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)
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)
Competition May Be Reason For Bigger Brain
For the past 2 million years, the size of the human brain has tripled, growing much faster than other mammals. Examining the reasons for human brain expansion, University of Missouri researchers studied three common hypotheses for brain growth: climate change, ecological demands and social competition. view more (2009-06-23)
Transcendental Meditation reduces the brain's reaction to pain
Twelve healthy long-term meditators who had been practicing Transcendental Meditation for 30 years showed a 40-50% lower brain response to pain compared to 12 healthy controls. view more (2006-08-10)
Cancer researchers confirm brain tumor genetic subtype informs treatment, predicts outcome
Research confirms that determining the genetic composition of brain cancers can better inform doctors and patients for treatment options and prognosis. The findings could change the future of how cancers are diagnosed. view more (2006-07-07)
A Window into the Brain
When we absorb new information, the human brain reshapes itself to store this newfound knowledge. But where exactly is the new knowledge kept, and how does that capacity to adapt reflect our risk for Alzheimer's disease and other forms of senile dementia later in our lives? view more (2009-08-13)
Tracking the memory trace
Memory formation follows a dynamic pattern, allowing for retrieval from different areas of the brain, depending on when an organism needs to remember, said a researcher at Baylor College of Medicine. view more (2005-12-05)
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)
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...

Complexity constrains evolution of human brain genes
Despite the explosive growth in size and complexity of the human brain, the pace of evolutionary change among the thousands of genes expressed in brain tissue has actually slowed since the split, millions of years ago, between human and chimpanzee. view more (2006-12-26)
Color contrast is 'seen' by the brain early doors
Colour contrast is detected much earlier in the brain than previously thought, a new study shows. view more (2007-09-10)
Can mental training games help prevent Alzheimer's?
Loss of thinking power is a fear shared by many aging baby boomers. That fear has resulted in a budding industry for brain training products - exercises such as Brain Age, Mindfit and My Brain Trainer - which in 2007 generated $80 million in the United States alone. view more (2009-03-11)
Parts of brain involved in social cognition may be in place by age 6
Social cognition-the ability to think about the minds and mental states of others-is essential for human beings. In the last decade, a group of regions has been discovered in the human brain that are specifically used for social cognition. view more (2009-07-15)
Barrow researchers identify a new approach to detect the early progression of brain tumors
Researchers at Barrow Neurological Institute at St. Joseph's Hospital and Medical Center recently participated in a pilot study with the Montreal Neurological Institute that suggests a certain type of MRI scanning can detect when a patient is failing brain tumor treatment before symptoms appear. view more (2008-08-29)
Epilepsy and brain pathology linked together by the protein ADK
The brain of individuals who suffer from epilepsy is characterized by astrogliosis, a brain pathology evidenced by a complex series of changes in the morphology and function of brain cells known as astrocytes. view more (2008-01-03)
Internal choices are weaker than those dictated by the outside world
The underlying sense of being in control of our own actions is challenged by new research from UCL (University College London) which demonstrates that the choices we make internally are weak and easily overridden compared to when we are told which choice to make. view more (2009-02-11)
Brain's center for perceiving 3-D motion is identified
Ducking a punch or a thrown spear calls for the power of the human brain to process 3-D motion, and to perceive an object (whether it's offensive or not) moving in three dimensions is critical to survival. It also leads to a lot of fun at 3-D movies. view more (2009-07-21)
Scans show learning 'sculpts' the brain's connections
Spontaneous brain activity formerly thought to be "white noise" measurably changes after a person learns a new task, researchers at Washington University School of Medicine in St. Louis and the University of Chieti, Italy, have shown. view more (2009-10-09)
Proteins in urine predict brain damage in laboratory animals
The study dealt with the development and prevention of strokes in particular rats which had spontaneously developed extremely high blood pressure. Such a high blood pressure level leads within a few weeks to damage to the kidneys, heart and brain such that the rats die. The researchers found that brain damage in these rats is always preceded by... view more... (1999-06-21)
Chronic pain harms the brain
People with unrelenting pain don't only suffer from the non-stop sensation of throbbing pain. They also have trouble sleeping, are often depressed, anxious and even have difficulty making simple decisions. view more (2008-02-06)
