At this point, scientists know that rapid eye movement (REM) sleep helps humans consolidate their emotional memories. The current study helped to understand that silence is also a powerful tool. In the series of experiments with sleeping and awake mice, researchers found that the quieting of the prefrontal cortex during REM sleep helps the whole system reset.

The research team concluded that without proper REM sleep, networks in the brain can become 'oversaturated' with emotional messages, like fear, making it harder to determine important signals from background noise noticing that it can lead a mouse to act overly fearful or not fearful enough when they're awake.
