Watching Your Brain Freak Out On A Scanner Calms You Down

RATE THIS! +9

In a quirky new experiment, researchers at Yale University found that simply showing people what their anxious brains look like was enough to help those subjects lessen their anxiety.

 

The participants in the study even learned how to control activity in a certain brain region after just two sessions of watching real-time brain imaging feedback.


The scientists first recruited 23 people who reported having anxiety about germs and contamination. Then, they had the subjects come into the lab for four visits. During the first session, all of the subjects underwent functional magnetic resonance imaging (fMRI) while they looked at neutral images and images designed to trigger worries about germs. The researchers looked at a specific area of the brain called the orbitofrontal cortex, a region that has previously been linked to contamination anxiety.


During the second and third visits, the participants first looked at contamination-related pictures and were told to try to minimize their worries. They ranked their anxiety on a scale from 1 to 5 for each image. Then, 12 of the subjects spent 90 minutes hooked up to an fMRI machine, during which time they viewed germ-y images alongside a real-time line-graph of activity in their orbitofrontal cortex.
Using strategies the researchers had taught them, the participants tried to control their brain activity and observed how the brain-activity readout changed. (The other 11 subjects served as the control group; instead of seeing their own real-time brain activity, they watched recordings of readouts from previous sessions.)


At the final visit, the subjects again looked at triggering pictures and ranked how anxious they felt. They also underwent another brain scan that looked for changes in connectivity in brain regions associated with emotion regulation and cognitive control.
