Brain-Activity Data Clarify Contradictions In Earlier Anxiety Research

CHAMPAIGN, Ill. -- Psychologists need not worry about years of confusing research regarding anxiety. With emotional response broken into two aspects -- worry and panic -- a distinct pattern of activity arises in the brain, researchers say.

The new findings, reported by University of Illinois researchers, show that panic attacks, or excessive psychophysiological arousal, are reflected in people who worry by increased electrical activity in the right posterior of the brain during times of environmental stress. While at rest, worriers in the study showed more activity in the left frontal section of the brain.

As a result of the findings in this study -- reported in the August issue of the Journal of Abnormal Psychology -- and subsequent work, the researchers have begun a project measuring brain activity in combat veterans suffering from post-traumatic stress syndrome.

In the study, 40 students were split into groups based on levels of reported trait anxiety, which is associated with a tendency toward anxious arousal and panic. As the students listened to narratives that depicted pleasant, unpleasant, arousing or non-arousing events, researchers measured brain activity.

Previous research on anxiety has yielded often contradicting and unexplainable results, with electrical activity fluctuating between the brain's left and right hemispheres. The new findings, said U. of I. psychologist Wendy Heller, may clear up the confusion.

"Worry seems to be associated more with verbal ruminating, obsessing or making up stories in your head," she said. "Panic is much more a physiological state of alertness in which a person responds to a perceived threat with heart pounding, hands sweating, light-headedness and/or dizziness.

"It's been right there in the literature. Most of the studies that found more right-hemisphere activity were looking at panic or some kind of stressful state," she said. "Most of the studies that found more
