In Sync: How Our Brain Waves Affect Each Other

Christine Chen

Most of us have, at some point, felt in sync with a friend or a family member because of a shared experience or shared perspectives. Not only can this “feeling” be measured in oscillation patterns of electrical signals—brain waves— that occur when brain cells communicate with each other, but brain-scanning studies revealed that human brain wave patterns do synchronize in an interactive group of people.

In one such study, researchers had a group of students wear portable electroencephalogram (EEG) headsets to measure changes in their brain wave patterns for the duration of a biology course at a New York high school. Brain waves known as beta bands started synchronizing among the subjects as they were learning. When the students’ brain waves were in sync with one another, the students became more engaged with the class and gave positive feedback about the course and the teacher.

What this study suggests is the mutual benefit of interacting with one another one-on-one or as a team: syncing our brain waves can help improve collaboration and advance a mutual goal. So let’s sync!
