that...

New Brain Cells Bump Old Memories

Study finds new neurons clear out short-term memory

(Newser) - The birth of new brain cells bumps old memories into long-term storage, according to new research which upends earlier theories. Researchers working with rodents found that the creation of new neurons destabilized existing connections in the hippocampus instead of strengthening them as they had expected, effectively "clearing the inbox"...

Bad Driving Is in the Genes

Study says 30% can't help being lousy on the roads

(Newser) - Certain people—perhaps up to 30% of the population—may be fated by their genetic makeup to be bad drivers, a new study suggests. Researchers tested a small group of people on a driving simulator and found that subjects with a particular gene variant weren't so hot at keeping up...

Multitasking Causes Serious Brain Drain

Constant switching of focus is inefficient, can lead to trouble

(Newser) - Multitasking isn’t helping you do anything faster, and constant exposure to multiple electronic media makes people really bad at—multitasking. “When you’re pushing yourself to perform two or more tasks, especially complicated tasks, it’s not beneficial,” a researcher tells the Boston Globe . “It’s...

Your Brain Has a Neuron Just for Tom Cruise

...and another for every celeb you recognize, study finds

(Newser) - You have a neuron in your brain devoted entirely to recognizing Tom Cruise. Another specializes in Barack Obama, yet another LeBron James, and, yes, Jon and Kate are taking up two. By studying a decade worth of brain activity, researchers have discovered a series of cells that act like celebrity...

CIA Interrogations Caused Brain Damage: Scientist

Harsh techniques damaged subject's facility for recall

(Newser) - The CIA's harsh interrogations are likely to have damaged the brains of terrorist suspects, diminishing their ability to recall and provide the detailed information the spy agency sought, according to a new scientific paper. The paper scrutinizes the techniques used by the CIA under the Bush administration through the lens...

NFL Stars Donate Brains to Science

After death, players' brains will be used to help research into concussion injuries

(Newser) - Three NFL players have agreed to donate their brains after they die to help scientists better understand sports brain injuries, HealthDay reports. Matt Birk of the Baltimore Ravens, Lofa Tatupu of the Seattle Seahawks and the Arizona Cardinals' Sean Morey are the first active NFL players to join the brain...

Blueberry Smoothies Boost Brain Power

'Super food' can increase powers of concentration, ward off dementia

(Newser) - A blueberry smoothie in the morning is good for your brain in the afternoon—and in the long run, according to new research. Scientists at a British university found that one blueberry smoothie increased powers of concentration by as much as 20% in a single day. Consumption of blueberries can...

Reckless Teens Have More Mature Brains

Study links risky behavior to a better crop of white matter

(Newser) - Conventional wisdom says that teens who experiment with drugs, sex, and other risky behaviors do so because their brains—specifically the frontal-lobe areas responsible for decision making—are immature. But a new study turns that notion upside down, suggesting that risky teens have more mature brains than teens who play...

Playing Tetris Boosts Brain Power

Study claims game has building blocks for better grey matter

(Newser) - Playing Tetris leaves people's brains better-equipped to deal with more than just an onslaught of falling blocks, according to a new study. Researchers—funded by the video game's makers—took brain scans of adolescent girls before and after three months of daily Tetris playing and found that some parts of...

Scientist Seeks Help for the Hopelessly Lost

Brain disorder causes people to get lost even in their own homes

(Newser) - A Canadian neuroscientist has discovered a brain disorder that causes sufferers to spend their lives hopelessly lost even in their own neighborhoods, reports the Canadian Press. People with developmental topographical disorientation utterly lack the ability to form mental maps and orient themselves, leaving them with no idea how to navigate...

High Cholesterol in 40s Tied to Dementia Later

Lowering it won't necessarily help, studies suggest

(Newser) - High cholesterol in middle age may increase a person’s future risk of Alzheimer’s disease, NPR reports. “Our study shows that even moderately high cholesterol levels in your 40s puts people at greater risk for Alzheimer's disease and vascular dementia in later life,” says one researcher, who...

Cloudiness reduces cognitive agility in depressed people, researchers found

(Newser) - Does a cloudy day leave you groggy and unable to focus? If so, a study suggests you’re not alone: Cloudy days, regardless of season, can have an effect on cognitive function, MSNBC reports. Researchers cross-referencing the results of cognitive tests from 16,800 Americans with data on daily sunshine...

Artificial Brain Could Be Just 10 Years Away

(Newser) - A functional artificial brain could be built within the next decade, leading scientist and brain-builder Henry Markram told a tech conference. Markram, who leads a project seeking to reverse engineer the mammalian brain from lab data, says his team has already duplicated parts of the rat brain, the BBC reports....

Fish Oil Reverses Tide on Memory Loss

(Newser) - Regular doses of Omega 3, found in fish oil, can help reduce memory loss, reports the Telegraph. Healthy 70-year-old subjects taking capsules containing 900 mg of the fatty acid docosahexaenoic slashed errors on a test that measured learning and memory, according to researchers. The improvement, exhibited over a six-month period,...

Video Games May Stave Off Mental Decline

(Newser) - Shelling goblins and building medieval empires may be perfect ways to stave off cognitive decline, Anita Hamilton writes in Time. Research already shows that challenging tasks can keep brains sharp in old age, but now multi-million-dollar studies are getting the elderly to play video games—not puzzle or math games,...

Real 'Thinking Cap' May Not Be So Far Off

Magnetic pulse boosts learning, study shows; headgear next?

(Newser) - A magnetic pulse directed at a certain area of the brain may enhance learning and memory, the Telegraph reports. Canadian researchers subjected volunteers to a test that required they track a dot moving on a computer screen with a joystick, and volunteers who received stimulation fared much better.

Want to Bum a Smoke? Whisper in Their Right Ear

(Newser) - People prefer to listen with their right ears and are more giving when addressed from that side, LiveScience reports. An Italian study conducted in nightclubs shows that almost three-quarters of people observed listen with their right ear. Moreover, the researchers cadged significantly more cigarettes when they approached clubgoers on the...

Insurer Sees Games as Boost for Old Brains

'Mental fitness' software improves reaction time, peripheral vision

(Newser) - An experiment by Allstate Insurance and a San Francisco software startup that aims to use computer games to improve the mental health of all ages is getting good reviews, the Chronicle reports, including from one local who says improved reaction time and peripheral vision saved him from an accident. “...

'Rogue' Protein Spread Key to Alzheimer's

Discovery casts light on tangles found in brains of disease sufferers

(Newser) - A protein linked to Alzheimer’s can run amok in the brain, affecting healthy tissue, scientists have found. All nerve cells contain the tau protein, but a “rogue form” can lead to protein clumps in cells, called neurofibrillary tangles, that are believed to play a major role in Alzheimer’...
