In most cases, brain activity measured by functional magnetic resonance imaging (MRI) is used to study risk-taking tendencies. This study is one of a few articles that reported a correlation between tissue structure and human behavior. The authors believe that analyzing the brain structure through its stiffness can provide a more complete understanding of how physiology affects behavior. In addition, this technique could be used as an indicator of those adolescents who are more prone to real world risky activities and a useful measure for characterizing response to intervention.
