Your Brain Can Get in the Way

So, how is your dorsolateral prefrontal cortex, or the DLPFC, as it is known to its friends, doing these days? What? You do not know what the DLPFC is? To be honest I didn’t either until about four days ago. I am reading the book Imagine: How Creativity Works by Jonah Lehrer. It runs through different models of how and why individuals and groups come up with new stuff, sometimes discussing the different areas of the brain integral to the process. That is where the DLPFC first came to my attention. Mr. Lehrer describes it as “a neural restraint system, a set of handcuffs the mind uses on itself.” If your DLPFC is fully functioning you will be less likely to swipe that candy bar from the convenience store or admit to your boss you haven’t actually accomplished anything of value since the Reagan administration or answer truthfully when your wife asks if her new dress makes her look fat. I bet if you wanted to you could spend a pretty entertaining day hanging out at Wal-Mart playing “Spot the person with a fully developed DLPFC” – hint there may be fewer than you expect. This part of the brain is one of the last sections to fully develop. This helps explain why kindergarten students are perfectly willing to invoke the death penalty if someone cuts in front of them in line. Even if it was a line leading to a lunch comprised entirely of cauliflower, lima beans and sawdust a kindergarten kid would scream bloody murder if another one budged in front of him. If the DLPFC is a mechanism of restraint why is it being discussed in a book about creativity? Isn’t creativity about pushing past restrictions to find the new and unusual? You are correct ma petite neurotransmitter. Mr. Lehrer cites a study where a scientist type person hooks a musician type person up to one of those brain camera thingees (he used different words but I’m not a scientist type person) and observes what happens when the musician is asked to do different tasks with his talent. If the music person is asked to play a memorized piece of music one set of brain structures becomes active, including the DLPFC, but if he is asked to improvise the DLPFC is actually deactivated. If you are going to be truly creative you have to take off the handcuffs. This is shown to be true of people improvising in different modes. Second City is an organization which, among other things, trains people to improvise. It is in Chicago, Toronto and Los Angeles and has produced dozens of world famous comedians from Alan Arkin to John Belushi to Tina Fey. One of the chief skills taught by the folks at Second City is the ability to not care what others think, not only to turn off the restraint mechanism of the brain but to beat it into a fine paste and serve it on a Triscuit to your mother-in-law. Okay, that analogy was a tad gross, but I am trying to push to new levels of creativity. Most often the natural state of adults is worrying, worrying about saying the wrong thing, worrying about being embarrassed, worrying about offending someone, worrying about that time in seventh grade when you had your first slow dance with a girl and the only words she said to you were “Boy, this is a long song.” Maybe that last one is just me (the song was How Deep is Your Love by the Bee Gees and it was a whole four minutes and five seconds – not that I ever really think about it). Once a Second City student has passed the worrying and embarrassed stage and become practiced at shutting down his DLPFC the next thing is to become automatic with the “yes, and” way of thinking. Improvisational comedy is most often a group exercise. In order to truly build a scene that works and makes people laugh things have to build on each other and DLPFC interference can kill the whole thing. So the students are taught the “yes, and” method. Everything that is proposed is instantly agreed to, the “yes” part, followed by something new the “and” part. Often in real life it would be great if people would agree and build upon rather than negate and tear down. I propose every politician go to improv classes. It might not actually fix the nation but it would be a stitch to see Harry Reid and Mitch McConnell pretend they were two girl scouts lost in a forest. Christopher Pyle would like to point out the difference between improv and improve is simply one letter. You can contact him at occasionallykeen@yahoo.com.
