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

由于抑制中间神经元的活动被阻断，它不能阻断与大脑相连的投射神经元的输出。

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.

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