    Karolinska Institute (SWEDEN) ^ | Nov 10, 2009 | Karlen, Olson, et. al.
    [PRESS RELEASE, 10 November 2009] Researchers at Karolinska Institutet have discovered a mechanism that controls the brain's ability to create lasting memories. In experiments on genetically manipulated mice, they were able to switch on and off the animals' ability to form lasting memories by adding a substance to their drinking water. The findings, which are published in the scientific journal PNAS, are of potential significance to the future treatment of Alzheimer's and stroke.

    Red-eye flights, all-night study sessions, and extra-inning playoff games all deprive us of sleep and can leave us forgetful the next day. Now scientists have discovered that lost sleep disrupts a specific molecule in the brain's memory circuitry, possibly leading to treatments for tired brains. Neuroscientists studying rodents and humans have found that sleep deprivation interrupts the storage of episodic memories: information about who, what, when, and where. To lay down these memories, neurons in our brains form new connections with other neurons or strengthen old ones. This rewiring process, which occurs over a period of hours, requires a rat's...

    Implant false memories by 'seizing control of circuits. Posted in Biology, 16th October 2009 13:43 GMT An alliance of boffins from Oxford University and Virginia, America say they have developed a technique for "writing directly to memory" in a living brain, "seizing control of brain circuits" to create a memory of an experience which had never actually happened. Thus far, according to the research, the technique works reliably only on flies. "Flies have the ability to learn, but the circuits that instruct memory formation were unknown," says Oxford insect-brain expert Gero Miesenböck. "We were able to pin the essential component...

    (July 20) - You probably recall little of your days in the womb, but a new study suggests that short-term memory may be present in fetuses at 30 weeks of age. Until a few decades ago, "people would say that the human fetus is a sort of black box," said Dr. Jan Nijhuis, a co-author of the study and an obstetrician at Maastricht University Medical Center in The Netherlands. Studies over the years have started to reveal more about the neurological development of humans before they are born, but researchers are still trying to figure out when memory begins and...

    Researchers have found that taking a supplement of omega 3 for six months had a beneficial effect on people with age-related forgetfulness and loss of learning ability. They tested the affect of docosahexaenoic acid (DHA), which is most commonly found in fish oil, on 485 healthy people and found that memory and general brain function increased significantly. The research, based on volunteers with an average age of 70, showed taking 900mg capsules every day was the equivalent of turning back the clock three years, it was found. Now it is hoped that further studies could show that the fatty acid...

    SAN FRANCISCO — Maybe it’s time to retire the “senior moment.” These lapses of memory during everyday life — losing your keys or your train of thought — are thought to be more common in older people. Not so, researchers from the University of Waterloo in Canada report March 21 at the annual meeting of the Cognitive Neuroscience Society. Researcher Amanda Clark and her colleagues surveyed 30 adults younger than 25 and 24 people ages 60 to 80 to find out how many slips they make each day. The researchers also devised two lab tests to study attention. One involved...

Medical researchers have identified brain activity that causes older adults to remember fewer negative events than their younger counterparts. Neuroscientists from Duke University Medical Center have discovered that older people use their brains differently than younger people when it comes to storing memories, particularly those associated with negative emotions.

    DRAM makers are facing one of the worst downturns in their history and governments around the world are lining up to help companies through the mess. Taiwan, Germany and South Korea all appear poised to offer some assistance to their DRAM chip makers. The need could not be greater. Long before the global financial crisis hit, DRAM makers suffered steep sales declines due to a glut of their chips. DRAM prices are now at rock bottom and companies are cutting back production instead of making more chips at such steep losses. The next few weeks will be the best time...

He knew that his father’s family came from Thibodaux, La., and his mother was from Ireland, and he knew about the 1929 stock market crash and World War II and life in the 1940s. But he could remember almost nothing after that. In 1953, he underwent an experimental brain operation in Hartford to correct a seizure disorder, only to emerge from it fundamentally and irreparably changed. He developed a syndrome neurologists call profound amnesia. He had lost the ability to form new memories. For the next 55 years, each time he...

