Miracle teabag – containing stem cells – helps stroke victim to speak again

A stroke victim has regained the power of speech after doctors placed a device resembling a teabag filled with stem cells in his brain.

Walter Bast, 49, also regained the use of his right arm after the revolutionary treatment, which prevents brain cells from dying.

If further trials of the treatment are successful, it could be on the market in as little as five years, providing fresh hope for the 45,000 Britons each year who suffer a haemorrhagic stroke, where a blood vessel in the brain bursts.

Currently, the only option is surgery, which has a variable success rate. Half of surgery patients will die within a month and just one in 20 patients will recover to the extent of Mr Bast.

The pioneering treatment, called CellBeads, involves cutting away part of the skull to tie off leaking blood vessels and remove blood from the brain.

Surgeons then insert the 2cm by 2cm ‘teabag’ filled with capsules stuffed with around a million stem cells.

The stem cells, taken from bone marrow, have been genetically engineered to make a drug known as CM1 that protects brain cells from dying. This lets the cells rejuvenate and repair the damage done by the stroke.

After around two weeks, doctors at the International Neuroscience-Institute in Hanover, Germany, removed the ‘teabag’, resulting in Mr Bast regaining his speech and the use of his right arm.

Speaking a week after the operation, the first of its kind in the world, Mr Bast, a mechanic, said: “I feel a lucky guy.”

Music Shown to Facilitate the Development of Neurons in the Brain


Mozart Requiem (KV 626)

(NaturalNews) Music, the universal language of mood, emotion and desire, connects with us through a wide variety of neural systems. Researchers have discovered evidence that music stimulates specific regions of the brain responsible for memory, language and motor control. They have located specific areas of mental activity linked to the emotional responses elicited by music. Now new research conclusions have identified how the affect of music could replicate the effects of hormone replacement therapy in the prevention of Alzheimer’s disease and dementia.

The August 7 issue of Medical Hypotheses reports these conclusions resulting from experience that has shown music to be useful in therapy for neuropsychiatric disorders resulting from both functional and organic origins. However, the mechanisms of the action of music on the brain have remained largely unknown despite an increase in scientific studies on the topic.

The results of past studies have clarified that music influences and affects cranial nerves in humans from fetus to adult. To explain how it works at the cellular level, researchers proposed that the neurogenesis, regeneration and repair of the cerebral nerves are the result of adjustments through the secretion of steroid hormones ultimately leading to cerebral plasticity.

The Army’s Totally Serious Mind-Control Project


Army scientists want to cram this array of brain-wave reading sensors into a helmet.

Soldiers barking orders at each other is so 20th Century. That’s why the U.S. Army has just awarded a $4 million contract to begin developing “thought helmets” that would harness silent brain waves for secure communication among troops. Ultimately, the Army hopes the project will “lead to direct mental control of military systems by thought alone.”

If this sounds insane, it would have been as recently as a few years ago. But improvements in computing power and a better understanding of how the brain works have scientists busy hunting for the distinctive neural fingerprints that flash through a brain when a person is talking to himself. The Army’s initial goal is to capture those brain waves with incredibly sophisticated software that then translates the waves into audible radio messages for other troops in the field. “It’d be radio without a microphone, ” says Dr. Elmar Schmeisser, the Army neuroscientist overseeing the program. “Because soldiers are already trained to talk in clean, clear and formulaic ways, it would be a very small step to have them think that way.”

Tiny Cellular Antennae Trigger Neural Stem Cells

ScienceDaily (Aug. 25, 2008) – Yale University scientists today reported evidence suggesting that the tiny cilia found on brain cells of mammals, thought to be vestiges of a primeval past, actually play a critical role in relaying molecular signals that spur creation of neurons in an area of the brain involved in mood, learning and memory.

The cilia found on brain cells of mammals until recently had been viewed as a mysterious remnant of a distant evolutionary past, when the tiny hair-like structures were used by single-celled organisms to navigate a primordial world.

“Many neuroscientists are shocked to learn that cells in the brain have cilia. Thus it was even more exciting to show that cilia have a key function in regulating the birth of new neurons in the brain,” said Matthew Sarkisian, post doctoral fellow in the department of neurobiology and co-first author on the study.

Uncle Sam Wants Your Brain

Drugs that make soldiers want to fight. Robots linked directly to their controllers’ brains. Lie-detecting scans administered to terrorist suspects as they cross U.S. borders.

