What takes place in our brains during motivation, jealousy, psychosis, phobias, pain, and poverty? How do our brains deal with forgetfulness, depression, moral action, creativity, and ADHD? These are just a few of the 100 questions that are addressed in this book. The answers to these questions provide insight into the workings and changeability of our brains and contain examples like Einstein, Mata Hari, Ulrike Meinhof, Messi, Sven Kramer, Amy Winehouse and many others who passed away. Each theme is introduced by an overview of images. This is an understandable book for anyone interested in the mechanisms of the brain and behavior.
