The Default Mode Network and Mind Wandering
when a person is working on a problem but can’t solve it, the solution sometimes “appears” after the person has put the problem aside.
(p.169)
⇒ this is called ‘incubation’
Mind wandering facilitates creative incubation. Mind wandering often leads to positive feelings and increased happiness.
Mind wandering can help us plan the future, a process called ‘autobiographical planning’

Energy Consumption
Neuroscientists have long thought that the brain’s circuits are turned off when a person is at rest. However, there is a persistent level of background activity. At 2% of body weight the brain uses 10% of blood circulation and 20% of all energy consumed in the body. In contrast, functionally induced changes in blood flow are minor, most often less than 0.05 of the regional blood flow. Changes from morning to evening might be larger.
Energy consumption is huge, the evolutionary pressure limiting its size must be large.Yet, activity is only weakly correlated to external stimuli.
