Summary

Parkinson's disease (PD) patients have some problem with self-initiated movement task. Compared with health controls, task meta-analysis found that PD patients showed abnormal activation in pre-supplementary motor area (pre-SMA) and putamen. And the functional connectivity has already been reported between pre-SMA and putamen in 2013. Repetitive Transcranial Magnetic Stimulation (rTMS) is a sage and painless technique to activate cortical areas. The deep brain structure can be activated via stimulating superficial cortex by rTMS. For investigating the mechanism of self-initiated movement, this project is using functional magnetic resonance imaging (fMRI) to individualize the precise localization in motor area and combining rTMS to activate putamen.

Detailed description

Healthy subject is recruiting in this project. High and low frequency rTMS will be performed, respectively. For the l-Hz sessions (low frequency), stimulation is delivered at 100% of the subject's resting motor threshold at 1 Hz continuously over 30 min for a total of 1,800 pluses. The 10-Hz stimulation is delivered at 100% of the subject's resting motor threshold via 60 trains of 3-s 10-Hz rTMS (30 pulses per train).
