Somal translocation

Precursor cells proliferate in the ventricular zone, and the early postmitotic cells migrate from the preplate. This migration is done by somal translocation. The neurons are bipolar and attach the leading edge to the pia. The soma (or body) is then transported to the pial surface by nucleokinesis, a process by which a microtubule body wraps itself around the nucleus, elongating and contracting in succession, in association with the centromere to guide the nucleus to its final destination.
