London, Dec 11 : While carrying out boring tasks, your mind does not wander - it simply disconnects - suggests a new study.
After scanning the brains of people carrying out repetitive tasks that led to lapses in concentration, the team led by Daniel Weissman of the University of Michigan, Ann Arbor, made the discovery.
To reach the conclusion, Weissman asked volunteers to spend an hour in a MRI brain scanner, identifying letters that flashed on a screen.
At times, their reactions slowed, showing that attention was wavering.
During these lapses, the scanner showed that activity between regions related to self-control, vision and language processing died down.
