What happens in our heads when we wake up, open our eyes and become aware of ourselves here and now? What about when we have breakfast, walk the dog and then go to work? What processes are activated in our brain when we, tired, return home, where an unresolved problem awaits us? Of course, in each of these situations, our consciousness does not follow the same algorithms. The book by Susan Greenfield, a renowned British scientist, writer and passionate popularizer of science, is based on many years of experience and recent discoveries in the field of neurobiology, the pace of development of which is amazing. Greenfield builds such a consistent, detailed and imaginative story about the most mysterious organ of the human body that it becomes practically tangible, and therefore understandable and memorable. Even if this is the first book about the brain that you have ever opened, feel free to plunge into a new paradoxical world. We assure you that the excursion will be pleasant and informative. Baroness Susan Greenfield is an MBE, a senior fellow at Lincoln College, Oxford University, a member of the House of Lords, a recipient of 32 honorary degrees from British and foreign universities, as well as many awards, including the French Legion of Honor and the title of Honorary Fellow of the Royal College of Physicians.
