Why is sleep so essential? How do brain cells communicate with each other? How are memories made in the brain? Is there a link between rheumatoid arthritis and anxiety? Are computers smarter than humans? Can I learn from a text by listening to it while I sleep?  What happens when you have a blackout during an exam? What goes wrong in the brain when I lose focus? Did the gigantic dinosaurs also have gigantic brains and a gigantic number of neurons? How is it possible that we can hear either ‘green needle’ or ‘brainstorm’ whilst the audio fragment remains the same?
