Sleeping minds: prepare to be hacked. For the first time, conscious memories have been implanted into the minds of mice while they sleep. The same technique could one day be used to alter memories in people who have undergone traumatic events. When we sleep, our brain replays the day's activities. The pattern of brain activity exhibited by mice when they explore a new area during the day, for example, will reappear, speeded up, while the animal sleeps. This is thought to be the brain practising an activity - an essential part of learning. People who miss out on sleep do...

Dogs Don't Remember: Episodic Memory May Distinguish Humans Dogs are wonderful creatures. Our dogs recognize me and are always happy to see me. Dogs are also smart and successful creatures. Our dogs have learned several cute tricks. But dogs (and other non-human animals) are missing something we take for granted: episodic memory. Dogs don't remember what happened yesterday and don't plan for tomorrow. In defining episodic memory, Endel Tulving argued that it is unique to humans. Experience influences all animals. Most mammals and birds can build complex sets of knowledge or semantic memory. You and I also remember the experience...

Scientists have discovered the key to stopping Alzheimer’s disease in its earliest stages. The breakthrough paves the way for a ‘statin-like’ drug that could be taken by millions to prevent dementia. Cambridge University researchers have found a naturally occurring molecule that can slow the formation of plaques in the brain. Amyloid plaques are closely associated with declining memory and other Alzheimer’s symptoms. The discovery raises the prospect of a treatment which could be routinely taken in middle age to stop dementia. It could even result in a pill that could be used to treat dementia in the same way that...

A skull that's more than three and a half millennia old has revealed signs of an early form of brain surgery. The perforated skull belongs to a mummified woman found in the Xiaohe tomb in China's Xinjiang Uygur Autonomous Region. Experts said that the hole, which measures around 2 inches (50mm) in diameter, was most likely an early form of craniotomy. A craniotomy involves temporarily removing a 'flap' of bone from the skull to give surgeons access to the brain. The amount of skull removed depends on the type of surgery being performed, and the flap is later replaced using...

Beer could help 'protect brain against Parkinson's and Alzheimer's' " As self-delusional arguments go, it sounds like it is up there with claims that a bowl of ice-cream supplies a quarter of your daily calcium needs. However, scientists in China have found that drinking beer could help protect the brain from a number of degenerative brain diseases. A team of researchers at Lanzhou University have published a study which claims that xanthohumol, a type of flavinoid found in hops, could help protect the brain against the onset of diseases such as Parkinson's, Alzheimer's and dementia. According to Jianguo Fang,...

“Cutting through disinformation about consciousness is vital, because neuroscience is moving toward a mind-controlled society, based on the idea that individual awareness is an illusion, and stimulus-response is the key to shaping a new Collective of synchronized ‘happy’ brains.”

One of the most promising new treatments for Alzheimer's disease may already be in your kitchen. Curcumin, a natural product found in the spice turmeric, has been used by many Asian cultures for centuries, and a new study indicates a close chemical analog of curcumin has properties that may make it useful as a treatment for the brain disease. "Curcumin has demonstrated ability to enter the brain, bind and destroy the beta-amyloid plaques present in Alzheimer's with reduced toxicity," said Wellington Pham, Ph.D., assistant professor of Radiology and Radiological Sciences and Biomedical Engineering at Vanderbilt and senior author of the...

Massachusetts Institute of Technology scientists examining the intricate network of brain cells that underlie sight, thought, and psychiatric disease had a running joke in the laboratory: let’s just make everything bigger. If they could simply enlarge brain cells, they reasoned, the task of mapping the circuits would be easier. Now, they have found a way to do just that, using a technique that has shades of a 1950s science fiction movie. But instead of spawning killer ants or a 50-foot giantess, the researchers have found a controlled way to cause a tissue sample swell to roughly four and a half...

U.S. scientists have identified a molecular network of genes known to contribute to autism spectrum disorders, and they say their finding may help uncover new genes linked to these conditions. "The study of autism disorders is extremely challenging due to the large number of clinical mutations that occur in hundreds of different human genes associated with autism," study author Michael Snyder, genetics and personalized medicine professor at Stanford University, said in a news release. "We therefore wanted to see to what extent shared molecular pathways are perturbed by the diverse set of mutations linked to autism in the hope of...

Patients with chronic fatigue syndrome are accustomed to disappointment. The cause of the disorder remains unknown; it can be difficult to diagnose, and treatment options are few. Many patients are still told to seek psychiatric help. But two recent studies — one from investigators at Stanford a few weeks ago and another from a Japanese research team published earlier this year — have found that the brains of people with chronic fatigue syndrome differ from those of healthy people, strengthening the argument that serious physiological dysfunctions are at the root of the condition. Both studies were small, however, and their...

