Why are you grumpy after a bad night of sleep? How does your brain know that you want to move? How heavy was Einstein’s brain? Does the size of your brain say anything about intelligence? How do brain cells communicate with each other? Can I learn from a text by listening to it while I sleep?  How does music affect mental health? Why do some people remember their dreams and others do not? Why is some information stored so quickly in the brain, while other information takes much longer? How is a neuron made?  Did the gigantic dinosaurs also have gigantic brains and a gigantic number of neurons?
