excitatory

基本解释

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

If you take enough alcohol, it then goes down to inhibit the excitatory parts of your brain and then you fall on the floor and pass out.
如果你摄入足够的酒精,就会抑制在你大脑中起兴奋作用的脑组织,之后你便醉倒了

The excitatory signals are pluses, the inhibitory ones are minuses.
兴奋性信号是加,抑制性信号则是减

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

An example of an excitatory neurotransmitter is glutamate, which would normally increase brain activity and energy levels.
FORBES: What Alcohol Really Does to Your Brain
In the brain it acts as an excitatory neuromodulator, which essentially means that it facilitates greater availability of dopamine.
