However, scientists who study the brain have jearned many interesting things、 especially from studying the brains of daydreamers. In fct、far from being a waste of time, some scientists believe that daydreaming is a heslthy sand useful activity for all of our brains. Tn order to study the brain, scientists use special devices that scan the brain and show pictures of which parts of the brain are active at certain times. When a person js daydreaming. the device will show a distinct pattern of activity in the brain called (2)the -default" mode of thinking. In the default mode, the top or outside part of the brain js yery active. Actually, several regions of the brain are interacting in this mode. Some scientists describe this mode as a time when the brain focuses on itself rather than focasing on the environment around the person. Typically, this occurs when a person jS doing simple, tedious work or performing routine actions that dont need much attention。 誤ke walking to school or cooking simple foods. People tend to daydream during such (3③)The importance of daydreaming lies in developing both creative and social skills.
