Methylmercury warning
Recent studies hint that exposure to the toxic chemicals, such as methylmercury can cause harm at levels previously considered safe. view more (2008-10-29)
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)
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)
Testing your reflexes until you've had enough
Can't squeeze in another mouthful? Feeling full is all a question of reflexes, according to Leeds biomedical researcher Dr David Lewis. He hopes to open the way for new therapies to treat obesity, by looking at how, why and when our brain tells our stomach it's had enough. The basic reflexes controlling eating are centred in the hindbrain - the... view more... (2002-05-20)
You will remember this
Scientists can now predict memory of an event before it even happens. A team at UCL (University College London) can now tell how well memory will serve us before we have seen what we will remember. view more (2006-02-27)
Researchers discover second depth-perception method in brain
It's common knowledge that humans and other animals are able to visually judge depth because we have two eyes and the brain compares the images from each. But we can also judge depth with only one eye, and scientists have been searching for how the brain accomplishes that feat. view more (2008-03-17)
Tumor suppressor gene in flies may provide insights for human brain tumors
In the fruit fly's developing brain, stem cells called neuroblasts normally divide to create one self-renewing neuroblast and one cell that has a different fate. But neuroblast growth can sometimes spin out of control and become a brain tumor. view more (2009-06-23)
The Human Brain: Detective of auditory and visual change
The human brain is capable of detecting the slightest visual and auditory changes. Whether it is the flash of a student's hand into the air or the faintest miscue of a flutist, the brain instantaneously and effortlessly perceives changes in our environment. view more (2008-01-21)
New Study Shows SARS Can Infect Brain Tissue
Severe acute respiratory syndrome (SARS), by its very name, indicates a disease of the respiratory tract. view more (2005-09-15)
Stress delays puberty
NWO research at Utrecht University has shown that when carp are subjected to stress, the development of their genital organs is delayed, so that they reach puberty later. It is likely that the stress hormone cortisol plays a major role in delaying puberty. Changes in water temperature produce stress in fish. Dimitri Consten of Utrecht University... view more...

Study finds significant differences in protocols hospitals use to determine brain death
A survey of some of the top hospitals in the country has found that protocols followed to determine brain death differ significantly among those institutions. view more (2008-01-18)
Commonly used drug may prevent fetal alcohol syndrome
Fetal alcohol syndrome (FAS) is often called the number one preventable birth defect. view more (2006-02-21)
Cellular cues identified for stroke recovery
When a stroke strikes, the supply of blood to the part of the brain affected is interrupted, starving it of oxygen. Brain cells can be seriously damaged or die, impairing local brain function. view more (2006-12-26)
How brain injury leads to seizures, memory problems
In a finding that may provide a scientific basis for eventual treatment, neurology researchers have shown that traumatic brain injury reduces the level of a protein that helps keep brain activity in balance. view more (2006-10-19)
Healing potential discovered in everyday human brain cells
University of Florida researchers have shown ordinary human brain cells may share the prized qualities of self-renewal and adaptability normally associated with stem cells. view more (2006-08-17)
New neuroimaging analysis technique identifies impact of Alzheimer's disease gene in healthy brains
Brain imaging can offer a window into risk for diseases such as Alzheimer's disease (AD). A study conducted at the University of Kansas School of Medicine demonstrated that genetic risk is expressed in the brains of even those who are healthy, but carry some risk for AD. view more (2009-11-18)
Clinical trial evaluating brain cancer vaccine is underway at NYU
A clinical trial evaluating a brain cancer vaccine in patients with newly diagnosed brain cancer has begun at NYU Medical Center. view more (2007-10-22)

Drug linked to increase in brain hemorrhage cases
The rate of brain hemorrhages associated with blood thinning drugs quintupled during the 1990s, according to a study published in the January 9, 2007, issue of Neurology, the scientific journal of the American Academy of Neurology. In people over age 80, the rate increased more than tenfold. view more (2007-01-09)
U of MN researchers identify new cord blood stem cell
Researchers at the University of Minnesota Medical School have discovered a new population of cells in human umbilical cord blood that have properties of primitive stem cells. view more (2006-02-14)
