Neuronal migration

Implies the displacement (movement or migration) of newly generated neurons from their birthplaces around the ventricular cavity in the central nervous system where most neurons are generated from the primitive neuroepithelial germinal layer to their definitive destinations (eg, the cerebral cortex layers). This phenomenon of neuronal migration in the developing telencephalon is assisted by a system of primitive and immature glial cells known as radial glial fibers whose surfaces provide a guiding role to migrating neurons.
