Neurogenesis

Introduction

The term used to describe the process of formation of the neural system. In humans, neurogenesis continues throughout embryonic and fetal development and extends into the postnatal period.

Early neurogenesis begins with segregation of the neural plate from the ectoderm of the trilaminar embryo by folding to form initially the neural groove, which then fuses to form the neural tube (the central nervous system progenitor, brain and spinal cord) and associated neural crest. Later neurogenesis in the central nervous system is the proliferation of ventricular neural stem cells, differentiation, migration and lamination of the developing neural system.

Early developmental sequence: neural plate -> (day 18-19) neural groove -> neural tube -> Central Nervous System (brain and spinal cord).
