Prefrontal-posterior coupling while observing the suffering of other people, and the development of intrusive memories.
Bottom Line: The factors contributing to why some people develop intrusive memories and others do not are still poorly understood.Individuals showing greater decreases of functional coupling between prefrontal and posterior cortices (greater decreases of EEG beta coherences) reported more intrusive memories of the witnessed events.The findings illuminate brain mechanisms involved in the encoding of information in ways that make intrusive memories more likely.

Mentions: For descriptive purposes, a topographic illustration of the highest correlations (sr > .20) between coherence changes of single electrode pairs and film-related intrusive memories over the week (IES-R intrusion scale) is given in Figure 5. As the present study follows a strictly hypothesis-driven approach, statistically evaluating theoretically motivated relations of only a few specific (aggregated) coherence data (Δcoh) to the variables referring to intrusive memories, no inferences are to be drawn from this purely descriptive illustration.
