ABSTRACT
We generally tend to think that our brain has ‘time off’, is in a passive state, when we have no tasks to perform. This is indeed the case for specialized areas in the cerebral cortex, such as the speech center, the visual center, or the motor center. Around the last turn of the century, scientists in the United States discovered that there are nervous networks that become precisely more active when people are resting. This was a major discovery in the field of our brains and the way we think, especially about ourself.
