The neural model of stress vulnerability involves overreaction in areas involved in threat detection and fear response, such as the amygdala, insula, and dorsal cingulate cortex (dACC)

The study collected functional MRI (fMRI) scans of civilian trauma survivors in different areas 2 weeks after the trauma
In further research on post-traumatic recovery, functional MRI scans of trauma survivors in threat, suppression, and reward tasks
In further research on post-traumatic recovery, functional MRI scans of trauma survivors in threat, suppression, and reward tasksParticipants reported psychopathological symptoms in the first 6 months after trauma through a mobile survey
In the discovery group (N=69) and the replication group (N=77), functional MRI (fMRI) of trauma survivors showed four clusters
In the discovery group (N=69) and the replication group (N=77), functional MRI (fMRI) of trauma survivors showed four clusters
Two weeks after a motor vehicle collision, task-based functional MRI identified 4 groups of individuals based on neural activity characteristics reflecting threat response, reward response, and inhibitory participation
When trauma survivors perform threats, rewards, and suppression tasks, the whole brains of the four groups are compared
