在胚胎发育阶段，兴奋和抑制性神经元的适当比例确立以优化大脑功能。

During embryonic development, the proper ratio of excitatory and inhibitory neurons is established for optimal brain function.

首先，科学家发现唐氏综合症小鼠的胚胎中异常兴奋和抑制性神经元的比例异常，其中抑制性细胞的数量要高得多。

First, the scientists found abnormal proportions of excitatory and inhibitory neurons in the brains of the embryonic DS mice, with a much higher quantity of the inhibitory cells.

我们总结神经祖细胞和胶质祖细胞移植能够产生兴奋性和抑制性神经元，神经营养因子能够诱导移植物来源神经元轴突向指定方向生长。

We concluded that NRP/GRP grafts can be used to produce excitatory and inhibitory neurons, and neurotrophin gradients can guide axonal growth from graft-derived neurons toward putative targets.

Now, these signals can be either excitatory, which is that they raise the likelihood the neuron will fire, or inhibitory in that they lower the likelihood that the neuron will fire.

这些刺激信号可能是兴奋性的,会增加神经元产生神经冲动可能性,也可能是抑制性的,会降低神经元产生神经冲动的可能性
