Ah, time to daydream. Here’s the latest from the WSJ:
In fact, our brain may be most actively engaged when our mind is wandering and we’ve actually lost track of our thoughts, a new brain-scanning study suggests. “Solving a problem with insight is fundamentally different from solving a problem analytically,” Dr. Kounios says. “There really are different brain mechanisms involved.”
By most measures, we spend about a third of our time daydreaming, yet our brain is unusually active during these seemingly idle moments. Left to its own devices, our brain activates several areas associated with complex problem solving, which researchers had previously assumed were dormant during daydreams. Moreover, it appears to be the only time these areas work in unison.
“People assumed that when your mind wandered it was empty,” says cognitive neuroscientist Kalina Christoff at the University of British Columbia in Vancouver, who reported the findings last month in the Proceedings of the National Academy of Sciences. As measured by brain activity, however, “mind wandering is a much more active state than we ever imagined, much more active than during reasoning with a complex problem.”
