New neurons may explain why adults can’t remember being infants Unlike the proverbial elephants, babies always forget. Infants’ memories may be wiped clean by the genesis of new brain cells, a study in rodents suggests. The findings offer an explanation for why people can’t recall memories from early childhood, a century-old mystery. The study’s authors “make a very interesting and compelling case,” says neuroscientist and psychiatrist Thomas Insel, director of the National Institute for Mental Health in Bethesda, Md. “It’s just truly fascinating,” he says. “Nobody has actually looked at this very carefully before.” More than 100 years ago, Sigmund...

Wednesday, 'Wheel of Fortune' had a very inspirational contestant in Trent Girone. The 21-year-old Peoria, Ariz., resident is a self-described "Wheel of Fortune" fanatic, but more important, he's the first special needs contestant ever to compete on the show.Girone has had nine brain surgeries and has both Asperger's and Tourette's syndromes, but that didn't stop him from taking early control of the wheel by successfully guessing the first puzzle, "a smashing success." Girone ultimately didn't win the game -- he hit the dreaded Bankrupt slot -- but he won viewer hearts from coast-to-coast.  WATCH:

Type 2 diabetes could cause the brain to age by up to two years every decade a person has the disease, researchers have claimed. It is the first time diabetes has been linked to a change in the size of the brain. The study also found that, contrary to common clinical belief, diabetes may not be directly associated with small vessel ischemic disease, where the brain does not receive enough oxygenated blood. 'We found that patients having more severe diabetes had less brain tissue, suggesting brain atrophy,' said lead author R. Nick Bryan, M.D., Ph.D., professor of radiology at the...

TRES RIOS, Costa Rica (AP) — On a warm spring day, Floribeth Mora was in her bed waiting to die from a seemingly inoperable brain aneurysm when her gaze fell upon a photograph of Pope John Paul II in a newspaper. "Stand up," Mora recalls the image of the pope saying to her. "Don't be afraid." Mora, her doctors and the Catholic Church say her aneurysm disappeared that day in a miracle that cleared the way for the late pope to be declared a saint on April 27 in a ceremony at the Vatican where Mora will be a guest...

Every day, the push toward national legalization of marijuana seems more and more inevitable. As more and more politicians and noted individuals come out in favor of legalizing or at least decriminalizing different amounts of pot, the mainstream acceptance of the recreational use of the drug seems like a bygone conclusion. But before we can talk about legalization, have we fully understood the health effects of marijuana?

...Researchers at Northwestern University have analyzed the relationship between casual use of marijuana and brain changes – and found that young adults who used cannabis just once or twice a week showed significant abnormalities in two important brain structures. The study’s findings, to be published Wednesday in the Journal of Neuroscience, are similar to those of past research linking chronic, long-term marijuana use with mental illness and changes in brain development. Dr. Hans Breiter, co-senior study author, said he was inspired to look at the effects of casual marijuana use after previous work in his lab found that heavy cannabis...

Sleep loss may be more serious than previously thought, causing a permanent loss of brain cells, research suggests. In mice, prolonged lack of sleep led to 25% of certain brain cells dying, according to a study in The Journal of Neuroscience. If the same is true in humans, it may be futile to try to catch up on missed sleep, say US scientists. They think it may one day be possible to develop a drug to protect the brain from the side-effects of lost sleep. …

Roger Bowley, a physics professor at the University of Nottingham, explains why holding a key fob next to your brain can help extend its signal. He also demonstrates the same effect using a bottle of water, which comes in handy when trying to unlock a car.

LifeNews has repeatedly chronicled cases of people who were prematurely declared dead or said to be in supposedly persistent vegetative states who ultimately recovered. Now comes the story of Lexi Hansen, a BYU student who suffered critical head injuries last week after being hit by a car. Hansen, 18, was alert and breathing on her own Tuesday, though she was still listed in critical but stable condition. She even tried to get out of her hospital bed. While she has a long road to recovery ahead, her family believes they have witnessed a miracle. lexihansen“When they brought her in, the...

