EMBRYOLOGICAL DEVELOPMENT OF
THE NERVOUS SYSTEM
The cellular development of the nervous system can be
divided into sevenstages: proliferation,migration, aggre
gation, differentiation, synaptogenesis, remodelling, and
myelination (Moore & Persaud 1993,Kandel et al 2000).
The first three, proliferation, migration and aggregation,
happen early in embryological development. They are
completedby birth. The latter four are not finished at the
time of birth; in fact, some of them are just starting and
will continuethroughoutlife.Early ingestation,neuronal

The embryological processes of proliferation, migration
and aggregation can be thought of as laying down the

myelinated in order to function. In a fully functioning
nervous system, the pain system is unmyelinated, yet it
functions appropriately. But, as would be expected, the
