Brain can be made to self-repair

June 28, 2006

Triggering stem-cell growth could help the brain recover after a stroke.

Brain calisthenics for abstract ideas

June 6, 2011

Recent research has found that true experts have something at least as valuable as a mastery of the rules: gut instinct, an instantaneous grasp of the type of problem they’re up against. Like the ballplayer who can “read” pitches early, or the chess master who “sees” the best move, they’ve developed a great eye.

Now, a small group of cognitive scientists is arguing that schools and students could take… read more

Brain Boosters

June 28, 2007

A Technology Review reporter enters the new world of neuroenhancers by having his brain zapped with electricity and dosed with chemicals.

Brain boost drugs ‘growing trend’

October 15, 2008

Up to a fifth of adults, including college students and shift workers, may be using cognitive enhancers, a poll of 1,400 by Nature journal suggests.

Brain blanket boosts mind control

February 18, 2008

Researchers at Albany Medical College, Washington University, the University of Washington, the University of Wisconsin have developed a more effective brain-control interface device, using a sheet of closely spaced electrodes placed over the brain.

In recent experiments, five patients learned to control a computer cursor in two dimensions on a computer screen using their brain signals in less than 30 minutes, a performance similar to those achieved using electrodes… read more

Brain ‘avalanches’ may help store memories

January 27, 2005

Recent studies suggest that avalanches in your brain could actually help you to store memories.

Slices of rat brain tissue placed on a microelectrode array have shown that the brain cells activate each other in cascades called “neuronal avalanches.” New computer models by Indiana University biophysicist John Beggs now suggest that these brain avalanches may be optimal for information storage. If so, certain neurochemical treatments might someday improve life… read more

Brain artery model simulates cerebral blood vessel function for doctor training

April 25, 2012

The Cybram 001 Cybernetic Brain Artery Model, which simulates cerebral blood vessel functioning to allow doctors to develop brain-operation skills, has been developed by researchers at Fuyo Corporation and the Saitama Medical University International Medical Center in Japan.

The life-size plastic body contains a blood vessel system that runs from the groin to the cerebral artery, and a circulation pump controlled by information from a blood-pressure sensor to… read more

Brain activity provides novel biometric key

January 17, 2007

An electronic security system that identifies people by monitoring the unique pattern of electrical activity within their brain is being tested by scientists at the Centre for Research and Technology Hellas, in Greece.

The authentication system requires a user to have EEG measurements taken beforehand. The result of each authentication test is compared with the user’s pre-recorded measurements, using signal-processing algorithms.

Brain activity patterns preserve traces of previous cognitive activity

June 26, 2013

Weizmann Institute scientists discover that spontaneously emerging brain activity patterns preserve traces of previous cognitive activity.

What if experts could dig into the brain, like archaeologists, and uncover the history of past experiences? This ability might reveal what makes each of us a unique individual, and it could enable the objective diagnosis of a wide range of neuropsychological diseases.

New research at the Weizmann Institute hints… read more

Brain Activity Map Project is futile, say some scientists, others enthused

Complete human brain generates about 300,000 petabytes of data each year
February 28, 2013

In setting the nation on a course to map the active human brain, President Obama may have picked a challenge even more daunting than ending the war in Afghanistan or finding common ground with his Republican opponents, The New York Times reports.

Many neuroscientists are skeptical that a multiyear, multibillion dollar effort to unlock the brain’s mysteries will succeed.“I believe the scientific paradigm… read more

Brain abnormalities associated with casual marijuana use

April 17, 2014

Young adults who used marijuana only recreationally showed significant abnormalities in two key brain regions that are important in emotion and motivation, scientists report.

The study was a collaboration between Northwestern Medicine and Massachusetts General Hospital/Harvard Medical School.

This is the first study to show casual use of marijuana is related to major brain changes. It showed the degree of brain abnormalities in these regions is directly related… read more

Braille-like texting app speeds up typing on smartphones

February 21, 2012

Braille Touch

Ever need to text a note under the table during a meeting or during class without anyone knowing it?

Georgia Tech researchers have a solution: a free open-source iPhone app called BrailleTouch.

No, it’s not a solution for texting while driving.

“Research has shown that chorded, or gesture-based, texting is a viable solution for eyes-free written communication in the future,” says Mario Romero, Postdoctoral Fellow… read more

BPA, Chemical Used To Make Plastics, Found To Leach From Polycarbonate Drinking Bottles Into Humans

May 25, 2009

Study participants who drank for a week from polycarbonate bottles — the popular, hard-plastic drinking bottles and baby bottles — showed a two-thirds increase in their urine of the chemical bisphenol A (BPA), Harvard School of Public Health researchers have found.

Heating has been shown to increase the leaching of BPA from polycarbonate, so BPA levels might have been higher had participants drunk hot liquids from the bottles.… read more

Boyden to share prestigious brain prize

brain_prize_2013

Ed Boyden, a faculty member in the MIT Media Lab and the McGovern Institute for Brain Research, was named a recipient of the 2013 Grete Lundbeck European Brain Research Prize. The 1 million Euro prize is awarded for the development of optogenetics, a technology that makesread more

Boxer bares all

December 8, 2005

Researchers have published the full genetic code of a dog. It should make it easier to find the causes of genetic diseases, such as cancer, that affect both dogs and people.

The scientists involved in the effort, whose research appears in Nature on December 8, say the genome has already helped them to pinpoint a group of DNA sequences that do not code for specific genes, but are extremely… read more
