The neural basis of Mind Wandering
We all experience moments of inattention when, seemingly, our mind has wandered to a different place entirely. We have "tuned out" of our current activity, we are "day-dreaming", experiencing an "attentional lapse" or, as scientific folk likes to call it, are engaging in "task-unrelated thoughts". But what happens in our brain during these periods of inattention? Are we always aware that we are actually dreaming with open eyes?
In our study of this phenomenon, we make use of a wide variety of techniques and tools. We use functional magnetic resonance imaging (fMRI) to map the networks in the brain that are related to periods of inattention. In a recent study (Mittner et al, 2014), we found that communication within and between resting-state networks (groups of brain regions that are consistenly activated during periods of rest) plays a key role in this. We also apply the electroencephalogram (EEG) and pupillometry to get further insights into the involved neural mechanisms.
This figure shows how we integrate different measures to detect and analyse periods of mind wandering. Using such an approach, we could actually achieve a detection rate of close to 80%.
