Two minutes of magnetic stimulation can change your brain for an hour
A couple of minutes is all it takes to 'knock out' bits of your brain for an hour, according to a new study by a University College London (UCL) team. The team have been working on ways to improve a method known as transcranial magnetic stimulation (TMS) and are now using their adapted version of TMS to investigate possible treatments for stroke... view more...

Common gene version optimizes thinking — but with a possible downside
Most people inherit a version of a gene that optimizes their brain's thinking circuitry, yet also appears to increase risk for schizophrenia, a severe mental illness marked by impaired thinking, scientists at the National Institutes of Health's (NIH) National Institute of Mental Health (NIMH) have discovered. view more (2007-02-09)
Human-dog communication -- breed as important as species
Dog breeds selected to work in visual contact with humans, such as sheep dogs and gun dogs, are better able to comprehend a pointing gesture than those breeds that usually work without direct supervision. view more (2009-07-24)
Is sleep 'hard-wired' into the brain?
Falling asleep is usually thought of as something we can control ourselves as part of our behaviour patterns. In a new article in the December Journal of the Royal Society of Medicine, Dr Bidi Evans argues that waking and sleeping is actually controlled by a physical mechanism that is 'hard-wired' into the brain. She suggests that evidence from... view more... (2002-11-25)
Seeing colors -- New study sheds light on sensory system quirk
In the psychological phenomenon known as "synesthesia," individuals' sensory systems are a bit more intertwined than usual. Some people, for example, report seeing colors when musical notes are played. view more (2007-07-25)
The worldwide prevalence of glaucoma is increasing (p 1711)
Early diagnosis of glaucoma is essential to prevent irreversible visual impairment, according to a Seminar in this week's issue of THE LANCET. Glaucoma is a group of disorders that progressively damage the optic nerve in the eye and without treatment can cause visual disability and eventual blindness. Glaucoma affects more than 66 million people... view more... (2004-05-19)
Adults with lazy eye can improve
Young adults with amblyopia, or lazy eye, can improve substantially and retain their gains under a new treatment developed by researchers at USC and three Chinese universities. view more (2005-12-21)
Siblings of schizophrenia patients display subtle shape abnormalities in brain
Subtle malformations in the brains of patients with schizophrenia also tend to occur in their healthy siblings, according to investigators at the Silvio Conte Center for the Neuroscience of Mental Disorders at Washington University School of Medicine in St. Louis. view more (2008-02-20)
Infants can organise visual information at just four months
Research investigating attention in infancy has revealed that, at just four months old, babies are able to organise visual information in at least three different ways, according to brightness, shape, and how close the visual elements are together (proximity). view more (2006-04-28)
Madison Avenue Magic: Study Reveals Positive Effects of Unconscious Exposure to Advertisements
Fads have been a staple of American pop culture for decades, from spandex in the 1980s to skinny jeans today. But while going from fad to flop may seem like the result of fickle consumers, a new study suggests that this is exactly what should be expected for a highly efficient, rationally evolved animal. view more (2008-12-10)
Turfgrass quality measurement improved with GreenSeeker sensor
To measure turfgrass performance, professionals have traditionally relied on trained human evaluators who provide visual assessments of turf quality. view more (2009-09-09)
Why C is not G: How we identify letters
The next time you are reading a book, or even as you read this article, consider the words that you are seeing. How do you recognize these words? Substantial research has shown that while reading, we recognize words by their letters and not by the general shape of the word. view more (2008-11-26)
Research at Rice may help explain aspects of synesthesia
A research team led by Rice University Psychology Professor Tony Ro has published its findings that may help to explain the phenomenon known as synesthesia, in which stimulation of one sensory pathway leads to automatic, involuntary experiences in a second sensory pathway. view more (2007-09-26)
Resemblance between cataplexy during status cataplecticus, normal REM sleep
The first efforts to identify the neural structures and pathways underlying cataplexy during status cataplecticus in a narcoleptic patient, with the use of brain perfusion single photon emission computed tomography (SPECT), have led to the discovery that cataplexy during status cataplecticus, a case of prolonged cataplexy, partially resembles... view more...

Dopamine study sheds new light on drug addiction
A paper published in today's issue of Science has challenged beliefs about the role of dopamine in the brain, which could lead to new treatments for Parkinson's disease, schizophrenia and drug addiction. The research suggests that dopamine has a far wider, less specialised role than previously hypothesised. view more (2005-03-02)
Neural bottleneck found that thwarts multi-tasking
Many people think they can safely drive while talking on their cell phones. Vanderbilt neuroscientists Paul E. Dux and René Marois have found that when it comes to handling two things at once, your brain, while fast, isn't that fast. view more (2007-01-19)
Big Brother is Watching You
Big Brother is really watching you and his name is Jeremiah. Jeremiah, like most people, likes company and a hive of activity and hates being ignored or bored. The only thing is, he is not a human being, but a virtual head which is capable of locating, monitoring and reacting to your movements. Jeremiah reacts to visual stimuli. His eyes and head... view more... (2002-02-19)
Caltech scientists find evidence for precise communication across brain areas during sleep
By listening in on the chatter between neurons in various parts of the brain, researchers from the California Institute of Technology (Caltech) have taken steps toward fully understanding just how memories are formed, transferred, and ultimately stored in the brain--and how that process varies throughout the various stages of sleep. view more (2009-02-26)
Discovery of post-stimulus activated release implies new mechanisms for dopamine release
The neurotransmitter dopamine continues to be released for nearly an hour after neurons are stimulated, suggesting the existence of secondary mechanisms that allow for sustained availability of dopamine in different regions of the brain including areas critical for memory consolidation, drug induced plasticity and maintaining active networks... view more...

Study charts origins of fear
A team of researchers led by the University of Toronto has charted how and where a painful event becomes permanently etched in the brain - a discovery that has implications for pain-related emotional disorders such as anxiety and post-traumatic stress. view more (2005-09-16)
