POPSTough Choices: How Making Decisions Tires Your Brain The brain works like a muscle: when depleted, it becomes less effective. Furthermore, we should take this knowledge into account when making decisions. If we've just spent lots of time focusing on a particular task, exercising self-control or even if we've just made lots of seemingly minor choices, then we probably shouldn't try to make a major decision. These deleterious carryover effects from a tired brain may have a strong shaping effect on our lives.

POPSBrain More Active While Daydreaming Than Thought Scientists have to date thought that the brain's "default network" - which is linked to easy, routine mental activity and includes the medial prefrontal cortex (PFC), the posterior cingulate cortex and the temporoparietal junction - is the only part of the brain that is active while a person's mind wanders. However, the latest study has shown that the brain's "executive network" - associated with high-level, complex problem-solving and including the lateral PFC and the dorsal anterior cingulate cortex - also gets activated while people daydream. "This is a surprising finding, that these two brain networks are activated in parallel. Until now, scientists have thought they operated on an either-or basis - when one was activated, the other was thought to be dormant," says Christoff.
