Behavior Quizzes & Trivia

Our brain is something that when strained to perform when it is tried sends us signals that we need to take a break and rejuvenate. The quiz below is designed to test out what you have understood so far regarding brain and its relation to human behavior. Give it a shot and see how well you do.
