Brain-tech company Elemind gets $12 million to make a headband that helps sleep, memory, and pain without drugs.
The headband uses electric signals to change brainwaves, like turning up or down the volume on your brain.
The headband uses special software to adjust to each person's brain, so it works better and has no side effects.
In early tests, the headband helped people sleep faster, reduced shaking, improved memory, and lessened pain.
The first headband will help people feel better overall and won't need government approval.
The team making the headband includes experts from top universities like MIT and Harvard.
