And basically, the interneurons do the thinking.

基本上，中间经元负责思考。

And there are interneurons which connect the two.

并且有连接两者的中间经元。

Interneurons connect neurons within specific regions of the CNS.

而中间经元连接CNS中特定区域的经元。

But by blocking neurotransmitters released by interneurons, tetanus toxin causes uncontrollable muscle contractions and spasms.

但是破伤风毒素通过阻断中间经元释放的经递质，会导致无法控制的肌肉痉挛。

Nerve endings soak up this toxin, drawing it into the brain and spinal cord where it wreaks havoc on interneurons.

经末梢吸这种毒素，将其吸入大脑脊髓，在那里对中间经元造成严重破坏。

Because activity of the inhibitory interneuron is blocked, it CANNOT block the output of the projection neuron that connects with the brain.

由于抑制中间经元的活动被阻断，它不能阻断与大脑相连的投射经元的输出。

This activates the projection neuron (P), But it also activates the inhibitory interneuron (I) which then BLOCKS the signal in the projection neuron (P) that connects to the brain.

这激活了投射经元(P)，但它也激活了抑制中间经元(I)，抑制中间经元阻断了与大脑相连的投射经元(P)中的信号。
