A scientist at the University of York has found that part of the brain used for daydreaming also helps us to do things "on autopilot".
Deniz Vatansever, a research associate in the department of psychology, has found the so-called ‘default mode network’ could be vital in helping people perform routine tasks.
His studies have shown this part of the brain is what enables anyone to do something they are familiar with, without needing to think their way through the action.
Dr Vatansever found this out while working on his PhD. It could help in the treatment of brain disorders and mental health conditions.
