The default network is a network of brain regions that become active when the individual is not focused on the external environment. The default network includes the medial prefrontal cortex, posterior cingulate cortex, and inferior parietal lobule. When a person is not engaged in a task, this network is thought to be involved in self-reflection, mental simulation, and evaluating past experiences. An fMRI scan can detect activity in this network when a person is not actively doing a task.
