Brain, behavior may have changed as social insect colonies evolved
A new study suggests that brain and behavior relationships may have changed in a profound way as larger, more complex insect societies evolved from smaller, simpler ones. view more (2006-11-16)
Age-related difficulty recognizing words predicted by brain differences
Older adults may have difficulty understanding speech because of age-related changes in brain tissue, according to new research in the May 13 issue of The Journal of Neuroscience. view more (2009-05-13)
The Conflict of Reward in Depression
In Love and Death, Woody Allen wrote: "To love is to suffer-To be happy is to love. To be happy, then, is to suffer." The paradoxical merging of happiness and suffering can be a feature of depression. view more (2008-03-26)
New gene for dyslexia located
No gene for dyslexia has been isolated until now, although scientists have long suspected a genetic basis for the disorder and have even roughly mapped the region of the brain likely to be involved. The researchers anticipate that they will now be able to clone the genetic sequence and so gain important insights into the processes involved in... view more... (1999-09-02)
Numerical processing similar in children and adults, brain scans reveal
Four-year-olds who are still developing numerical abilities show activity in the same brain region during numerical tasks as do math-adept adults, Duke University researchers have found. view more (2006-04-11)
The MARSIS radar estimates the volume of water in the south pole of Mars
By studying the South Polar region of Mars, the MARSIS (Mars Advanced Radar for Subsurface and Ionospheric Sounding) radar of the Mars Express space probe has enabled the structure of the layered deposits of this region to be elucidated. view more (2007-04-02)
Cancer researchers confirm brain tumor genetic subtype informs treatment, predicts outcome
Research confirms that determining the genetic composition of brain cancers can better inform doctors and patients for treatment options and prognosis. The findings could change the future of how cancers are diagnosed. view more (2006-07-07)
Sleep and sedation controlled in same brain centre, say scientists
Undergoing anaesthesia may be more like falling asleep than we once thought, according to new research from Imperial College London and Harvard Medical School, USA. Researchers report today in the journal Nature Neuroscience how two of the most widely used anaesthetics, pentobarbital and propofol induce sleep by mimicking the natural process of... view more...

New study by Rice University psychologist finds women's brains recognize, encode smell of male sexual sweat
A new Rice University study published in the Journal of Neuroscience found that socioemotional meanings, including sexual ones, are conveyed in human sweat. view more (2009-01-08)
MIT: Stem-cell therapies for brain more complicated than thought
An MIT research team's latest finding suggests that stem cell therapies for the brain could be much more complicated than previously thought. view more (2007-11-28)
Why delaying gratification is smart: A neural link between intelligence and self-control
If you had a choice between receiving $1,000 right now or $4,000 ten years from now, which would you pick? Psychologists use the term "delay discounting" to describe our inability to resist the temptation of a smaller immediate reward in lieu of receiving a larger reward at a later date. view more (2008-09-10)
3-D ultrasound scanner provides in-depth view of the brain
Biomedical engineers at Duke's Pratt School of Engineering have adapted a three-dimensional ultrasound scanner that might guide minimally invasive brain surgeries and provide better detection of a brain tumor's location. view more (2007-06-21)
Pain in fibromyalgia is linked to changes in brain molecule
Researchers at the University of Michigan Health System have found a key linkage between pain and a specific brain molecule, a discovery that lends new insight into fibromyalgia, an often-baffling chronic pain condition. view more (2008-03-11)
MRI study opens door to assessing, preventing dangerous brain iron levels
A magnetic resonance imaging (MRI) study at UCLA opens new doors to assessing and potentially preventing brain iron accumulation associated with risk of developing degenerative brain diseases such as Alzheimer's, Parkinson's and Dementia With Lewy Bodies. view more (2006-03-27)
Brain activity linked to the parental instinct
Why do we almost instinctively treat babies as special, protecting them and enabling them to survive" Darwin originally pointed out that there is something about infants which prompts adults to respond to and care for them which allows our species to survive. view more (2008-02-27)
Duck-billed dinosaur crests not linked to sense of smell
After decades of debate, a U of T researcher has finally determined that duck-billed dinosaurs' massive but hollow crests had nothing to do with what many scientists suspected - the sense of smell. view more (2006-01-25)
Scientists find brain function most important to maths ability
Scientists at UCL (University College London) have discovered the area of the brain linked to dyscalculia, a maths learning disability. view more (2006-03-07)
Researchers uncover mechanism of action of antibiotic able to reduce neuronal cell death in brain
Virginia Commonwealth University researchers have discovered how an antibiotic works to modulate the activity of a neurotransmitter that regulates brain functions, which eventually could lead to therapies to treat Alzheimer's disease, Huntington's disease, epilepsy, stroke, dementia and malignant gliomas. view more (2008-05-12)
Researchers discover that gene switches on during development of epilepsy
A discovery made by researchers at Wake Forest University School of Medicine while studying mice may help explain how some people without a genetic predisposition to epilepsy can develop the disorder. view more (2009-04-23)
Proteins in urine predict brain damage in laboratory animals
The study dealt with the development and prevention of strokes in particular rats which had spontaneously developed extremely high blood pressure. Such a high blood pressure level leads within a few weeks to damage to the kidneys, heart and brain such that the rats die. The researchers found that brain damage in these rats is always preceded by... view more... (1999-06-21)
