New methods for brain research
Novel methods of measuring magnetic fields outside the head give further insights to the functioning of the human brain. In his doctoral thesis "Estimating Neural Currents from Neuromagnetic Measurements", Kimmo Uutela developed new methods for finding electrical activity of the brain, which enable easier identification of different... view more...

Sunlight and serotonin underlie seasonal mood disorders
Authors of a research letter in this week's issue of THE LANCET provide further evidence that the effect of sunlight on neurotransmitters in the brain plays a significant role in seasonal mood disorders. The success of phototherapy (ultraviolet light therapy to stimulate brain neurotransmitter activity) and drugs that prevent the reuptake of the... view more... (2002-11-29)
Foster care may boost brain activity of institutionalized children
Children raised in institutions are more likely to lag physically, socially, and cognitively, but little is known about what happens to children's brains when they live in institutions. view more (2009-07-15)
Researchers find link between improved memory and the use of neurofeedback
Scientists from Imperial College London and Charing Cross Hospital believe that it may be possible to improve memory by up to 10 percent through the use of neurofeedback. The results announced in the International Journal of Psychophysiology this month show a link between neurofeedback training and improved memory in a 40 person trial. Dr David... view more...

Parts of brain involved in social cognition may be in place by age 6
Social cognition-the ability to think about the minds and mental states of others-is essential for human beings. In the last decade, a group of regions has been discovered in the human brain that are specifically used for social cognition. view more (2009-07-15)
Battle of the bulge: Low leptin levels undermine successful weight loss
Individuals who are obese are at increased risk of many diseases, including type 2 diabetes and heart disease. As 75%-95% of previously obese individuals regain their lost weight, many researchers are interested in developing treatments to help individuals maintain their weight loss. view more (2008-06-23)
Blink, and the brain misses it
We would immediately notice if the outside world suddenly went dark every few seconds. But we rarely become aware of our blinks, even though they cause a similar reduction in the amount of light entering the eye. So why are we not aware of the frequent mini-blackouts caused by blinks? view more (2005-07-26)
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)
Scientists find how neural activity spurs blood flow in the brain
New research from Harvard University neuroscientists has pinpointed exactly how neural activity boosts blood flow to the brain. The finding has important implications for our understanding of common brain imaging techniques such as fMRI, which uses blood flow in the brain as a proxy for neural activity. view more (2008-06-26)
Moderate alcohol consumption enhances the formation of new nerve cells - may contribute to alcohol dependency
Moderate alcohol consumption over a relatively long period of time can enhance the formation of new nerve cells in the adult brain. The new cells could prove important in the development of alcohol dependency and other long-term effects of alcohol on the brain. The findings are published by Karolinska Institutet. view more (2005-04-26)
Researchers find alcoholics display abnormal brain activity when processing facial expressions
Researchers from Boston University School of Medicine (BUSM) have found that individuals who have a long history of alcoholism, but who have been abstinent for at least a month up to many years, showed abnormal brain activity when looking at facial expressions of others. view more (2009-08-11)
Asleep or awake we retain memory
Sleeping helps to reinforce what we've learned. And brain scans have revealed that cerebral activity associated with learning new information is replayed during sleep. view more (2006-03-28)
When neurons fire up: Study sheds light on rhythms of the brain
In our brains, groups of neurons fire up simultaneously for just milliseconds at a time, in random rhythms, similar to twinkling lightning bugs in our backyards. New research from neuroscientists at Indiana University and the University of Montreal provides a model -- a rhyme and reason -- for this random synchronization. view more (2008-08-06)
Twins study shows genetic basis for face and place recognition
New evidence suggests our brains are hardwired before birth to recognize faces and places. But in contrast, the neural circuitry we use to recognize words develops mainly as a result of experience. view more (2007-12-20)
Mobile microscopes illuminate the brain
The majority of our life is spent moving around a static world and we generate our impression of the world using visual and other senses simultaneously. view more (2009-11-03)
New findings shed light on why smokers struggle to quit
Just seeing someone smoke can trigger smokers to abandon their nascent efforts to kick the habit, according to new research conducted at Duke University Medical Center. view more (2009-01-06)
The brain 'joins the dots' when drawing a cartoon face from memory
In a study by Miall, Gowen and Tchalenko published by Elsevier, in the March issue of Cortex, a brain scanner was used to record the brain's activity in each stage of the process of drawing faces. view more (2009-03-19)
Strength of connections between brain regions may affect an adolescent's response to peer influence
Brain regions that regulate different aspects of behavior are more interconnected in children with high resistance to peer influence than those with low resistance, according to a new study published in the July 25 issue of The Journal of Neuroscience. view more (2007-07-27)
Phantoms in the brain: Pain after amputation
Losing a limb can be a traumatic experience and, in some cases, emotional and physical pain can linger for years. view more (2008-05-13)
Research Breakthrough In Understanding Treatment-Resistant Depression
CLINICAL NEUROSCIENCE CENTRE: DARTFORD UK A pioneering research study using brain imaging has yielded new clues to help sufferers from severe depression who do not respond to conventional treatment. Around 5 million people in the UK experience depression at any one time. Whilst a number of successful treatments, both pharmacological and... view more... (2003-10-01)
