Summary: Emotional regulation was linked to theta wave activity in the frontal cortex of the brain.

Now Inès Zouaoui, a master’s student in psychology supervised by Professor Marc Lavoie at the Research Center of the Montreal Mental Health University Institute, has demonstrated that emotional regulation is associated with the action of theta waves in a specific part of the brain, the frontal cortex.

A brain wave specific to emotional regulation.

Building on the results of a 2013 study that showed theta waves are generated during emotional regulation, the Montreal research team gave 24 subjects a cognitive reappraisal exercise.

“We performed more detailed analyses of the encephalograms than what was done in the previous study to measure the frequencies of the brain waves generated during cognitive reappraisal and found only theta waves, which oscillate between 4 and 8 Hz,” Zouaoui reported.

“So theta waves can be considered a marker of emotional regulation.

“What’s new about our study is that by comparing the emotional induction and emotional regulation phases, we were able to show that theta waves are specific to the regulation phase,” said Zouaoui.

“We also looked for alpha waves, which are in the 8 to 13 Hz range, to see if theta waves are specific to emotional regulation and found that alpha waves are not sensitive to either emotional induction or emotional regulation.”

“Since theta waves can be a marker of successful emotional regulation, this could lead to new treatment options for people whose emotional regulation process is perturbed, which is the case in severe anxiety and schizophrenia, for example.”
