By carefully analyzing brain activity, scientists can tell what number a person has just seen, research now reveals. They can similarly tell how many dots a person was presented with. Past investigations had uncovered brain cells in monkeys that were linked with numbers. Although scientists had found brain regions linked with numerical tasks in humans - the frontal and parietal lobes, to be exact - until now patterns of brain activity linked with specific numbers had proven elusive. Scientists had 10 volunteers watch either numerals or dots on a screen while a part of their brain known as the intraparietal...

Scientists at Georgia State University have uncovered the mechanisms of how pain in infancy alters how the brain processes pain in adulthood. Research is now indicating that infants who spent time in the neonatal intensive care unit (NICU) show altered pain sensitivity in adolescence. These results have profound implications and highlight the need for pre-emptive and post-operative pain medicine for newborn infants. The study, published online in the journal Frontiers in Behavioral Neuroscience, sheds light on how the mechanisms of pain are altered after infant injury in a region of the brain called the periaqueductal gray, which is involved in...

The standard explanation for what causes Alzheimer's is known as the amyloid hypothesis, which posits that the disease results from of an accumulation of the peptide amyloid beta, the toxic protein fragments that deposit in the brain and become the sticky plaques that have defined Alzheimer's for more than 100 years. Billions of dollars are spent yearly targeting this toxic peptide — but what if this is the wrong target? What if the disease begins much earlier, fueled by a natural process? Reporting in the current edition of the journal Neurobiology of Aging, UCLA professor of psychiatry George Bartzokis argues...

WASHINGTON (AP) - More than 35 million people around the world are living with Alzheimer's disease or other types of dementia, says the most in-depth attempt yet to assess the brain-destroying illness—and it's an ominous forecast as the population grays. The new count is about 10 percent higher than what scientists had predicted just a few years ago, because earlier research underestimated Alzheimer's growing impact in developing countries. Barring a medical breakthrough, the World Alzheimer Report projects dementia will nearly double every 20 years. By 2050, it will affect a staggering 115.4 million people, the report concludes.

Miami, FL (AHN) - Babies fed formula supplemented with an essential fatty acid found in breast milk have higher cognitive skills than babies fed formula alone, according to a new study. Previous research already showed the cognitive benefits of breastfeeding, but University of Texas researchers and scientists with the Retina Foundation of the Southwest said they have discovered that the fatty acid docosahexaenoic acid, or DHA, could be the reason. The scientists studied 229 infants receiving either formula or a combination of formula and DHA. The babies were given the different formulas either shortly after they were born, after six...

Unlike any man-made computer, the brain is made of living cells that must constantly change as we acquire new skills and information. It appears that the physical architecture of the brain itself changes in response to our experiences. Such a marvelous design makes it possible for us to grow and adapt to our changing environment...

Finding could offer insight into autism and other disorders Related Links: Dr. Ralph Adolphs Pasadena, Calif.—In a finding that sheds new light on the neural mechanisms involved in social behavior, neuroscientists at the California Institute of Technology (Caltech) have pinpointed the brain structure responsible for our sense of personal space.The discovery, described in the August 30 issue of the journal Nature Neuroscience, could offer insight into autism and other disorders where social distance is an issue.The structure, the amygdala—a pair of almond-shaped regions located in the medial temporal lobes—was previously known to process strong negative emotions, such as anger and...

A new study finds obese people have 8 percent less brain tissue than normal-weight individuals. Their brains look 16 years older than the brains of lean individuals, researchers said today. Those classified as overweight have 4 percent less brain tissue and their brains appear to have aged prematurely by 8 years. The results, based on brain scans of 94 people in their 70s, represent "severe brain degeneration," said Paul Thompson, senior author of the study and a UCLA professor of neurology. "That's a big loss of tissue and it depletes your cognitive reserves, putting you at much greater risk of...

Seeking. You can't stop doing it. Sometimes it feels as if the basic drives for food, sex, and sleep have been overridden by a new need for endless nuggets of electronic information. We are so insatiably curious that we gather data even if it gets us in trouble. Google searches are becoming a cause of mistrials as jurors, after hearing testimony, ignore judges' instructions and go look up facts for themselves. We search for information we don't even care about. Nina Shen Rastogi confessed in Double X, "My boyfriend has threatened to break up with me if I keep whipping...

Michael Jackson's brain has been returned to his family in a move that could finally see him buried. The organ was removed from the 50-year-old singer's body following his death on June 25. Pathologists then carried out tests in an attempt to discover what killed him.

Scientists have long searched for a biological basis for psychopathy, a behavioral disorder attributed to chronic immorality. While previous studies have found no clear evidence, Professor Declan Murphy of the Institute of Psychiatry at King's College London believes he has found an area of the brain that is decidedly different in a psychopath as compared to a normal person. It is unsurprising that much of the research to date has focused on the amygdale (the part of the brain involved with emotions and aggression) and the orbitofrontal cortex (which deals in decision making). However, an unstudied area is the uncinate...

July 28, 2009 (LifeSiteNews.com) - Scientists are stunned to discover that a ten-year-old German girl's brain has rewired itself to allow her to see out of one eye as though she has two, even though half of her brain tissue was entirely missing from birth. In a report published this week in the online version of the journal of the Proceedings of the National Academy of Science, Lars Muckli, a neuroscientist at the University of Glasgow, Scotland, said, "Despite lacking one hemisphere, she's capable of living a normal life."The girl, called AH in the study, was born with only one...

When we daydream about the future, we tend to focus on the fabulous belongings we're going to have. Jet packs, flying cars, weapons to kill aliens, cell phones that make today's sleek models look clunky -- you name it, we're going to have it. We don't tend to focus, however, on who we'll be in the future. Most of us probably picture ourselves exactly the same, though maybe thinner, as surely we'll all have robot personal trainers by then. While we see the world's technology evolving to meet our needs, we may not think about how we ourselves might be...

The parents of Sam Esquibel know him only as a miracle baby. The Colorado Springs infant survived surgery to remove what was believed to be a tumor when he was just 3 days old. "The doctors said to us, 'This one is for the books,' " mom Tiffnie Esquibel said. Inside the microscopic tumor was what looked like the formations of two feet, a hand and thigh. "To find a perfectly formed structure (like this) is extremely unique, unusual, borderline unheard of," said Dr. Paul Grabb, the veteran pediatric neurosurgeon who performed the operation on Sam at Colorado Springs' Memorial...

Almost four decades ago, the 26th Amendment lowered the US voting age to 18.  At the time, most neurologists believed that the human brain was fully developed by about age 12, so allowing Americans to vote at 18 seemed like a safe move. But parents of teenagers knew that was nonsense, and new research is confirming those parental observations.  Since the voting age was lowered in 1971, scientific advancements such as magnetic resonance imaging (MRI) allowed researchers to get detailed three-dimensional images of developing brains. Although human brains typically reach their adult size by age 12, they are far from...

July 16, 2009 (LifeSiteNews.com) - 30-week-old babies in the womb already have short-term memory capabilities, a new study from the Netherlands, published in the July/August 2009 issue of the journal Child Development, has found.Researchers at Maastricht University Medical Centre and the University Medical Centre St. Radboud examined 93 healthy pregnant Dutch women and their unborn children, measuring changes in how the child responds to repeated stimulation. The children were tested at 30, 32, 34, and 36 weeks, and again at 38 weeks gestation.  The study showed that the unborn children would initially respond to a "vibroacoustic" stimulus. The stimulus would...