    Scientists have for the first time recorded individual brain cells in the act of summoning a spontaneous memory, revealing not only where a remembered experience is registered but also, in part, how the brain is able to recreate it. The recordings, taken from the brains of epilepsy patients being prepared for surgery, demonstrate that these spontaneous memories reside in some of the same neurons that fired most furiously when the recalled event had been experienced. Researchers had long theorized as much but until now had only indirect evidence. Experts said the study had all but closed the case: For the...

    LONDON (Reuters) - Eating tuna and other fatty fish may help prevent memory loss in addition to reducing the risk of stroke, Finnish researchers said on Monday. People who ate baked or broiled -- but not fried -- fish high in omega-3 fatty acids have been found to be less likely to have "silent" brain lesions that can cause memory loss and dementia and are linked to a higher risk of stroke, said Jyrki Virtanen of the University of Kuopio in Finland.

A daily capsule of rember, as the drug is known, stops Alzheimer’s disease progressing by as much as 81 per cent, according to trial results. Patients with the brain disorder had no significant decline in their mental function over a 19-month period. ‘We appear to be bringing the worst affected parts of the brain functionally back to life,’ said Dr Claude Wischik, who led the research.

While men may fail to match a woman's ability to remember the date of an anniversary, they are better at storing a seemingly endless cache of facts and figures and all this is because of genetic differences. Researchers at the Institute of Psychiatry, King's College London, have found that males use different genes from females when making the new connections in the brain that are needed to create long-term memories.

    A new study has found that it may be possible to train people to be more intelligent, increasing the brainpower they had at birth. Until now, it had been widely assumed that the kind of mental ability that allows us to solve new problems without having any relevant previous experience — what psychologists call fluid intelligence — is innate and cannot be taught (though people can raise their grades on tests of it by practicing). But in the new study, researchers describe a method for improving this skill, along with experiments to prove it works. The key, researchers found, was...

    How much would you pay to have a small memory chip implanted in your brain if that chip would double the capacity of your short-term memory? Or guarantee that you would never again forget a face or a name? There’s good reason to consider such offers. Although our memories are sometimes spectacular — we are very good at recognizing photos, for example — our memory capacities are often disappointing. Faulty memories have been known to lead to erroneous eyewitness testimony (and false imprisonment), to marital friction (in the form of overlooked anniversaries) and even death (sky divers have been known...

IBM scientists unveiled a major breakthrough in their effort to build a new class of memory, nicknamed "racetrack." A diagram of the nanowire shows how an electric current is used to slide -- or "race" – tiny magnetic patterns around the nanowire "track," where the device can read and write data in less than a nanosecond. The racetrack memory would stand billions of nanowires,...

Michael Alkire and Larry Cahill at the University of California in Irvine have discovered that anaesthetics can block the formation of memories associated with emotive images. "One popular misconception about anaesthesia is that unconsciousness occurs immediately," says Alkire. In fact, low doses of anaesthetic can leave patients conscious but impede memory, he says.

"Of all the successors to George Washington, none had a bigger impact on the presidency and the country." Bush spoke in early tribute to the 199th anniversary of Lincoln's birthday. Lincoln was born Feb 12, 1809. On Tuesday, first lady Laura Bush will speak at Lincoln's birthplace of Hodgenville, Ky., as part of the...

    Most of the problem solving we do in order to get through a day involves the use of what's referred to as "working memory." it acts a bit like RAM; we store information we need for the task at hand temporarily, but don't necessarily commit it to permanent memory. A recent study has probed the qualities of visual working memory, and has come to the conclusion that we have a finite and well-defined capacity for visual items, a finding that may have far-reaching implications for one simple reason: that capacity may be what's stressed by IQ tests. The study appeared...
  • I'm the chimpion! Ape trounces the best of the human world in memory competition

