Every brain has depressive tendencies and the potential to become depressed. But, the good news is every brain has wellness tendencies too. Just as a small change can start a brain spiraling down into depression, even a small shift can alter the balance, have a major impact, and begin an upward spiral too.

Changing the timing of a single stoplight may cause or prevent a traffic jam. A YouTube video may go viral from a single tweet. And sometimes tweaking the tuning of one brain circuit can start to reverse the course of depression.
