Development
See CNS for general development of the CNS.
 * At the start of brain development, neurons are produced rapidly during neurogenesis. This is finished after ~5 months after gestation.
 * Cell migration begins shortly after the start of neurogenesis. The neurons are brought to a proper layer in the cortex by radial glial cells, which extend to the surface of the cortex.
 * After they've arrived at their proper place, neurons mature; they grow dendrites and extend their axons to appropriate targets. Maturation continues long after birth.
