Brain's problem-solving function at work when we daydream
Date:5/11/2009

A new University of British Columbia study finds that our brains are much more active when we daydream than previously thought.

The study, published in the Proceedings of the National Academy of Sciences, finds that activity in numerous brain regions increases when our minds wander. It also finds that brain areas associated with complex problem-solving previously thought to go dormant when we daydream are in fact highly active during these episodes.

"Mind wandering is typically associated with negative things like laziness or inattentiveness," says lead author, Prof. Kalina Christoff, UBC Dept. of Psychology. "But this study shows our brains are very active when we daydream much more active than when we focus on routine tasks."

For the study, subjects were placed inside an fMRI scanner, where they performed the simple routine task of pushing a button when numbers appear on a screen. The researchers tracked subjects' attentiveness moment-to-moment through brain scans, subjective reports from subjects and by tracking their performance on the task.

The findings suggest that daydreaming which can occupy as much as one third of our waking lives is an important cognitive state where we may unconsciously turn our attention from immediate tasks to sort through important problems in our lives.

Until now, the brain's "default network" which is linked to easy, routine mental activity and includes the medial prefrontal cortex (PFC), the posterior cingulate cortex and the temporoparietal junction was the only part of the brain thought to be active when our minds wander.

However, the study finds that the brain's "executive network" associated with high-level, complex problem-solving and including the lateral PFC and the dorsal anterior cingulate cortex also becomes activated when we daydream.

"This is a surprising finding, that these two brain networks are activated in parallel," says Ch