These are just a few of the military uses imagined for cognitive science — and if it’s not yet certain whether the technologies will work, the military is certainly taking them very seriously.

“It’s way too early to know which — if any — of these technologies is going to be practical,” said Jonathan Moreno, a Center for American Progress bioethicist and author of Mind Wars: Brain Research and National Defense. “But it’s important for us to get ahead of the curve. Soldiers are always on the cutting edge of new technologies.”

Moreno is part of a National Research Council committee convened by the Department of Defense to evaluate the military potential of brain science. Their report, “Emerging Cognitive Neuroscience and Related Technologies,” was released today. It charts a range of cognitive technologies that are potentially powerful — and, perhaps, powerfully troubling.

Here are the report’s main areas of focus:

Scientists stop the ageing process

There is more to life. The human body was not designed to “fall apart”.

Nobel Prize winner Dr. Alexis Carrel was able to keep cells from a chicken heart alive and replicating new cells for 28 years, far outliving the life of a chicken which is 7 to 12 years. The cells did not die of aging they simply terminated the experiment.

“The cell is immortal. It is merely the fluid in which it floats that degenerates. Renew this fluid at regular intervals, give the cell what it requires for nutrition, and as far as we know, the pulsation of life can go on forever.” – Dr. Alexis Carroll, Nobel Prize Winner

Clean bill of health: Scientists have shown that clearing damaged protein from the liver helps stop age decline in the organ (Source: iStockphoto)

Scientists have stopped the ageing process in an entire organ for the first time, a study released today says.

Published in today’s online edition of Nature Medicine, researchers at the Albert Einstein College of Medicine at Yeshiva University in New York City also say the older organs function as well as they did when the host animal was younger.

The researchers, led by Associate Professor Ana Maria Cuervo, blocked the ageing process in mice livers by stopping the build-up of harmful proteins inside the organ’s cells.

PTSD leaves physical footprints on the brain

At a recent conference for some of the area’s leading neurologists, San Francisco physicist Norbert Schuff captured his colleagues’ attention when he presented colorful brain images of U.S. soldiers who had returned from Iraq and Afghanistan and were diagnosed with post-traumatic stress disorder.

The yellow areas, Schuff explained during his presentation at the city’s Veterans Affairs Medical Center, showed where the hippocampus, which plays major roles in short-term memory and emotions, had atrophied. The red swatches marked hyperfusion – increased blood flow – in the prefrontal cortex, the region responsible for conflict resolution and decision-making. Compared with a soldier without the affliction, the PTSD brain had lost 5 to 10 percent of its gray matter volume, indicating yet more neuron damage.

The REAL brain drain: Modern technology – including violent video games – is changing the way our brains work, says neuroscientist

Human identity, the idea that defines each and every one of us, could be facing an unprecedented crisis.

It is a crisis that would threaten long-held notions of who we are, what we do and how we behave. It goes right to the heart – or the head – of us all.

This crisis could reshape how we interact with each other, alter what makes us happy, and modify our capacity for reaching our full potential as individuals.

And it’s caused by one simple fact: the human brain, that most sensitive of organs, is under threat from the modern world.


Video games are weakening the ability to think for ourselves

Unless we wake up to the damage that the gadget-filled, pharmaceutically-enhanced 21st century is doing to our brains, we could be sleepwalking towards a future in which neuro-chip technology blurs the line between living and non-living machines, and between our bodies and the outside world.

It would be a world where such devices could enhance our muscle power, or our senses, beyond the norm, and where we all take a daily cocktail of drugs to control our moods and performance.

Already, an electronic chip is being developed that could allow a paralysed patient to move a robotic limb just by thinking about it.

As for drug manipulated moods, they’re already with us – although so far only to a medically prescribed extent.

Increasing numbers of people already take Prozac for depression, Paxil as an antidote for shyness, and give Ritalin to children to improve their concentration.

But what if there were still more pills to enhance or “correct” a range of other specific mental functions?

What would such aspirations to be “perfect” or “better” do to our notions of identity, and what would it do to those who could not get their hands on the pills? Would some finally have become more equal than others, as George Orwell always feared?

