    The journal Epilepsy and Behavior published the findings of the accidental discovery. The evidence was found when scientists were studying an epilepsy patient. They used electrodes deep within a patient's brain to try to determine where her seizures were coming from. ... The scientists stimulated an area of the brain called the claustrum, an area of the brain that had never been stimulated. Once stimulated, the woman, who was reading, stopped responding to all visual and audible cues, as if she were a robot that had been shut down. The team was able to recreate the scenario several times to...

    Certain areas of the brain associated with reward and response to gut feelings have shown links to trading behavior and success, according to research published Monday in the journal Proceedings of the National Academy of Sciences. The study shows that activity in one area of the brain actually tracks price bubbles—and that higher earners get signals from a different area that are associated with selling before a price bubble peaks.

    Is There a Brain Region Associated with a Belief in Social Justice? Some people believe that we could live in a just world where everybody gets what they deserve. Others believe that's impossible. Now, neuroscientists say they have evidence that the "just world hypothesis" is a cognitive bias that's connected with a specific part of the brain. This does not mean there is a "social justice center" in your brain. What neurologist Michael Schaefer and colleagues discovered is that there is a slightly different pattern of electrical impulses shooting through the brains of people who believe in a just world....

    Shocking the brain with mild electrical current was once a controversial treatment for the mentally ill. Now evidence is emerging that it could quicken learning and improve attention, and as Emma Young discovers, the US military is very interested in its potential. An unusual trial is underway at the Wright-Patterson Air Force Base, near Dayton, Ohio. An airman sits at a monitor in a laboratory, wired up with electrodes, his jacket slung over the back of his chair. Plane-shaped icons keep entering his airspace. He has to decide whether each incoming plane is a friend or a foe. If it’s...

    Pedophiles’ brains are “abnormally tuned” to find young children attractive, according to a new study published this week. The research, led by Jorge Ponseti at Germany’s University of Kiel, means that it may be possible to diagnose pedophiles in the future before they are able to offend. The findings, published in scientific journal Biology Letters, discovered that pedophiles have the same neurological reaction to images of those they find attractive as those of people with ordinary sexual predilections, but that all the relevant cerebral areas become engaged when they see children, as opposed to fellow adults. The occipital areas, prefrontal...

    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...

    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...

    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...

The top brain comprises the entire parietal lobe and the top (and larger) portion of the frontal lobe. The bottom comprises the smaller remainder of the frontal lobe and all of the occipital and temporal lobes. Our theory's roots lie in a landmark report published in 1982 by Mortimer Mishkin and Leslie G. Ungerleider of the National Institute of Mental Health....

    The US team believe the "waste removal system" is one of the fundamental reasons for sleep. Their study, in the journal Science, showed brain cells shrink during sleep to open up the gaps between neurons and allow fluid to wash the brain clean. They also suggest that failing to clear away some toxic proteins may play a role in brain disorders. Their findings build on last year's discovery of the brain's own network of plumbing pipes - known as the glymphatic system - which carry waste material out of the brain.

    New guidance for psychologists will acknowledge that adolescence now effectively runs up until the age of 25 for the purposes of treating young people. So is this the new cut-off point for adulthood? "The idea that suddenly at 18 you're an adult just doesn't quite ring true," says child psychologist Laverne Antrobus, who works at London's Tavistock Clinic.

    It’s an inconvenient truth of aging: In our 30s and up, it gets increasingly harder for most of us to recall names, faces, and details from the past. Scientists have long debated whether this gradual decline is an early form of Alzheimer’s disease—a neurodegenerative condition that leads to severe dementia—or a distinct neurological process. Now, researchers have found a protein that distinguishes typical forgetfulness from Alzheimer’s and could lead to potential treatments for age-related memory loss. Previous studies have shown that Alzheimer’s disease and age-related memory loss involve different neural circuits in the hippocampus, a seahorse-shaped structure in the brain...

People were fascinated by the idea, and in the three decades since, bookstores, television, the Internet and college psychology classes everywhere have been filled with endless discussions of the differences between right-brain, left-brain, and whole-brain thinkers.

There weren't any overall differences between the high- and low-flavanol groups in terms of cognitive abilities, so the researchers looked a little deeper.

Scientists have created a false memory in mice by manipulating neurons that bear the memory of a place. The work further demonstrates just how unreliable memory can be. It also lays new ground for understanding the cell behavior and circuitry that controls memory, and could one day help researchers discover new ways to treat mental illnesses...

The company, which uses its search, email and other services to funnel personalised advertising to users, is currently trialling prototypes of its Glass device, which is worn like a pair of glasses. But Google is staking its future on a new service which will use the information it holds on registered users to automatically predict their search needs and present them with the data they want. The ultimate ambition is to literally get inside...

    Pennsylvania scientists have discovered the cause of the chronic disorder known as tinnitus, and have also found a way to treat it. Their goal is a preventive strategy for individuals whose work situations could cause them to be exposed to very loud noise. University of Pittsburgh School of Medicine researchers found that an epilepsy drug known as retigabine prevents tinnitus in animal models, according to ScienceDaily. They published their findings in the Proceedings of the National Academy of Sciences. Strictly speaking, tinnitus isn't a condition, but a symptom of some type of disorder, like hearing loss related to age, a...

    The daredevil teen awoke from his sodium-induced coma after three days.A young man who drank a quart of soy sauce went into a coma and nearly died from an excess of salt in his body, according to a recent case report. The 19-year-old, who drank the soy sauce after being dared by friends, is the first person known to have deliberately overdosed on such a high amount of salt and survived with no lasting neurological problems, according to the doctors in Virginia who reported his case. The case report was published online June 4 in the Journal of Emergency Medicine....

    Inside a Mouse's Brain Lies a Chemical Key to the Fountain of Youth By Greg Thomas Source image via Wikipedia If a scientist came to you with a plan to tweak a gland in the center of your brain so that you may live to be 140 years old, you'd probably back out of the room slowly and go to file a police report, because that's creepy. But new research shows that it's not altogether impossible. A new report from researchers at the Albert Einstein School of Medicine in the Bronx shows that scientists can tinker with the minds of...

    The taste of beer, without any effect from alcohol itself, can trigger dopamine release in the brain that is associated with drinking and other drugs of abuse, researchers have claimed. Using positron emission tomography (PET), the researchers at Indiana University School of Medicine tested 49 men with two scans, one in which they tasted beer, and the second in which they tasted Gatorade. The researchers were looking for evidence of increased levels of dopamine, a brain neurotransmitter that has long been associated with alcohol and other drugs of abuse. The scans showed significantly more dopamine activity following the taste of...

    New York - Scientists have for the first time linked the brains of a human and a rat, enabling the man to use just his thoughts to wiggle the rodent's tail. This is the first case of a brain-to-brain interface between species, and the first example of a noninvasive brain-to-brain interface, researchers claimed. Earlier this year, scientists had linked together the brains of two rats.This first known instance of a brain-to-brain interface apparently helped the rodents share data to accomplish certain tasks, even across intercontinental distances, LiveScience reported. In the latest experiment, researchers from Harvard Medical School employed noninvasive techniques...

    Yesterday was filled with big doin’s around here. MO did a movie review while, down the hall, BO addressed the importance of having a brain. Lady M, as part of her continuing series of culturally sensitive movie reviews, held a film workshop on the movie “42.” “42” is a biopic about Jackie Robinson, the baseball player who broke the Major League’s color barrier in 1947 (he also was a successful business man after his baseball career butt he didn’t do that on his own). Jackie’s wife, Rachael Robinson, was in attendance along with the film’s stars Harrison Ford, and other...
