Anxiety Cues Found in the Brain Despite Safe Environment

Virtual reality is helping researchers uncover some of the secrets of anxiety. Using VR, study participants were able to distinguish between safe and dangerous environments in a game. However, brain scans of those with anxiety showed increased activity in the insula and dorsomedial prefrontal cortex while in a safe zone, indicating their brains were associating the safe environment with threat or danger.
