At the beginning of the 21st century there was a revolution. It took place away from the city squares. And although it was not accompanied by mass demonstrations and huge headlines in the newspapers, it was astonishingly important. It is known as the flexible brain revolution, and it was based on a series of studies that found that the human brain has a constant natural ability to change, improve and even repair itself. Despite its enormous importance, the theory about the flexible brain has not yet met medical practice. Even today, more than twenty years after the outbreak of the revolution, many neuroscientists are still grappling with the question of how to harness the understanding of the flexible brain to improve a person's physical and mental health. Journey to the Brain, the new book by the doctor and neuroscientist Dr. Yossi Halamish, fills this gap, and with a combination of scientific and clinical knowledge, it promotes the new and fascinating scientific field of flexible neuromedicine. The 14 chapters of the book bring updated information about the brain and its important functions, And in the process offer practical tools to improve various functions, from improving memory and strengthening immunity to diseases to dealing with fears and anxieties. Dr. Yossi Halamish is a doctor and neuroscientist, who teaches and treats the "flexible neuromedicine" approach (psycho-neurotherapy). Dr. Chalamish developed the Do4Brain app and the Brainways training club program to improve memory and brain function. dryossichalamish@gmail.com
