Adolescents at risk of developing a substance-use disorder have deficits in frontal brain activation

Children and adolescents at high risk for developing a substance-use disorder (SUD) tend to show deficits in executive cognitive function (ECF). A study using functional magnetic resonance imaging (fMRI) to assess eye movements in adolescents has found a link between brain functioning and risk for developing an SUD.

Researchers use MRI to study spontaneity, creativity

A pair of Johns Hopkins and government scientists have discovered that when jazz musicians improvise, their brains turn off areas linked to self-censoring and inhibition, and turn on those that let self-expression flow.

Brain activity linked to the parental instinct

Why do we almost instinctively treat babies as special, protecting them and enabling them to survive" Darwin originally pointed out that there is something about infants which prompts adults to respond to and care for them which allows our species to survive.

Video games activate reward regions of brain in men more than women

Allan Reiss, MD, and his colleagues have a pretty good idea why your husband or boyfriend can't put down the Halo 3. In a first-of-its-kind imaging study, the Stanford University School of Medicine researchers have shown that the part of the brain that generates rewarding feelings is more activated in men than women during video-game play.

Brain imaging and genetic studies link thinking patterns to addiction

Scientists have for the first time identified brain sites that fire up more when people make impulsive decisions. In a study comparing brain activity of sober alcoholics and non-addicted people making financial decisions, the group of sober alcoholics showed significantly more "impulsive" neural activity.

Sleepless nights may trigger primitive mind: study

Researchers say a few nights without sleep can not only make people tired and emotional, but may actually put the brain into a primitive "fight or flight" state.

Brain measurements could lead to better devices to move injured or artificial limbs

Neuroscientists at the Hebrew University of Jerusalem have developed a novel approach for measuring and deciphering brain activity that holds out promise of providing improved movements of natural or artificial limbs by those who have been injured or paralyzed.

Abstinent alcoholics can have reduced brain activation

Heavy alcohol use can lead to structural and functional changes in the brain.
New findings show that even when structural damage may not be apparent, brain activation can still be reduced.
Researchers refer to this alcohol-induced damage as “latent lesions.”

Clinical depression linked to abnormal emotional brain circuits

In what may be the first study to use brain imaging to look at the neural circuits involved in emotional control in patients with depression, researchers at the University of Wisconsin-Madison have found that brains of people with clinical depression react very differently than those of healthy people when trying to cope with negative situations.

Vision restoration therapy shown to improve brain activity

Columbia University Medical Center researchers have demonstrated using functional magnetic resonance imaging (fMRI), that brain activity was increased in stroke and traumatic brain injury survivors who underwent Vision Restoration Therapy (VRT), a rehabilitative treatment that helps these patients recover lost vision.
