Can I learn from a text by listening to it while I sleep?  How can I find out which stage of cognitive decline I am in, and how can I prevent Alzheimer’s disease or dementia? Is dopamine good for you and serotonin bad? Can you distinguish between people who are visual or auditory learners? How do brain cells communicate with each other? How is it possible that we can hear either ‘green needle’ or ‘brainstorm’ whilst the audio fragment remains the same? What is the purpose of brain research? Why do people still receive electroshock therapy? Can brain implants read and control our minds? Is there a link between rheumatoid arthritis and anxiety?
