Do you know why it is so fiendishly difficult to quit smoking – because of a faulty receptor in the brain. It can lead to an uncontrollable desire to smoke, thanks to the defect in a receptor protein normally activated by nicotine, which curbs the desire for yet more of the drug. The team found [...]

Physical exercise may be the best way to keep your brain sharp in old age, says a study. In recent years there has been a sales boom in so-called “brain training” computer games and puzzles. But now researchers suggest keeping physically fit may be more important than mental work-outs, reports express.co.uk. It was found that [...]
Smoking can reduce thickness of the brain

A new study has found that smoking can reduce the thickness of the human brain. Researchers compared cortical thickness in volunteers, both smokers and never-smokers, who were without medical or psychiatric illnesses. Smokers exhibited cortical thinning in the left medial orbitofrontal cortex and heavier smoking was associated with more pronounced thinning of cortical tissue. The [...]
Sugar-sweetened coffee ‘boosts memory, attention span’

Sugar-sweetened coffee may be the best way to prepare the brain for a busy day ahead, say scientists. Researchers at the University of Barcelona in Spain found that taking caffeine and sugar at the same time boosted the brain’s performance more than taking them on their own. They now believe each one boosts the effect [...]

The way diseases of the psyche are diagnosed is changing rapidly. Doctors are struggling to keep up
WHAT good is a diagnostic tool if it is too complicated for doctors to use? This is the dilemma facing psychiatry. In the United States the release back in February of a draft version of the latest edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-V) has triggered a furious row over whether this tool has become too complex. Meanwhile, the World Health Organisation (WHO) points out that more than three-quarters of people with brain disorders in the developing world are not being treated, and on October 7th it released simplified guidelines for diagnosis and treatment designed especially for use by the front-line in medicine: primary-care doctors.
These developments highlight a revolution in psychiatry, the last bastion of symptom-based medicine. In no other medical domain is the symptom (say, anxiety) also the diagnosis. There is a reason for this: the brain is a complex organ and the causes of its disorders remain poorly understood. But thanks to brain imaging and genetics, that is changing fast. …

Stimulating the brain delays, but does not prevent, dementia
AS THE baby-boomer generation contemplates the prospect of the Zimmer frame there has never been more interest in delaying the process of ageing. One consequence has been a dramatic rise in the popularity of brain-training games. But how effective really is a daily dose of cryptic crossword?
Robert Wilson, a neuropsychologist at Rush University in Chicago, and his colleagues decided to find out, by following a group of people without dementia. Participants were asked to rate how frequently they engaged in cognitively stimulating activities. The researchers were looking for such things as reading newspapers, books and magazines, playing challenging games like chess, listening to the radio and watching television, and visiting museums. …
Innovation@Intel: 48-Core Single-Chip Cloud Computer – Reading Brain Waves with Computers
June 15th, 2010 |
No Comments
Imagine future laptops capable of vision comparable to the human eye, accurately seeing objects and motion. You could shop online using the laptop’s 3D camera and display and see a “mirror image” of yourself wearing the clothes you are “trying on,” seeing how the fabric drapes when you move or twirl and how the color complements your skin tone. Researchers from Intel Labs recently demonstrated (PDF 652KB) a experimental 48-core Intel microprocessor that could make this and much more a reality. Some researchers believe future computers with processors derived from this chip may even be able to read brain waves – where simply thinking about a command could make it happen. The long-term goal of the 48-core microprocessor is to add scaling features to computers in order to spur entirely new software applications and human-machine interfaces. Intel presented a paper on this technology at this week’s 2010 Symposia on VLSI Technology and Circuits. Read more about the “Single-Chip Cloud Computer” (PDF 1.15MB) in Microprocessor Report and see more about how Intel innovation is changing the way we work, live, and play.

The wonders of docosahexaenoic acid
TO PIN one big evolutionary shift on a particular molecule is ambitious. To pin two on it is truly audacious. Yet doing so was just one of the ideas floating around at “A Celebration of DHA” in London this week. The celebration in question was a scientific meeting, rather than a festival. It was definitely, however, a love-in. It was held on May 26th and 27th at the Royal Society of Medicine to discuss the many virtues of docosahexaenoic acid, the most important of that fashionable class of dietary chemicals, the omega-3 fatty acids.
DHA is a component of brains, particularly the synaptic junctions between nerve cells, and its displacement from modern diets by the omega-6 acids in cooking oils such as soya, maize and rape is a cause of worry. Many researchers think this shift—and the change in brain chemistry that it causes—explains the growth in recent times of depression, manic-depression, memory loss, schizophrenia and attention-deficit disorder. It may also be responsible for rising levels of obesity and thus the heart disease which often accompanies being overweight. …
