What Your Brain Looks Like When You Solve a Problem (gizmodo.com)
Researchers have revealed that epiphanies physically reshape brain activity. What’s more, they discovered that people remember epiphanies better than solutions reached through a more methodical approach. These results could have important implications for how instructors approach teaching in classrooms.

The mysterious flow of fluid in the brain (quantamagazine.org)
Encased in the skull, perched atop the spine, the brain has a carefully managed existence. It receives only certain nutrients, filtered through the blood-brain barrier; an elaborate system of protective membranes surrounds it. That privileged space contains a mystery. For more than a century, scientists have wondered: If it’s so hard for anything to get into the brain, how does waste get out?
