title: Molecular layers underlying cytoskeletal remodelling during cortical development.
abstract: During neural development, the cytoskeleton of newborn neurons undergoes extensive and dynamic remodelling to facilitate the sequential steps of neurogenesis, cell migration and terminal differentiation. It is clear from studying the mechanisms that precipitate these functions that different configurations of the cytoskeleton prefigure the correct execution of each step and define cohorts of proteins the functions of which are indispensable for the control of neuronal migration but not terminal differentiation. These combinatorial protein functions are also predetermined by regulated gene expression and the precise subcellular localisation of their protein products. Here, we expand on this view in the context of recent data on how the cytoskeleton is regulated during the maturation of cortical neurons within the developing brain.
