A team of researchers from Massachusetts General Hospital (MGH) has used brain imaging, genetics and experimental psychology techniques to identify a connection between brain reward circuitry, a behavioral measurement of preference and a gene variant that appears to influence both.

MIT unlocks mystery behind brain imaging

In work that solves a long-standing mystery in neuroscience, researchers at MIT's Picower Institute for Learning and Memory have shown for the first time that star-shaped brain cells called astrocytes—previously considered bit players by most neuroscientists—make noninvasive brain scans possible.

Improving anxiety treatment through help of brain imaging

Wouldn’t it be nice if our doctors could predict accurately whether we would respond to a particular medication" This question is important because research studies provide information about how groups of patients tend to respond to treatments, but inevitably, differences among groups of patients with the same diagnosis mean that findings about groups of patients may not apply to individuals from those groups.

Scientists explore brain's reaction to potent hallucinogen

Brain-imaging studies performed in animals at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory provide researchers with clues about why an increasingly popular recreational drug that causes hallucinations and motor-function impairment in humans is abused.

Biologists have just confirmed what poets have known for centuries: eyes really are windows of the soul—or at least of the brain. In a new study published in the April 2008 print issue of The FASEB Journal, Harvard researchers describe the development of gene probe eye drops that—for the first time—make it possible to monitor and detect tissue repair in the brain of living organisms using MRI.

Introspective experiences inform inferences about similar people

Using fMRI scanning, researchers have found that the region of the brain associated with introspective thought is also accessed when inferring the thoughts of other people who are similar to oneself. However, this is not the case when considering those who are different politically, socially, or religiously.

High-tech interrogations may promote abuse

There is evidence that brain imaging technology is being used to interrogate suspected terrorists despite concerns that it may not be reliable, and that it might inadvertently promote abuse of detainees, according to a Penn State researcher.

Myth of runner's high revisited with brain imaging

Throughout the world, amateurs, experts and the media agree that prolonged jogging raises people's spirits. And many believe that the body’s own opioids, so called endorphins, are the cause of this. But in fact this has never been proved until now. Researchers at the Technische Universitet Munchen and the University of Bonn succeeded to demonstrate the existence of an ‘endorphin driven runner’s high’.

Culture influences brain function

People from different cultures use their brains differently to solve the same visual perceptual tasks, MIT researchers and colleagues report in the first brain imaging study of its kind.

Where thoughts of familiar objects occur inside human brain

A team of Carnegie Mellon University computer scientists and cognitive neuroscientists, combining methods of machine learning and brain imaging, have found a way to identify where people’s thoughts and perceptions of familiar objects originate in the brain by identifying the patterns of brain activity associated with the objects.

Brain matures few years late in ADHD, but follows normal pattern

In youth with attention deficit hyperactivity disorder (ADHD), the brain matures in a normal pattern but is delayed three years in some regions, on average, compared to youth without the disorder, an imaging study by researchers at the National Institutes of Health’s (NIH) National Institute of Mental Health (NIMH) has revealed.

Brain Imaging Aids in Defense against Genetic Disease

Children born with a rare genetic disorder that can lead to debilitating and irreversible brain injury may find protection with the aid of brain imaging and a modified diet.
