How do individual neurons develop and how are they integrated into neuronal circuitry?To answer this question is essential to understand how the nervous system develops and how it is maintained during the adult life.A neural stem cell must go through several stages of maturation,including proliferation,migration,differentiation,and integration,to become fully embedded to an existing neuronal circuit.The knowledge on this topic so far has come mainly from cell culture studies.Studying the development of individual How do individual neurons develop and how are they integrated into neuronal circuitry?
