What is the purpose of brain research? Do the male and female brain differ? Can I learn from a text by listening to it while I sleep?  How does music affect mental health? How can I find out which stage of cognitive decline I am in, and how can I prevent Alzheimer’s disease or dementia? Are computers smarter than humans? Why is sleep so essential? How does speaking multiple languages impact the brain? How heavy was Einstein’s brain? Does the size of your brain say anything about intelligence? Do colours appear the same to everyone?
