Growth of new brain cells requires 'epigenetic' switch
New cells are born every day in the brain's hippocampus, but what controls this birth has remained a mystery. Reporting in the January 1 issue of Science, neuroscientists at the Johns Hopkins University School of Medicine have discovered that the birth of new cells, which depends on brain activity, also depends on a protein that is involved in... view more...

Sex-based prenatal brain differences found
Prenatal sex-based biological differences extend to genetic expression in cerebral cortices. The differences in question are probably associated with later divergences in how our brains develop. view more (2009-10-26)
60 second test could help early diagnosis of common brain diseases
Until recently physicians have had to rely on time-consuming and uncertain behavioural examinations to diagnose the onset of brain diseases such as multiple sclerosis, Alzheimer's and schizophrenia. view more (2007-08-22)
Violent video games leave teenagers emotionally aroused
A new study has found that adolescents who play violent video games may exhibit lingering effects on brain function, including increased activity in the region of the brain that governs emotional arousal and decreased activity in the brain's executive function, which is associated with control, focus and concentration. view more (2006-11-29)
Stress-induced levels of corticotropin-releasing factor responsible for binge behaviour
Stressed individuals might be particularly prone to binge eating or drug addiction because of the high levels of the stress hormone corticotropin-releasing factor in their brain. view more (2006-04-13)
Uncovering the molecular basis of obesity
Why does the same diet make some of us gain more weight than others? view more (2007-06-06)
Protein's potential as a regulator of brain activity discovered
UC Irvine researchers have found that a protein best known for building connections between nerve cells and muscle also plays a role in controlling brain cell activity. view more (2006-04-21)
Researchers find potential treatment for Huntington's disease
Investigators at Burnham Institute for Medical Research (Burnham), the University of British Columbia's Centre for Molecular Medicine and Therapeutics and the University of California, San Diego have found that normal synaptic activity in nerve cells (the electrical activity in the brain that allows nerve cells to communicate with one another)... view more...

Babies see it coming
Do infants only start to crawl once they are physically able to see danger coming? Or is it that because they are more mobile, they develop the ability to sense looming danger? view more (2009-09-24)
Social reasoning and brain development are linked in preschoolers -- Queen's study
New research at Queen's University shows that the way preschool children understand false beliefs can be linked to particular aspects of brain development. view more (2009-07-16)
tudy: The new buzz on detecting tinnitus
It's a ringing, a buzzing, a hissing or a clicking - and the patient is the only one who can hear it. Complicating matters, physicians can rarely pinpoint the source of tinnitus, a chronic ringing of the head or ears that can be as quiet as a whisper or as loud as a jackhammer. view more (2009-10-05)
Food or its expectation sparks brain's hunger centers
The concept of whetting the appetite by serving hors d'oeuvres before a meal may have a solid scientific basis. view more (2006-10-04)
A frown or a smile? Children with autism can't discern
When we have a conversation with someone, we not only hear what they say, we see what they say. Eyes can smolder or twinkle. Gazes can be direct or shifty. "Reading" these facial expressions gives context and meaning to the words we hear. view more (2007-05-07)
Brain Scan Study of Smokers Reveals Signature of Craving
Not all smokers are alike when it comes to cravings, and a new study conducted by researchers at Duke University Medical Center suggests the difference may lie in their brains' sensitivity to drug cues. view more (2005-06-29)
'Speed of thought' guides brain's memory consolidation
Scientists at The University of Arizona have added another piece of the puzzle of how the brain processes memory. view more (2007-11-16)
MIT neuroscientists find neural stopwatch in the brain
MIT researchers have identified populations of neurons that code time with extreme precision in the primate brain. These neurons are found in two interconnected brain regions, the prefrontal cortex and the striatum, both of which are known to play critical roles in learning, movement, and thought control. view more (2009-10-20)
Gladstone scientists uncover potential mechanism of memory loss in Alzheimer's disease
Researchers at the Gladstone Institute of Neurological Disease (GIND) and Baylor College of Medicine have discovered a mechanism by which the protein Amyloid-beta(AB) may impair neurological functions in Alzheimer's disease. view more (2007-09-06)
Pitt research identifies new target in brain for treating schizophrenia
Research from the University of Pittsburgh could expand the options for controlling schizophrenia by identifying a brain region that responds to more than one type of antipsychotic drug. view more (2008-11-06)
Brain regions do not communicate efficiently in adults with autism
A novel look at the brains of adults with autism has provided new evidence that various brain regions of people with the developmental disorder may not communicate with each other as efficiently as they do in other people. view more (2006-10-16)
Selflessness - The Core of All Major World Religions - Has Neuropsychological Connection, MU Study Finds
All spiritual experiences are based in the brain. That statement is truer than ever before, according to a University of Missouri neuropsychologist. view more (2008-12-18)
