Staring out of the window when you鈥檙e supposed to be working, you may find yourself daydreaming. But what鈥檚 actually going on inside the brain when you let your mind drift? Psychologists prefer to use the term 鈥渕ind-wandering鈥� for this activity, which fills up to half of our waking hours.

Claudia Hammond has spent the last two years working as part of Hubbub 鈥� a group including poets, historians and neuroscientists examining the topic of Rest at the Wellcome Collection. So is the brain ever truly at rest?

We all experience the world in different ways. By keeping a daydream diary Claudia discovers that she tends to mind-wander visually 鈥� often without words.

She also visits the Max Planck Institute in Leipzig where her brain is scanned by scientists who want to understand more about the surprisingly busy 鈥渞esting鈥� brain, seemingly on standby for whatever the day throws at us.

Brain scanners cannot yet detect what we are thinking. But monitoring the brains of trained meditators, one researcher claims to have pinpointed the part of the brain where mind-wandering starts 鈥� a region associated with memory. Activity then moves onto problem-solving regions 鈥� perhaps planning for the future by reflecting on the past.