AUSTIN, Texas (AP) — The University of Texas at Austin is missing about 100 brains — about half of the specimens the university had in a collection of brains preserved in jars of formaldehyde. One of the missing brains is believed to have belonged to clock tower sniper Charles Whitman. "We think somebody may have taken the brains, but we don't know at all for sure," psychology Professor Tim Schallert, co-curator of the collection, told the Austin American-Statesman (http://bit.ly/11R7vym ). His co-curator, psychology Professor Lawrence Cormack, said, "It's entirely possible word got around among undergraduates and people started swiping them...

Are we on the brink of creating artificial life? Scientists digitise the brain of a WORM and place it inside a robot The OpenWorm global project is making a 'digital' worm Their project is recreating the neurons and cells in C. elegans It is the simplest organism we know of but has similarities to humans By making a digital worm the team hope to create artificial life They have implanted the digital 'mind' of the worm into a Lego machine In a video it acts and behaves just like the worm would in the real world Next year the team...

**SNIP** The amendment's author, Republican Senator Charles Grassley, argued that if Obamacare plans were good enough for the American public, they were good enough for Congress. Democrats, eager to pass the reforms, went along with it. But it soon became apparent the provision contained no language that allowed federal contributions toward their health plans that cover about 75 percent of the premium costs. This caused fears that staff would suddenly face sharply higher healthcare costs and leave federal service, causing a "brain drain" on Capitol Hill. But Wednesday's proposed rule from the OPM, the federal government's human resources agency, means...

Researchers from the Center for BrainHealth at The University of Texas at Dallas have found evidence that the effects of chronic marijuana use may depend on when a person started smoking pot and for how long. For the study, which was published in the journal Proceedings of the National Academy of Sciences on Nov. 10, Francesca Filbey from the School of Behavioral and Brain Sciences at the University of Texas at Dallas, and colleagues involved 48 adult marijuana users who started to use weed when they were between 14 and 30 years old. The participants smoked pot thrice a day...

Experimental mice have been telling us this for years, but pot-smoking humans didn't want to believe it could happen to them: Compared with a person who never smoked marijuana, someone who uses marijuana regularly has, on average, less gray matter in his orbital frontal cortex, a region that is a key node in the brain's reward, motivation, decision-making and addictive behaviors network. More ambiguously, in regular pot smokers, that region is better connected than it is in non-users:The flow of signal traffic is speedier to other parts of that motivation and decision-making network, including across the superhighway of "white matter"...

A cancer sufferer achieved her dream of playing in her first college basketball game on Sunday, scoring the first points of the match. Mount St Joseph freshman Lauren Hill, 19, was diagnosed last year with an inoperable brain tumor and was told she had years to live. In September, doctors had a grim update - she wouldn't make it past December - and after years as a standout high school basketball player, Hill's hopes of playing college ball were put in jeopardy.

In case anyone needed another reason to love chocolate, a new study suggests that a natural compound found in cocoa, tea and some vegetables can reverse age-related memory loss. The findings suggest that the compound increases connectivity and, subsequently, blood flow in a region of the brain critical to memory, the researchers said. Researchers said that if a person had the memory of a typical 60-year-old at the beginning of the study, after three months, on average, that person’s memory would function more like a 30- or 40-year-old’s. The researchers also cautioned that more work is needed because of the...

Brain Bath: A Clever Design Solution by Brian Thomas, M.S. * What makes sleep so mentally refreshing? University of Rochester neuroscientist Jeff Iliff addressed the crowd gathered at a September 2014 TEDMED event and explained his amazing new discoveries.1 The words he used perfectly match what one would expect while describing the works of an ingenious designer.2 Other organs rely on the lymphatic system to remove metabolic waste that builds up in the spaces outside cells, but no lymph vessels exist behind the skull. Since the brain uses a fourth of all the body’s energy, there must be some other...

The new research could help doctors to quickly identify patients who are aware despite appearing unresponsive and unable to communicate. Researchers from University of Cambridge in the UK have identified hidden networks in vegetative patients that could support consciousness, even when a patient appear to be unresponsive. There’s been a lot of interest lately into how much patients in vegetative states, such as comas, are aware of their surroundings. Recently, research involving functional magnetic resonance imaging (fMRI) scanning has shown that even patients who are unable to respond or move are able to carry out mental tasks, such as imagining...
