Over the past two decades, substantial progress has been made in visualizing and understanding neuronal cell migration and morphogenesis during brain development. Distinct mechanisms have evolved to support migration of the various cell types that compose the developing neocortex. A specific subset of molecular motors, so far consisting of cytoplasmic dynein 1, Kif1a and myosin II, are responsible for cytoskeletal and nuclear transport in these cells. This review focuses on the emerging roles for each of these motor proteins in the migratory mechanisms of neocortical cell types. We discuss how migration can be cell cycle regulated and how coordination of motor activity is required to ensure migratory direction. © 2016 Wiley Periodicals, Inc.
