  Exploring the developing brain is a major issue in understanding what enables
children to acquire amazing abilities, and how early disruptions can lead to a
wide range of neurodevelopmental disorders. MRI plays a key role here by
providing a non-invasive way to link brain and behavioral changes. Several
modalities are used in newborns and infants to characterize the properties of
the developing brain, from growth, morphology to microstructure and functional
specialization. Recent multi-modal studies have sought to couple complementary
MRI markers to provide a more integrated view of brain development. In this
chapter, we describe successively how these approaches have made it possible to
assess the early maturation of brain tissues, to link different aspects of
structural development, and to compare structural and functional brain
development.
