The brain's motivation station
The prospect of a paycheck, good grade, or promotion wonderfully concentrates the mind, and researchers have now identified the brain circuitry responsible for such reward-motivated learning. view more (2006-05-04)
Reward-stress link points to new targets for treating addiction
Rewarding and stressful signals don't seem to have much in common. But researchers studying diseases ranging from drug addiction to anxiety disorders are finding that the brain's reward and stress signaling circuits are intertwined in complex ways. view more (2008-12-17)
CSHL-led team discovers rare mutation dramatically increasing schizophrenia risk
An international team of researchers led by geneticist Jonathan Sebat, Ph.D., of Cold Spring Harbor Laboratory (CSHL), has identified a mutation on human chromosome 16 that substantially increases risk for schizophrenia. view more (2009-10-26)
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)
Cocaine-linked genes enhance behavioral effects of addiction
New research sheds light on how cocaine regulates gene expression in a crucial reward region of the brain to elicit long-lasting changes in behavior. view more (2009-05-14)
Post brain injury: New nerve cells originate from neural stem cells
Most cells in the human brain are not nerve cells, but supporting cells (glial cells). They serve as a framework for nerve cells and play an important role in the wound reaction that occurs with injuries to the brain. view more (2008-03-12)
Chilean authors, publishing in Science, discover drug-craving brain region in rats
Chilean researchers have identified a region of the brain - the insular cortex - that plays a role in drug craving in amphetamine-addicted rats, according to a report published in the 26 October issue of the journal Science, published by the American Association for the Advancement of Science (AAAS), the nonprofit science society. view more (2007-10-26)
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)
MIT: Long-distance brain waves focus attention
Just as our world buzzes with distractions - from phone calls to e-mails to tweets - the neurons in our brain are bombarded with messages. view more (2009-05-29)
Aging brains allow negative memories to fade
It turns out there's a scientific reason why older people tend to see the past through rose-coloured glasses. A University of Alberta medical researcher, in collaboration with colleagues at Duke University, identified brain activity that causes older adults to remember fewer negative events than their younger counterparts. view more (2008-12-17)
Brain reacts to fairness as it does to money and chocolate
The human brain responds to being treated fairly the same way it responds to winning money and eating chocolate, UCLA scientists report. Being treated fairly turns on the brain's reward circuitry. view more (2008-04-22)
Human Brain Connectivity Mapping
The unique connectivity pattern of a brain region determines the type of information available to it, and hence influences its function. Defining these patterns enhances our knowledge of human brain architecture and function. Non-invasive in vivo definition of brain connectivity patterns complements functional imaging and provides new... view more... (2004-09-23)
Sights and sounds of emotion trigger big brain responses
Researchers at the University of York have identified a part of the brain that responds to both facial and vocal expressions of emotion. view more (2009-11-03)
Sensitivity of brain center for 'sound space' defined
While the visual regions of the brain have been intensively mapped, many important regions for auditory processing remain "uncharted territory." Now, researchers at the Hebrew University of Jerusalem and elsewhere have identified a region responsible for a key auditory process - perceiving "sound space," the location of sounds,... view more...

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)
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)
Low birth weight babies with reduced occipital regional volumes at higher risk for visual impairment
Preterm infants with smaller occipital brain volumes are more likely to experience impaired visual function in early childhood according to a study published in the August 2006 issue of Investigative Ophthalmology & Visual Science (IOVS). view more (2006-08-30)
Quicker and easier rehabilitation following a stroke
By artificially vibrating certain muscle parts, the brain areas and neuronal pathways responsible for movement can be trained. This has the potential to help stroke patients recover their mobility more quickly. These are the results of PhD research by Maarten Steyvers of the Department of Kinesiology, K.U.Leuven. view more (2004-06-11)
Introduced marine species get larger in the invaded region
The transport of species outside their native region through human activities has often had a dramatic impact on the ecosystems into which these species are introduced and on the surrounding economies. The consequences of introduction for the introduced species itself, including changes in body size and shape, are less recognized. Prior studies of... view more... (2003-08-13)
New research shows how aging brain brings a healthy dose of perspective
A University of Alberta researcher in collaboration with researchers from Duke University has proven that wisdom really does come with age, at least when it comes to your emotions. view more (2008-06-13)