As scanning becomes more sophisticated researchers are finding that there is actually a difference in the way development takes place in the brains of men and women starting in the teenage years.

Older women with higher levels of omega-3 fatty acids in their blood had slightly less brain shrinkage than women with low fatty acid levels in a new study. The results may suggest that omega-3s protect the brain from the loss of volume that happens with normal aging and is seen more severely in people with dementia, the researchers say.

Research shows people with higher levels of the omega-3 fatty acids found in fish oil may also have larger brain volumes in old age This would be the equivalent to preserving one or two years of brain health. Eating more fish could give you a bigger brain - and greater protection against diseases such as Alzheimer’s, claim researchers. They found people with higher levels of the omega-3 fatty acids found in fish oil may also have larger brain volumes in old age. This would be the equivalent to preserving one to two years of brain health, says a new study...

The brains of older people only appear to slow down because they have so much information to compute, much like a full-up hard drive, scientists believe. Older people do not decline mentally with age, it just takes them longer to recall facts because they have more information in their brains, scientists believe. Much like a computer struggles as the hard drive gets full up, so to (sic) do humans take longer to access information, it has been suggested. Researchers say this slowing down it is not the same as cognitive decline. “The human brain works slower in old age,” said...

January 19, 2014, 10:10 am Obama: Danger of concussions in NFL ‘no longer a secret’ By Justin Sink President Obama said that he believed NFL players “know what they’re doing” and understood the impact that concussions could have on their long-term health in an interview with The New Yorker published on Sunday, adding that he would not let his son play pro football. “At this point, there’s a little bit of caveat emptor,” Obama said. “These guys, they know what they’re doing. They know what they’re buying into. It is no longer a secret. It’s sort of the feeling I...

A first-of-its kind study set to be released Monday finds that older adults who engaged in brain training drills retained measurable benefits up to 10 years later, suggesting that such interventions may help stave off impairments of aging that rob seniors of their independence. The latest trial found that nearly three-quarters of those who participated in reasoning exercises and information-processing drills still displayed those abilities a decade later.

Researchers in Baltimore, Maryland, carried out tests on 100 people Showed them a series of images which they had to remember Then gave some participants 200mg of caffeine - the same as a strong cup Those who took dose could remember pictures more clearly the next day Coffee doesn’t just perk you up – just one mug a day can give your memory a boost too, experts claimed yesterday. ‘We have always known caffeine has cognitive enhancing effects, but its particular effects on strengthening memories and making them resistant to forgetting has never been examined in detail in humans. We...

This was proven by a study by Grethe Jensen and co. (1993), who meticulously counted neurons in matched samples of non-alcoholics and alcoholics. What they found was that there was no real difference in the density or overall number of neurons between the two groups. In every group, those who drank moderately on a regular basis throughout their lives always had a diminished chance of becoming mentally impaired in their old age compared to those who didn't drink at all or almost never drank. Now for the negative (there's a lot when it comes to intemperate alcohol consumption, so I'll...

At least one in five patients declared brain dead and approved as organ donors by one organ donation organization, are in fact still alive and are being killed by the removal of vital organs, a lawsuit filed last week in Manhattan alleges. The suit outlines the ghoulish worst-case scenario, one that was widely dismissed as scaremongering in the early days of the development of organ transplant technology, but which is getting a second hearing amidst growing concerns that coercion and abuse are becoming increasingly common in the highly lucrative transplant business. Patrick McMahon, a nurse practitioner and Air Force combat...

In modern times there has been a tendency to downplay the differences between men and women, preferring to see whatever differences have historically existed as simply social constructs. This thinking was insisted upon by many as a kind of political correctness that must be held otherwise punishment and excoriation was sure to follow.Nevertheless, most people with common sense have always known that men and women are very different, and that these differences are not simply the result of social constructs or the way people were raised.Now scientists have made discoveries not only affirming that men and women are different, but...
