Decoding Funny Faces to Detect Disease
Like Russell Crowe's character in A Beautiful Mind, life is often difficult for the 2.4 million Americans with schizophrenia. A late or incorrect diagnosis and the lack of effective treatment options can destroy a sufferer's quality of life. view more (2009-02-05)
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)
Natural protein stops deadly human brain cancer in mice
Scientists from Johns Hopkins and from the University of Milan have effectively proven that they can inhibit lethal human brain cancers in mice using a protein that selectively induces positive changes in the activity of cells that behave like cancer stem cells. view more (2006-12-08)
Great (taste) expectations: Study shows brain anticipates taste, shifts gears
As the prism of our senses, the human brain has ways of refracting sensory input in defiance of reality. view more (2006-02-22)
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...

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)
Experts discuss use of human stem cells in ape and monkey brains
An expert panel of stem cell scientists, primatologists, philosophers and lawyers has concluded that experiments implanting, or grafting, human stem cells into non-human primate brains could unintentionally shift the moral ground between humans and other primates. view more (2005-07-15)
Feeling empathy for a loved-one: empathy for pain activates pain-sensitive regions of the brain, says UCL study
Knowing our partner is in pain automatically triggers affective pain processing regions of our brains, according to new research by University College London (UCL) scientists. The study, published in the 20th February edition of the journal Science, asked whether empathizing with the pain of others involves the re-activation of the entire pain... view more... (2004-02-19)
DNA variations linked to brain tumors
Mayo Clinic researchers and colleagues at the University of California San Francisco (UCSF) have found a connection between DNA alterations on human chromosome 9 and aggressive brain cancer known as glioblastoma. view more (2009-07-06)
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)
Brain power goes green
Our brains, it turns out, are eco-friendly. A study published in Science and reviewed by F1000 Biology members Venkatesh Murthy and Jakob Sorensen reveals that our brains have the amazing ability to be energy efficient. view more (2009-10-15)
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)
Active genes discovered in the developing mammal brain
A study by scientists at Penn State provides new information about the genes that are involved in a mammal's early brain development, including those that contribute to neurological disorders. view more (2009-07-14)
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)
Ultrasound affects embryonic mouse brain development
The prolonged and frequent use of ultrasound on pregnant mice causes brain abnormalities in the developing mouse fetus. view more (2006-08-08)
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)
High-tech research shows cocaine changes proteins and brain function
In the first large-scale analysis of proteins in the brains of individuals addicted to cocaine, researchers have uncovered novel proteins and mechanisms that may one day lead to new treatment options to fight addiction. view more (2006-11-01)
Monkeys' calls - the beginnings of human language?
Rhesus macaques communicate between themselves using a complex series of sounds that can signify things as distinct as the presence of danger, particular social relationships, emotions or food alerts. Now scientists in the latest issue of Proceedings of the National Academy of Sciences of the United States of America, while analyzing the brain... view more... (2004-12-17)
Can we 'learn to see?': Study shows perception of invisible stimuli improves with training
Although we assume we can see everything in our field of vision, the brain actually picks and chooses the stimuli that come into our consciousness. view more (2009-10-22)
