Night Owls vs. Early Birds
I haven’t figured out how this picture relates to the study, but it’s on National Geographic, so it must be important. I just wanted to save this link somewhere… as I post this at 4 am.
“But ten hours after waking, early birds showed reduced activity in brain areas linked to attention compared with the night owls. The “morning people” also felt sleepier and performed more slowly on tests.
Furthermore, as the day wore on, early birds showed less activity in a region deep in the brain involved in the so-called circadian master clock, which regulates our daily cycles of alertness.”
