Children's diet not the main cause of ADHD
Food may not be the major cause of hyperactivity in children. Genetics, brain function and parental actions such as smoking may be just as important. view more (2008-05-30)
New Technique For Measuring Blood Flow To Brain In Babies (p 1749)
Authors of a research letter in this week's issue of THE LANCET describe how an ultrasound technique can be used as a non-invasive way of measuring blood flow to the brain in babies, which may be of benefit to infants with brain disorders arising from restrictions in cerebral blood flow. Changes in the rate of blood flow to the brain in premature... view more... (2002-11-27)
Whole-brain radiotherapy after surgery or radiosurgery not recommended for brain metastases
Whole-brain radiotherapy should not be given routinely to all patients whose cancer has spread to the brain, say researchers who found that using it after surgery or radiosurgery in patients with a limited number of brain metastases and stable cancer in the rest of the body did not extend lives or help patients remain functionally independent for... view more...

Gene tied to longevity also preserves ability to think clearly
A gene variant linked to living a very long life-to 90 and beyond-also serves to help very old people think clearly and retain their memories, according to new research by scientists at the Albert Einstein College of Medicine of Yeshiva University. view more (2006-12-26)
Scientists learn what's 'up' with a class of retinal cells in mice
Harvard University researchers have discovered a new type of retinal cell that plays an exclusive and unusual role in mice: detecting upward motion. The cells reflect their function in the physical arrangement of their dendrites, branch-like structures on neuronal cells that form a communicative network with other dendrites and neurons in the... view more...

Stereotactic radiosurgery preferred method of treating cancer patients with brain metastases
Cancer patients who receive stereotactic radiosurgery (SRS) and whole brain radiation therapy (WBRT) for the treatment of metastatic brain tumors have more than twice the risk of developing learning and memory problems than those treated with SRS alone, according to researchers at The University of Texas M. D. Anderson Cancer Center. view more (2009-10-06)
Bigger brain size matters for intellectual ability
Brain size matters for intellectual ability and bigger is better, McMaster University researchers have found. view more (2005-12-23)
Potential new approach to treat cognitive impairments in schizophrenia
A new study reports important evidence for a potential new treatment approach for those diagnosed with schizophrenia. Schizophrenia is considered one of the most devastating of the major psychiatric disorders, which has three distinct facets, often referred to as "positive" (hallucinations, delusions), "negative" (blunted... view more...

Study provides new insights into brain organisation
Scientists have provided new insights into how the brain is organised-knowledge which could eventually inform diagnosis of and treatments for conditions like Alzheimer's Disease and autism. view more (2006-08-02)
Study finds genomic changes in the brains of people who commit suicide
Are genes destiny? Alternatively, are we simply the products of our environment? There is a growing sense that neither of these two possibilities fully captures the essence of the risk for psychiatric disorders. view more (2008-10-23)
Neuroscientists Show Insulin Receptor Signaling Regulates Structure and Function of Brain Circuits
A team of neuroscientists at Cold Spring Harbor Laboratory (CSHL) has demonstrated for the first time in living animals that insulin receptors in the brain can initiate signaling that regulates both the structure and function of neural circuits. view more (2008-06-19)
Bioluminescence at the service of a novel cerebral imaging technique
CNRS scientists in collaboration have developed a new technique for the in vivo imaging of neuronal function using bioluminescence, based on a GFP-aequorin fusion protein. view more (2007-04-17)
Researchers find a key mechanism in the development of nerve cells
Chaos brews in the brains of newborns: the nerve cells are still bound only loosely to each other. view more (2009-09-30)
Autism the focus for students
The highly respected international speaker, Professor Simon Baron-Cohen will be presenting his world-renowned research on autism to the next generation of psychologists at the British Psychological Society's Student Member Group Conference, today, Saturday 17 April. view more (2004-04-19)
Scans show learning 'sculpts' the brain's connections
Spontaneous brain activity formerly thought to be "white noise" measurably changes after a person learns a new task, researchers at Washington University School of Medicine in St. Louis and the University of Chieti, Italy, have shown. view more (2009-10-09)
Brain cells work differently than previously thought
Scientists know that information travels between brain cells along hairlike extensions called axons. For the first time, researchers have found that axons don't just transmit information - they can turn the signal up or down with the right stimulation. view more (2007-08-20)
Damage to specific part of the brain may make smokers 'forget' to smoke
Preliminary research supported by the National Institute on Drug Abuse (NIDA), a component of the National Institutes of Health, has found that some smokers with damage to a part of the brain called the insula may have their addiction to nicotine practically eliminated. view more (2007-01-29)
Mental and physical exercise delays dementia in fatal genetic disease
Scientists at Melbourne's Howard Florey Institute have discovered that mental and physical stimulation delays the onset of dementia in the fatal genetic disease, Huntington's disease. view more (2008-01-24)
Bigger not necessarily better, when it comes to brains
Tiny insects could be as intelligent as much bigger animals, despite only having a brain the size of a pinhead, say scientists at Queen Mary, University of London. view more (2009-11-18)
New brain cells listen before they talk
Newly created neurons in adults rely on signals from distant brain regions to regulate their maturation and survival before they can communicate with existing neighboring cells-a finding that has important implications for the use of adult neural stem cells to replace brain cells lost by trauma or neurodegeneration, Yale School of Medicine... view more...
