Common wisdom tells us that for a successful relationship partners shouldn't go to bed angry. But new research from a psychologist at Harvard University suggests that brain activity—specifically in the region called the lateral prefrontal cortex—is a far better indicator of how someone will feel in the days following a fight with his or her partner.
Individuals who show more neural activity in the lateral prefrontal cortex are less likely to be upset the day after fighting with partners, according to a study in this month's Biological Psychiatry. The findings point to the lateral prefrontal cortex's role in emotion regulation, and suggest that improved function within this region may also improve day-to-day mood.
"What we found, as you might expect, was that everybody felt badly on the day of the conflict with their partners," says lead author Christine Hooker, assistant professor of psychology in Harvard's Faculty of Arts and Sciences. "But the day after, people who had high lateral prefrontal cortex activity felt better and the people who had low lateral prefrontal cortex activity continued to feel badly."
Hooker's co-authors are Özlem Ayduk, Anett Gyurak, Sara Verosky, and Asako Miyakawa, all of the University of California at Berkeley.
Research has previously shown that the lateral prefrontal cortex is associated with emotion regulation in laboratory tests, but the effect has never been proven to be connected to experiences in day-to-day life.
This study involved healthy couples in a relationship for longer than three months. While in an fMRI scanner, participants viewed pictures of their partners with positive, negative, or neutral facial expressions and their neural activity was recorded while reacting to the images. While in the lab, participants were also tested for their broader cognitive control skills, such as their ability to control impulses and the shift and focus of attention.
For three weeks, the couples also recorded in an online diary their daily emotional state and whether they had had a fight with their partners.
Hooker found that participants who displayed greater activity in their lateral prefrontal cortex while viewing their partners' negative facial expressions in the scanner were less likely to report a negative mood the day after a fight with their partners, indicating that they were better able to emotionally "bounce back" after the conflict.
She also found that those who had more activity in the lateral prefrontal cortex and greater emotional regulation after a fight displayed more cognitive control in laboratory tests, indicating a link between emotion regulation and broader cognitive control skills.
"The key factor is that the brain activity in the scanner predicted their experience in life," says Hooker. "Scientists believe that what we are looking at in the scanner has relevance to daily life, but obviously we don't live our lives in a scanner. If we can connect what we see in the scanner to somebody's day-to-day emotion-regulation capacity, it could help psychologists predict how well people will respond to stressful events in their lives."
While Hooker acknowledges that more work must be done to develop clinical applications for the research, it may be that lateral prefrontal cortex function provides information about a person's vulnerability to develop mood problems after a stressful event. This raises the question as to whether increasing lateral prefrontal cortex function will improve emotion regulation capacity.
The research was funded by the National Institute for Mental Health and the National Alliance for Research in Schizophrenia and Depression.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
