This is your brain on boredom
Researchers used EEG caps to measure the brain activity of people when they were bored. Originally, the team believed that people who react negatively to boredom were hardwired differently, but the research showed otherwise. The scientists determined that at baseline, there was no difference between the brains of people who react negatively to boredom and those who experience no ill effects from it. The difference in brain waves only appeared once the state of boredom was initiated.