    When scientists found out that chimps had better memories than students, there were unkind comments about the calibre of the human competition they faced. But now an ape has gone one better, trouncing British memory champion Ben Pridmore. Ayumu, a seven-year-old male brought up in captivity in Japan, did three times as well as Mr Pridmore at a computer game which involved remembering the position of numbers on a screen. And that's no mean feat - the 30-year-old accountant from Derby is capable of memorising the order of a shuffled pack of cards in under 30 seconds.
  • Lack Of Imagination In Older Adults Linked To Declining Memory

    Lack Of Imagination In Older Adults Linked To Declining Memory ScienceDaily (Jan. 8, 2008) — Most children are able to imagine their future selves as astronauts, politicians or even superheroes; however, many older adults find it difficult to recollect past events, let alone generate new ones. A new Harvard University study reveals that the ability of older adults to form imaginary scenarios is linked to their ability to recall detailed memories. According to the study, episodic memory, which represents our personal memories of past experiences, "allows individuals to project themselves both backward and forward in subjective time." Therefore, in order...
  • Mental Reserves Keep Brains Agile

    My husband, at 74, is the baby of his bridge group, which includes a woman of 85 and a man of 89. This challenging game demands an excellent memory (for bids, cards played, rules and so on) and an ability to think strategically and read subtle psychological cues. Never having had a head for cards, I continue to be amazed by the mental agility of these septua- and octogenarians. The brain, like every other part of the body, changes with age, and those changes can impede clear thinking and memory. Yet many older people seem to remain sharp as a...

    Young chimpanzee can recall number placement better than people can. A particularly cunning seven-year-old chimp named Ayumu has bested university students at a game of memory. He and two other young chimps recalled the placement of numbers flashed onto a computer screen faster and more accurately than humans. “It’s a very simple fact: chimpanzees are better than us — at this task,” says Tetsuro Matsuzawa, a primatologist at Kyoto University in Japan who led the study. The work doesn't mean that chimps are 'smarter' than humans, but rather they seem to be better at memorizing a snapshot view of their...

    Chimpanzees have an extraordinary photographic memory that is far superior to ours, research suggests. Young chimps outperformed university students in memory tests devised by Japanese scientists. The tasks involved remembering the location of numbers on a screen, and correctly recalling the sequence. The findings, published in Current Biology, suggest we may have under-estimated the intelligence of our closest living relatives. Until now, it had always been assumed that chimps could not match humans in memory and other mental skills. "There are still many people, including many biologists, who believe that humans are superior to chimpanzees in all cognitive functions," said...
  • Stem Cells May Reverse Brain Injury and Restore Memory

    Memories help construct lives and life experiences—without them, living life would be nearly impossible. Alzheimer’s and Parkinson’s diseases are debilitating illnesses capable of ruining victims’ lives and inflicting pain and sadness on their families. Recent findings at UC Irvine show that the use of stem cells can reverse memory loss after brain injuries and diseases, such as Alzheimer’s. “This study can very well benefit people with diseases such as Alzheimer’s and Parkinson’s, as well as physical brain injuries and neuron loss, if it becomes transferable to humans,” said Debbie Morisette, a stereologist working on the study. “But as of right...

    Your brain can distinguish between real and fake memories, even if you can’t. Tell the truth: our brain can sometimes reveal if our memories are real or false.stockbyteIt’s a common situation: you’re embroiled in an argument over a fact and you know for certain that you have the right answer. But when someone rushes to their laptop to google the correct answer, you discover that you were wrong. Whether in a fight with a spouse or giving testimony on the witness stand, it is clear that our memories are not always trustworthy. Now, researchers have found that although those vivid...

    The task looks as simple as a “Sesame Street” exercise. Study pairs of Easter eggs on a computer screen and memorize how the computer has arranged them: the aqua egg over the rainbow one, the paisley over the coral one — and there are just six eggs in all. Most people can study these pairs for about 20 minutes and ace a test on them, even a day later. But they’re much less accurate in choosing between two eggs that have not been directly compared: Aqua trumped rainbow but does that mean it trumps paisley? It’s hazy. It’s hazy, that...
