Title: Individualized High-Resolution Functional Mapping of the Human Brain Demonstrates the Power of Data Science
Abstract: Modern neuroimaging methods such as magnetic resonance imaging (fMRI) provide powerful tools for functional mapping of the human brain. However, the classical approach to neuroimaging is optimized for point-null hypothesis testing at the group level. This approach does not produce clear and verifiable measures of model prediction accuracy or generalization, and it does not provide much detailed information about functional maps in individuals. We have pioneered a new approach to neuroimaging that provides detailed high-dimensional functional maps of each individual's brain, and under complex, naturalistic conditions. Our methods also provide simple metrics of model prediction accuracy and generalization, and a generative link between individuals and the group. In this talk I will review our approach and its relationship to standard methods used in data science and machine learning, and provide several specific examples that illustrate the power of the approach.
