In recent years, the brain has become the new playground for top-level athletes and their trainers. At a time of standardized physical training, the brain has become the new frontier of effort and performance. Taming and taming it is a priority today for anyone who wants to become and remain the number 1 athlete. The documentary film "Open Brain - In the Brains of Athletes" takes us to the very limits of the human brain, as seen through the eyes of some of the world's finest athletes. These include basketball player Rudy Gobert, Formula 1 driver Charles Leclerc, surfer Justine Dupont and footballer Pierre Emerick Aubameyang.
