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)
LOWER TEEN PREGNANCY RATES IN PRACTICES WITH YOUNG FEMALE DOCTORS
Hippisley-Cox and colleagues, from the Division of General Practice, University of Nottingham, looked at the numbers of teen pregnancies for each of the 826 general practices in the Trent region between 1994 and 1997. The Trent region has one of the highest teen pregnancy rates in the UK. view more (2000-03-21)
Club drugs inflict damage similar to traumatic brain injury
What do suffering a traumatic brain injury and using club drugs have in common"? University of Florida researchers say both may trigger a similar chemical chain reaction in the brain, leading to cell death, memory loss and potentially irreversible brain damage. view more (2007-11-30)
Study Finds Needle Biopsies Safe in 'Eloquent' Areas of Brain
After a review of 284 cases, specialists at the Brain Tumor Center at the University of Cincinnati (UC) Neuroscience Institute have concluded that performing a stereotactic needle biopsy in an area of the brain associated with language or other important functions carries no greater risk than a similar biopsy in a less critical area of the brain. view more (2009-06-04)
Where the brain organizes actions
Researchers have discovered that Broca's area in the brain—best known as the region that evolved to manage speech production—is a major "executive" center in the brain for organizing hierarchies of behaviors. view more (2006-06-15)
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)
Cell death in sparrow brains may provide clues in age-related human diseases
A remarkable change takes place in the brains of tiny songbirds every year, and some day the mechanism controlling that change may help researchers develop treatments for age-related degenerative diseases of the brain such as Parkinson's and dementia. view more (2007-09-18)
Big picture of brain changes may be crucial to recovery from stroke injury
A study of patients who have difficulty paying attention to the left side of their environment has provided some of the first direct evidence that brain injury can cause detrimental functional changes in brain regions far from the site of the actual injury. view more (2005-10-18)
'Faulty' brain connections may be responsible for social impairments in autism
New evidence shows that the brains of adults with autism are "wired" differently from people without the disorder, and this abnormal pattern of connectivity may be responsible for the social impairments that are characteristic of autism. view more (2008-06-13)
Unlikely genetic suspect implicated in common brain defect
A genetic search that wound its way from patients to mouse models and back to patients has uncovered an unlikely gene critically involved in a common birth defect which causes mental retardation, motor delays and sometimes autism, providing a new mechanism and potentially improving treatment for the disorder. view more (2009-08-10)
Expectant brains help predict anxiety treatment success
A network of emotion-regulating brain regions implicated in the pathological worry that can grip patients with anxiety disorders may also be useful for predicting the benefits of treatment. view more (2009-01-05)
Brain activity reflects differences in types of anxiety
All anxiety is not created equal, and a research team at the University of Illinois now has the data to prove it. view more (2007-05-30)
Sight, sound processed together and earlier than previously thought
The area of the brain that processes sounds entering the ears also appears to process stimulus entering the eyes, providing a novel explanation for why many viewers believe that ventriloquists have thrown their voices to the mouths of their dummies. view more (2007-10-30)
New golden frog discovered in remote region of Colombia
A new poisonous frog was recently discovered in a remote mountainous region in Colombia by a team of young scientists supported by the Conservation Leadership Programme (CLP). view more (2007-08-29)
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...

Study of nutrients' effects on brain provides insight into appetite regulation
A cell-signaling pathway in the brain that is linked to the development of cancer and diabetes is also a key part of networks that regulate food intake, say University of Cincinnati (UC) researchers. view more (2006-05-12)
Is brain size linked to two common gene variants?
Human brain size is hereditary, but the genes that influence brain size in healthy people are unknown. view more (2006-05-17)
Brain activation can predict the strategies people use to make risky decisions
Watching people's brains in real time as they handle a set of decision-making problems can reveal how different each person's strategy can be, according to neuroscientists at the Duke University Medical Center. view more (2009-05-28)
Study shows that color plays musical chairs in the brain
Color is normally thought of as a fundamental attribute of an object: a red Corvette, a blue lake, a pink flamingo. Yet despite this popular notion, new research suggests that our perception of color is malleable, and relies heavily on biological processes of the eye and brain. view more (2009-10-02)
Mobile phone use not linked to increased risk of glioma brain tumours
Mobile phones are not associated with an increased risk of the most common type of brain tumour, finds the first UK study of the relationship between mobile phone use and risk of glioma. view more (2006-01-20)
