it covers the middle part of the prefrontal cortex and towards the back the pos derrius signal it cortex. so we're talking about the areas over the forehead. and the areas at the back in the folds of the cerebral hemispheres. this network becomes active for example when we're driving on a familiar road in good weather with little traffic. but. it was still paying attention just less than usual and a case of danger we can react right away. asked cerebral machinery allows us to stay alert and do other things it might seem simple but it's an elaborate mechanism and it's very important for our mental aqua librium. to start his research shows that the default mode network plays a fundamental role in our memory. to maintain memory it seems essential to take proper care of the brain's deformed network. that means taking mental breaks far from digital stimuli. false. i believe that the work of the brain the work of synthesizing memory can function properly only when we give the brain time to process and reflect. during this time it should not be at the mercy of external stimulation. the stimulus
