Theta and Delta changes in resting-state EEG activity after regulating emotions

One intriguing but still unexplored question is whether regulating emotions can leave a trace in the brain by affecting its oscillatory activity. To address this issue, electrical brain activity at rest was recorded before and after deploying an emotion regulation strategy, namely distancing. A significant increase in theta and delta activity after the regulation session emerged, suggesting that regulating emotions can alter brain activity at rest. This is not only of great interest for affective neuroscience, but may also be helpful for clinical applications.
