Scientists studied Sting’s brain—and here’s what they found

Earlier this year, 16-time Grammy Award-winner Sting was in Montreal for a concert. While he was there, he agreed to have his brain scanned by researchers who wanted to understand how he relates and classifies music.

To the average listener, certain songs might seem like they have nothing in common. But when Sting listened to two seemingly unrelated songs (like the Beatles’ “Girl” and Piazzola’s “Libertango”), brain scans unveiled the connections that Sting was able to hear, such as tempo, melodic motifs and what key the songs are in.

A paper about the research was published in “Neurocase.”

How Facebook Could Be Working Hand-in-Hand With Your Own Brain Chemistry

Social networksDid you know:

864 million people use Facebook on a daily basis? Or that the time spent on Facebook per user per day is more than twenty minutes?

What’s very interesting is that much of the success of Facebook can be attributed to brain chemistry.  The way Facebook is set up triggers the release of dopamine, a brain chemical that is linked to pleasurable feelings of reward, and also oxytocin, the “love hormone” that helps us feel close to people we care about.

One of the things about Facebook that releases the feel-good chemical dopamine in our brains is simply looking at pictures of attractive people.  And because these people are usually folks that we know and care about, it can also increase the release of oxytocin.

Introverts and Extroverts Have Different Brains

PrintMost people think of themselves as either an extrovert or an introvert, and they often think it has to do with how outgoing or shy they are.

And yet introversion and extroversion are actually based on where we get our energy. An easy way to tell if you’re an introvert or an extrovert is to answer this question: After a long week of work, which would you rather do: spend some quiet time alone OR go out with friends? The introverts among us would prefer some alone time, because lots of interaction can be physically and emotionally draining – introverts lose energy through human interaction and need alone time to recharge. Extroverts, on the other hand, gain energy from interacting with others, so at the end of a busy work week, they crave time with friends and loved ones to recharge.

Chocolate Improves Memory…In Snails!

iStock_000003537039_MediumIn the category of “weird news of the day,” it turns out that scientists have discovered a way to study the impact of dark chocolate on memory skills. But not the memory skills of humans, many of whom would crawl on all fours to be chosen to eat chocolate for the advancement of science. No, the participants selected for this particular study were actually snails.

Researcher submerged snails for 30 minutes in either regular water, or water containing epicatechin, a flavonoid found in cocoa. Whenever the snails extended their breathing tubes, researchers poked them with a stick. The lead study author, Ken Lukowiak, Ph.D, compared it to tapping a sleepy student on the nose every time he yawned in class—eventually the student would remember not to yawn. Would the snails do the same?

Hello? Can You Hear Me?

People who own smartphones often end up using their thumbs—a lot!—swiping through various touchscreens on an ongoing basis throughout the day.

All that thumb action can create physical changes in the brain, researchers say, leaving certain regions more active or even enlarged.

Scientists suspected this might be the case, since something similar happens to violinists. Regions of the brain associated with dexterity are larger in musicians who have played the violin for some time. Would smartphone thumbers show similar changes in brain activity?
