Objective   					To study the effect of different concentration of taurine on cultured cortex neuron growth and exist.
					   Methods   					The technique was builded by new-born rats cortex neuron culture.Different concentration of taurine was added to intervene and to study the culture.
					   Results   					Proper concentration taurine promoted cultured cortex neuron to exist, and to format networks among neurons.
					   Conclusion   					Taurine could promote cultured cortex neuron grow.
