What is the purpose of brain research? Can you distinguish between people who are visual or auditory learners? How do brain cells communicate with each other? Is dopamine good for you and serotonin bad? Do colours appear the same to everyone? Are computers smarter than humans? Is the brain more or less active during sleep? Why do people still receive electroshock therapy? What happens in the brain when you feel ‘confused’? What happens when you have a blackout during an exam?
