Watching Own Brain Activity in Real-Time Helps Avoiding Bad Thoughts, Say Yale Researchers
Real-time brain scan readouts apparently enable people to train their own brain and avoid harmful thoughts, especially the type that activates abnormal hyperactivity leading to anxiety. Displaying the activity in specific regions of their brains allows individuals to learn to control that activity and lessen their anxiety, say Yale researchers.
The researchers, who published their findings online in the journal Translational Psychiatry, report that through a process of trial and error, these subjects were gradually able to learn to control their brain activity. This led both to changes in brain connectivity and to increased control over anxiety. These changes were still present several days after the training.
Extreme anxiety associated with worries about dirt and germs is characteristic of many patients with obsessive-compulsive disorder (OCD). Hyperactivity in the orbitofrontal cortex is seen in many of these individuals.
fMRI-driven neurofeedback has been used before in a few contexts, but not for the treatment of anxiety, the researchers say. The findings raise the possibility that real-time fMRI feedback may provide a novel and effective form of treatment for OCD.
