Tobacco smoking impacts teens’ brains, UCLA study shows

Tobacco smoking is the leading preventable cause of death and disease in the U.S., with more than 400,000 deaths each year attributable to smoking or its consequences. And yet teens still smoke. Indeed, smoking usually begins in the teen years, and ...

Brain imaging provides window into consciousness

NEW YORK (Feb. 25, 2011) -- Using a sophisticated imaging test to probe for higher-level cognitive functioning in severely brain-injured patients provides a window into consciousness -- but the view it presents is one that is blurred in fascinating ...

Crying baby draws blunted response in depressed mom’s brain

EUGENE, Ore. -- Mothers who are depressed respond differently to their crying babies than do non-depressed moms. In fact, their reaction, according to brain scans at the University of Oregon, is much more muted than the robust brain activity in no...

Brain doesn’t need vision at all in order to ‘read’ material

Jerusalem, February 22, 2011 -- The portion of the brain responsible for visual reading doesn't require vision at all, according to a new study by researchers from the Hebrew University of Jerusalem and France. Brain imaging studies of blind ...

Chinks in the brain circuitry make some more vulnerable to anxiety

Why do some people fret over the most trivial matters while others remain calm in the face of calamity? Researchers at the University of California, Berkeley, have identified two different chinks in our brain circuitry that explain why some of us ar...

Exercise helps overweight children think better, do better in math

AUGUSTA, Ga. -- Regular exercise improves the ability of overweight, previously inactive children to think, plan and even do math, Georgia Health Sciences University researchers report. They hope the findings in 171 overweight 7- to 11-year-...

Brain scans predict likely success when it comes to quitting smoking

New research from University of Michigan says brain scans showing neural reactions can predict behavior change even better than the person whose brain is being scanned. Emily Falk, director of University of Michigan's Communication Neuroscience La...

Revealing the wiring that allows us to adapt to the unexpected

Milan, Italy, 31 January 2010 -- Wouldn't life be easy if everything happened as we anticipated? In reality, our brains are able to adapt to the unexpected using an inbuilt network that makes predictions about the world and monitors how those predi...

Study finds presence of peers heightens teens’ sensitivity to rewards of...

It is well known that teenagers take risks -- and that when they do, they like to have company. Teens are five times more likely to be in a car accident when in a group than when driving alone, and they are more likely to commit a crime in a grou...

Functional boost for magnetic resonance imaging

Over the last few years, researchers have used a type of brain scanning, known as functional magnetic resonance imaging fMRI, to help them map changes in blood flow in the brain and to correlate this with thoughts and behavior. A new way to analyze ...
