This digital Spring School focuses on three lifestyle factors in relation to brain, learning, and cognition. The lifestyle factors physical activity, nutrition and sleep are covered. On each topic a senior expert gives a digital master class in a live internet broadcast explaining and discussing the life style factor in light of its effects on brain development and functioning (latest insights regarding (f)MRI research), its relationship to the other lifestyle factors, cognitive functioning, and learning in lifelong perspective. These expert master classes go along with junior master classes in which scientists present the latest findings in the field in an interactive fashion. In a wrap-up session all the findings are integrated and summarized.
