New radiation technique helps brain cancer patients keep their hair
Patients whose cancer has spread to the brain can avoid typical hair loss (alopecia) when treated with newer radiation techniques, thereby improving their quality of life while still controlling their cancer. view more (2005-10-17)
Dying of excitement
For neurons, overexcitement is deadly. To avoid this, brain cells must sop up unneeded neurotransmitters from the synapse through membrane-bound transporters. If these transporters fail, neurons and other brain cells get excited to death- a phenomenon that may contribute to brain damage during stroke and Alzheimer's disease. view more (2006-03-06)
Toward a nanomedicine for brain cancer
In an advance toward better treatments for the most serious form of brain cancer, scientists in Illinois are reporting development of the first nanoparticles that seek out and destroy brain cancer cells without damaging nearby healthy cells. view more (2009-09-10)
Link between Alzheimer's disease and traumatic brain damage clarified
This week scientists of the Flanders Interuniversity Institute for Biotechnology (VIB) will once again publish a breakthrough in their research regarding Alzheimer's disease. view more (2005-08-04)
Human influences challenge penguin populations
The ecology of penguins makes these iconic swimming and diving seabirds of the Southern Hemisphere unusually susceptible to environmental changes. view more (2008-07-01)
Building the blood-brain barrier
Construction of the brain's border fence is supervised by Wnt/b-catenin signaling, report Liebner et al. in The Journal of Cell Biology. view more (2008-10-27)
Prenatal meth exposure linked to abnormal brain development
A first of its kind study examining the effects of methamphetamine use during pregnancy has found the drug appears to cause abnormal brain development in children. view more (2009-04-16)
Mechanism Behind Stuttering Revealed (p 380)
Stuttering is caused by a structural abnormality in the left hemisphere of the brain, according to an article in this week's LANCET. Dr Martin Sommer and colleagues from the Universities of Hamburg and Göttingen in Germany report that persistent developmental stuttering results from a disconnection of speech-related areas in the cortex.... view more...

Fast and slow — How the spinal cord controls the speed of movement
Using a state-of-the-art technique to map neurons in the spinal cord of a larval zebrafish, Cornell University scientists have found a surprising pattern of activity that regulates the speed of the fish's movement. view more (2007-03-01)
Evidence appears to show how and where frontal lobe works
A Brown University study of stroke victims has produced evidence that the frontal lobe of the human brain controls decision-making along a continuum from abstract to concrete, from front to back. view more (2009-03-02)
Seeing what we are thinking
At last we can see ourselves thinking, using the technique known as functional brain imaging (fMRI), and some of the exciting developments in this field were described in a series of papers presented today, Thursday 29 March, at The British Psychological Society's Centenary Annual Conference, held at the SECC, Glasgow. Dr Adrian Owen, of the... view more... (2001-03-26)
Breast cancer subtypes linked to survival from secondary brain tumors
Screening breast cancers for three receptors could help doctors predict the likely survival of patients with brain metastases. view more (2008-02-28)
New EMBO/NPG journal - A first in systems biology publishing
Molecular Systems Biology, a new electronic journal from the European Molecular Biology Organization (EMBO) and Nature Publishing Group (NPG), is now live at http://www.molecularsystemsbiology.com. view more (2005-04-15)
Gene variations linked to brain aneurysms
Variations in a gene seem to be linked to brain (cerebral) aneurysms, suggests research published ahead of print in the Journal of Neurology Neurosurgery and Psychiatry. view more (2006-04-27)
Researchers identify a cell type that limits stroke damage
A research team including Serge Rivest of University Laval's Faculty of Medicine has demonstrated the existence of a type of cells that limits brain damage after a stroke. The study was recently published in the online version of Nature Medicine. view more (2009-01-28)
Changes in brain density can help predict schizophrenia
Changes in brain density could be used to predict whether an individual who is at risk for schizophrenia is likely to develop the condition or not. view more (2006-12-07)
Direct recording shows brain signal persists even in dreamless sleep
Neuroscientists at Washington University School of Medicine in St. Louis have taken one of the first direct looks at one of the human brain's most fundamental "foundations": a brain signal that never switches off and may support many cognitive functions. view more (2008-10-01)
Preventing overload in the brain
Brain researchers in Amsterdam have observed a double control system in the hippocampus. This double control system contributes to the memory and ensures that the brain does not `crash`, as is the case during an epileptic seizure. The neurobiologists from the University of Amsterdam carried out their observations on the hippocampus of rats. The... view more... (2002-01-29)
Scientists identify brain regions that decide where we look
Scientists have found the brain regions that decide where we look, and where to direct our eyes when we're faced with a difficult choice, such as looking someone straight in the eye or looking away. view more (2005-01-24)
UBC scientist unveils secret of newborn's first words
A new study could explain why "daddy" and "mommy" are often a baby's first words - the human brain may be hard-wired to recognize certain repetition patterns. view more (2008-08-27)
