What is the purpose of brain research? How does speaking multiple languages impact the brain? How is it possible that we can hear either ‘green needle’ or ‘brainstorm’ whilst the audio fragment remains the same? Why do some people remember their dreams and others do not? Do some people have stronger mental imagery than others? And does this affect how they learn? Can I train plasticity? What is fainting? Why is sleep so essential? How is it that some people see an object as blue, while others say that same object is green? Can a brain scan show whether people are already producing their language response while their conversation partner is still speaking?
