"I heard a pop in my head, like a big bubble," she said. "I tried to scream, but it wasn't a normal scream. I knew something wasn't right."

The brain generates rhythms naturally. One way to confirm this is to record the brain's electrical activity. This electrical activity results from the passage of ions (particles with positive or negative charge, such as sodium and chloride, the components of salt) across brain cell membranes. EEG (electroencephalography), a painless and harmless technique using wires (electrodes) placed on the scalp to record this activity, has been around for nearly a century. EEG reveals that much of a healthy brain's electrical activity is rhythmic, not random.

Non-invasive neurotechnology, particularly transcranial random noise stimulation (tRNS), leverages brain activity changes to significantly improve learning outcomes, particularly in challenging subjects like maths.

Welcome to Day 2 of the Creativity Challenge. Yesterday, we talked about how you can practice being creative, and noted that small, creative tasks are like stretches for your brain.