The Government Is Trying to Wrap Its Mind Around Yours

Imagine a world of streets lined with video cameras that alert authorities to any suspicious activity. A world where police officers can read the minds of potential criminals and arrest them before they commit any crimes. A world in which a suspect who lies under questioning gets nabbed immediately because his brain has given him away.

Though that may sound a lot like the plot of the 2002 movie “Minority Report,” starring Tom Cruise and based on a Philip K. Dick novel, I’m not talking about science fiction here; it turns out we’re not so far away from that world. But does it sound like a very safe place, or a very scary one?

It’s a question I think we should be asking as the federal government invests millions of dollars in emerging technology aimed at detecting and decoding brain activity. And though government funding focuses on military uses for these new gizmos, they can and do end up in the hands of civilian law enforcement and in commercial applications. As spending continues and neurotechnology advances, that imagined world is no longer the stuff of science fiction or futuristic movies, and we postpone at our peril confronting the ethical and legal dilemmas it poses for a society that values not just personal safety but civil liberty as well.

Consider Cernium Corp.’s “Perceptrak” video surveillance and monitoring system, recently installed by Johns Hopkins University, among others. This technology grew out of a project funded by the Defense Advanced Research Projects Agency — the central research and development organization for the Department of Defense — to develop intelligent video analytics systems. Unlike simple video cameras monitored by security guards, Perceptrak integrates video cameras with an intelligent computer video. It uses algorithms to analyze streaming video and detect suspicious activities, such as people loitering in a secure area, a group converging or someone leaving a package unattended. Since installing Perceptrak, Johns Hopkins has reported a 25 percent reduction in crime.

But that’s only the beginning. Police may soon be able to monitor suspicious brain activity from a distance as well. New neurotechnology soon may be able to detect a person who is particularly nervous, in possession of guilty knowledge or, in the more distant future, to detect a person thinking, “Only one hour until the bomb explodes.” Today, the science of detecting and decoding brain activity is in its infancy. But various government agencies are funding the development of technology to detect brain activity remotely and are hoping to eventually decode what someone is thinking. Scientists, however, wildly disagree about the accuracy of brain imaging technology, what brain activity may mean and especially whether brain activity can be detected from afar.

Yet as the experts argue about the scientific limitations of remote brain detection, this chilling science fiction may already be a reality. In 2002, the Electronic Privacy Information Center reported that NASA was developing brain monitoring devices for airports and was seeking to use noninvasive sensors in passenger gates to collect the electronic signals emitted by passengers’ brains. Scientists scoffed at the reports, arguing that to do what NASA was proposing required that an electroencephalogram (EEG) be physically attached to the scalp.

Neuromarketing could make mind reading the ad-man’s ultimate tool

Neuroscience and marketing had a love child a few years back. Its name – big surprise – is neuromarketing, and the ugly little fellow is growing up. Corporate pitchmen have always wanted to get inside our skulls. The more accurately they can predict how we’ll react to stimuli in the marketplace, from prices to packages to adverts, the more money they can pull from our pockets and transfer to their employers’ coffers.

But picking the brains of consumers hasn’t been easy. Marketers have had to rely on indirect methods to read our thoughts and feelings. They’ve watched what we do in stores or tracked how purchases rise or fall in response to promotional campaigns or changes in pricing. And they’ve carried out endless surveys and focus groups, asking us what we buy and why.

The results have been mixed at best. People, for one thing, don’t always know what they’re thinking, and even when they do, they’re not always honest in reporting it. Traditional market research is fraught with bias and imprecision, which forces companies to fall back on hunches and rules of thumb.

But thanks to recent breakthroughs in brain science, companies can now actually see what goes on inside our minds when we shop. Teams of academic and corporate neuromarketers have begun to hook people up to functional magnetic resonance imaging (fMRI) machines to map how their neurons respond to products and pitches.

Can a thinking, remembering, decision-making, biologically accurate brain be built from a supercomputer?

Out of the Blue

Can a thinking, remembering, decision-making, biologically accurate brain be built from a supercomputer?

In the basement of a university in Lausanne, Switzerland sit four black boxes, each about the size of a refrigerator, and filled with 2,000 IBM microchips stacked in repeating rows. Together they form the processing core of a machine that can handle 22.8 trillion operations per second. It contains no moving parts and is eerily silent. When the computer is turned on, the only thing you can hear is the continuous sigh of the massive air conditioner. This is Blue Brain.
