这一发现表明，神经元兴奋是fMRI成像的原理。

This shows that neural excitation is what produces the fMRI images of active brain areas.

它用来获得神经元兴奋和抑制过程及神经脉冲产生机制的信息。

It is used to obtain information about the processes of excitation and inhibition in a neuron and the mechanisms that initiate nerve impulses.

目的：研究N甲基D天冬氨酸（NMDA）诱导大鼠小脑颗粒神经元兴奋毒性保护作用的机制。

Objective:To study the mechanisms underlying N methyl D aspartate (NMDA) induced excitoprotection in cultured rat cerebellar granule neurons.

These--Again, the chemicals could excite the other neuron bring up the chances it will fire, or inhibit the other neuron .

再强调一遍,这些化学物质可使另一个神经元变得兴奋,提高该神经元产生神经冲动的可能性,也可抑制另一个神经的兴奋性

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
