And basically, the interneurons do the thinking.

基本上，中元负责思考。

And there are interneurons which connect the two.

并且有连接两者的中元。

Interneurons connect neurons within specific regions of the CNS.

而中元连接CNS中特定区域的元。

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元释放的递，致无法控制的肌肉收缩和痉挛。

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

末梢吸收这种毒素，将其吸入大脑和脊髓，在那里对中元造成严重破坏。

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

由于抑制中元的活动被阻断，它不能阻断与大脑相连的投射元的输出。

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.

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