A Spinal Functional Magnetic Resonance Imagine (fMRI) Study of Resting-State, Motor Task and Acupoint Stimulation

The spinal cord is a very important part of the central nervous system. fMRI can be applied to observe functional status of the human spinal cord. Under different conditions, the investigators will see different types of fMRI signals within the spinal cord. In resting state, the investigators might see active/inactive signals, too.
