The Many Brains Project

Elderly people enjoying a jigsaw puzzle together.

The Many Brains Project partnered with the National Institutes of Health (NIH) All of Us Research Program to adapt a series of new game-like tasks that are now part of the All of Us Research Program’s participant experience.


The quizzes, puzzles, and other engaging exercises measure aspects of behavior that can vary from person to person, like attention span, decision-making, and emotion recognition.


Understanding how these behaviors change with mental health offers insights into how mental disorders affect the brain. It could also inform interventions or treatments so that they have the most benefit for patients.


Participation in All of Us is free and open to anyone 18 or older. People can learn more about the engaging exercises here > and learn more about joining the All of Us Research Program at
