Finally, intention tremors can be caused by plaques along the motor pathways in the spinal cord which can affect outbound signals like skeletal muscle control.

意向性震颤是由于脊髓内运动通路有斑块，干扰了控制骨骼肌的传出信号。

But for some people, the mapping might be off — like, every time they hear a B-flat, their brains might map it to the motor pathways that make, say, a C.

但对一些人来说，这种映射可能不稳定。比如说，每当听到一个降 B 调，他们的大脑可能会把它映射到运动神经通路上，比如说 C 调。
