How do brain cells communicate with each other? Can a brain scan show whether people are already producing their language response while their conversation partner is still speaking? Which brain region is the most important? Why are you grumpy after a bad night of sleep? Do you learn faster when you’re younger? Why (not)? How does music affect mental health? Can I learn from a text by listening to it while I sleep?  Can you distinguish between people who are visual or auditory learners? What is the purpose of brain research? Why do some people remember their dreams and others do not?
