Summary:

- The study found that witnessing a traumatic event can lead to PTSD-like symptoms in the brain, even in individuals who were not directly involved in the event.
- Researchers used functional MRI scans to analyze the brain activity of bystanders who witnessed a traumatic event, and found increased activity in brain regions associated with PTSD, such as the amygdala and prefrontal cortex.
- The findings suggest that even indirect exposure to trauma can have significant psychological and neurological impacts, highlighting the importance of providing support and resources for bystanders and witnesses of traumatic events.
