Your Brain On Rhythm

People tend to gravitate towards anything with rhythm. Whether it’s dancing, singing, or listening to music, rhythm governs the way we move and can even positively affect our moods. Let’s take a closer look at the science behind rhythm and it affects our brains.

A Rhythmic Study

Three different studies that explain it to us how rhythm affects our brain and functions. The first study explored the idea that music can naturally calm us down. Patients about to undergo surgery were separated into two groups: those who listened to music and those who took anti-anxiety medication.

They found that those who listened to music had lower self-report anxiety and lower levels of the stress hormone cortisol, as well as active immunoglobin A (an antibody linked to immunity), and a higher count of germ and bacteria-fighting cells.

What makes rhythm so enjoyable?

The second study had participants listen and rate 60 excerpts of music while in an fMRI machine to keep an eye on the brain activity. They found higher activity in the nucleus accumbens when the participant liked the music, meaning “reward-related expectations were met or surpassed.” In other words, the brain registered a reward associated with that clip of music.

They also found that the superior temporal gyrus forms based on past experiences with music, and tastes reflect that. So an individual growing up listening to jazz will have a differently formed superior temporal gyrus, and therefore, a higher appreciation for jazz, than someone who grows up listening to punk rock.

The Benefits of Music

Actually, the final study proves that we all experience music pretty much the same way. Participants, again, while in an fMRI, listened to four symphonies by William Boyce. The researchers found that the brains all reacted pretty much the same way: eliciting movement, attention, planning, and memory.

It is also suggested that this common experience is what unifies people. “It’s not our natural tendency to thrust ourselves into a crowd of 20,000 people, but for a Must concert or a Radiohead concert, we’ll do it,” said Daniel Levitin, a psychologist studying neuroscience and music at McGill University.

Now you know a bit more about why we love music and dancing so much. If you’re ever undergoing an MRI at our center, be sure to bring in your tunes to make the time fly by during your scan.
