Mind-wandering or daydreaming is one of the most common activities that happen in a day. It is almost impossible to not eventually have your mind wander off into thoughts about the past or fantasies about the future. In this episode, I interview Dr Julia Kam on her research into mind-wandering and how we can study the major network involved, the default mode network. We talk about what the default mode network does, how we can study it and where the limits of the field are with such a newly studied network.
