excitatory

基本解釋

During embryonic development, the proper ratio of excitatory and inhibitory neurons is established for optimal brain function.
在胚胎發(fā)育階段，興奮和抑制性神經元的適當比例確立以優(yōu)化大腦功能。
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，科學家發(fā)現(xiàn)唐氏綜合癥小鼠的胚胎中異常興奮和抑制性神經元的比例異常，其中抑制性細胞的數(shù)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.
如果你攝入足夠的酒精,就會抑制在你大腦中起興奮作用的腦組織,之后你便醉倒了

The excitatory signals are pluses, the inhibitory ones are minuses.
興奮性信號是加,抑制性信號則是減

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.
這些刺激信號可能是興奮性的,會增加神經元產生神經沖動可能性,也可能是抑制性的,會降低神經元產生神經沖動的可能性

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.
