Experimental design. Figure 1A indicates the block design paradigm, each functional run incorporated an ON/OFF block design with 30s of baseline scanning at the beginning and end of each scan. Four 30s blocks of stimulation (ON) by electroacupuncture or finger-tapping were separated by delays (OFF) of 30s, 60s then 30s. Figure 1B indicates point locations and conditions. Conditions 1–3 were electroacupuncture stimulation at UB 60 GB 37, and NP. Condition 4 was a finger-tapping task in which subjects were cued by a verbal prompt to tap their right thumb to their first two fingers at a rate of about 2Hz during the “ON” periods.
