The prefrontal cortex of the brain can not only be used in emotional responses, but also helps controls dopamine, serotonin, and norepinephrine-the three neurotransmitters vital to mood regulation. The Lateral Prefrontal Complex (LPFC) helps us to find a way of behaving by letting the body assess various alternatives mentally. A new study theorizes that the LPFC can help control their emotional reactions to negative facial expressions from their spouses and help predict emotional resiliency.
The activity in the lateral prefrontal cortex can be important to daily emotional "bounce back" and improving this brain area can help improve daily mood. The study found that those who had more neural activity in the LPFC were less likely to be mad the day after fighting with a partner. Obviously, everybody felt bad the day of the conflict. However, those with high LPFC activity felt badly the day after compared to those with low activity.
The study was done using healthy couples who have been in a relationship for more than 3 months to look at pictures of their partners with neutral, positive, or negative expressions while their brain activity was recorded. In the laboratory, the participants tested out their broader cognitive control skills like impulse control.
