Countless legends surround the "last great mystery" of science, our brain. Sometimes it is portrayed as the perfect calculating machine, other times it supposedly uses only ten percent of its capacity, can be trained like a muscle, or is empathetic or selfish depending on the situation. At the same time, brain researchers today have something to say about everything—from education and psychology to nutrition—often spouting nonsense. In an entertaining and understandable way, Henning Beck, a neurobiologist and German champion in Science Slam, explains why the myths about brain training and brain food are unfounded and reveals the fascinating puzzles that brain research is truly investigating. A provocative and eye-opening book.
