Why are you grumpy after a bad night of sleep? When are we able to solve MS? Can I learn from a text by listening to it while I sleep?  Did the gigantic dinosaurs also have gigantic brains and a gigantic number of neurons? Why do some people remember their dreams and others do not? Why do some people remember things better than other people? How can I find out which stage of cognitive decline I am in, and how can I prevent Alzheimer’s disease or dementia? Why do children outperform adults in the game of ‘concentration’? Why do brain tissues have different colours? Can you unlearn sleeping in the dark?
