O que acontece dentro do cérebro enquanto sua mente vagueia

What’s going on inside your head when your mind wanders? While it may feel like flipping on a screensaver, our brain is still very much at work. In fact, a particular group of our brain regions actually increase in activity whenever we aren’t focused on a task. This is known as the default mode network. And the functional connections typically include the medial prefrontal cortex, medial parietal cortex, and medial temporal lobes. There is still much debate as to what these cortical associations mean—if anything at all.
