Can I learn from a text by listening to it while I sleep?  Do you learn faster when you’re younger? Why (not)? How is a neuron made?  What goes wrong in the brain when I lose focus? Are there people or animals with more or fewer than two brain hemispheres? Why are you grumpy after a bad night of sleep? Can I train plasticity?
