Which brain region is the most important? What is the purpose of brain research? Do colours appear the same to everyone? How is it possible that we can hear either ‘green needle’ or ‘brainstorm’ whilst the audio fragment remains the same? Can I learn from a text by listening to it while I sleep?  Are there people or animals with more or fewer than two brain hemispheres? How does personality arise? And does it change over the course of your life? Why don’t we use stem cell therapy for MS? Why do children outperform adults in the game of ‘concentration’? Do some people have stronger mental imagery than others? And does this affect how they learn?
