The Brainwaves That Boost Creativity

Daily brief research updates from the cognitive sciences

I outlined here how recent research has shown that the brains of highly creative individuals use different networks, and this also reminded me of separate piece of research from a few years ago that shows that creative brains have intriguing brain wave patterns.

In this study researchers around Caroline Di Bernardi Luft of the Queen Mary University of London found different brainwave patterns during creative thinking tasks in those who were more successful in these tasks.

What they found is that those who came up with more ideas in a creative thinking task “how many uses can you think of for a brick” or more distant relationships in associative chains e.g.  cat > dog > animal > pet > human > people > family.

So what was happening in the brain?

Well first off it is known that when doing these tasks that obvious associations are the ones that jump to mind first. The brain is designed to build associations. In the case of the brick the most obvious is to build a wall or house. But creative people seem to suppress the obvious ideas searching and enabling more creative solutions.

And indeed, the researchers found that certain brainwaves, specifically alpha oscillations, in the right temporal area of the brain, increase when individuals need to suppress obvious or misleading associations in different creative tasks.

So, it seems that alpha brain waves in this part of the brain help creatives to suppress ideas. But is this just an association or does this actively help?

The researchers then looked to see if this was indeed causal. To do this they activated study participants brains while doing tasks with a technique called transcranial magnetic stimulation. This delivers a weak and safe electrical current to the brain and can stimulate various regions at various intensities.

And yes, when triggering alpha waves in the right temporal lobe participants could suppress the obvious ideas better.

So, one route to being creative is to suppress the obvious ideas that jump to mind. This is also triggered by brain waves patterns in the brain. But the good thing about this is that this can be actively trained though practising suppression or potential through neurofeedback techniques (structured brain wave training).

And that leaves me here trying to think of a non-obvious ending to this article.
