Can you distinguish between people who are visual or auditory learners? What happens when you have a blackout during an exam? Why do people still receive electroshock therapy? Why do some people remember things better than other people? Can you feel pain in your brain? Are there people or animals with more or fewer than two brain hemispheres? Do colours appear the same to everyone? Why are you grumpy after a bad night of sleep? Can I train plasticity? Is the brain more or less active during sleep?
