Why are you grumpy after a bad night of sleep? What is fainting? Why don’t we use stem cell therapy for MS? What causes Alzheimer’s disease? Why do brain tissues have different colours? How is it possible that we can hear either ‘green needle’ or ‘brainstorm’ whilst the audio fragment remains the same? Does neuroscience provide better explanations for behaviour than psychology? Did the gigantic dinosaurs also have gigantic brains and a gigantic number of neurons? How is it that some people see an object as blue, while others say that same object is green? Are computers smarter than humans?
