FMRI Brain Scans Show That Sleep Deprivation Can Lead To Higher Anticipatory Anxiety

New research shows that sleep loss markedly exaggerates the degree to which we anticipate impending emotional events, particularly among highly anxious people, who are especially vulnerable. Two common features of anxiety disorders are sleep loss and an amplification of emotional response. Results from the new study suggest that these features may not be independent of […]

Maltreated Children Show Same Pattern Of Brain Activity As Combat Soldiers

Children exposed to family violence show the same pattern of activity in their brains as soldiers exposed to combat, new research has shown. In the first functional MRI brain scan study to investigate the impact of physical abuse and domestic violence on children, scientists at UCL in collaboration with the Anna Freud Centre, found that […]

Violent Games Can Emotionally Desensitize Players To Aggressive Behavior

After excessively violent events, shoot ’em up games regularly come under scrutiny. In Norway, several first-person shooter games actually disappeared from the market for a while after the killings. Does intense fighting on a flat screen display also result in aggressive behavior in real life? Researchers from the University of Bonn found brain activity patterns […]

Scientists Use ‘Optogenetics’ To Control Reward-Seeking Behavior

Using a combination of genetic engineering and laser technology, researchers at the University of North Carolina at Chapel Hill have manipulated brain wiring responsible for reward-seeking behaviors, such as drug addiction. The work, conducted in rodent models, is the first to directly demonstrate the role of these specific connections in controlling behavior. The findings are […]

Negative Emotion May Enhance Memory

Picture a menacing drill sergeant, a gory slaughterhouse, a devastating scene of a natural disaster. Researchers at Washington University in St. Louis have found that viewing such emotion-laden images immediately after taking a test actually enhances people’s retention of the tested material. The data the researchers gathered in recent studies are the first to show […]

Maturing Brain Circuitry Changes Play A Role In Moral Sensitivity

People’s moral responses to similar situations change as they age, according to a new study at the University of Chicago that combined brain scanning, eye-tracking, and behavioral measures to understand how the brain responds to morally laden scenarios. Both preschool children and adults distinguish between damage done either intentionally or accidently when assessing whether a […]
