Experimental paradigm (block design): each acupuncture procedure lasted for five minutes, while MR images were acquired. Needle was inserted in the acupoint before the fMRI scan started. R1, 2, 3, and 4 indicate the blocks in which no electric current was delivered; S1, 2, and 3 indicate the electric stimulating blocks.
