兴奋性(Excitability)是指可兴奋组织或细胞受到刺激时发生兴奋反应(动作电位)的能力或特性。生物体与环境的关系不仅表现在物质和能量代谢方面,还表现在当环境条件发生变化时能引起机体活动的改变,由此生物体不断主动地适应环境得以生存。 生理学中常将神经细胞、肌细胞和部分腺细胞这些能够产生电位的细胞称为可兴奋细胞(excitable cell)

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
